    Q152 activity-decile stratification of the AFF1-only and recurrent-core promoter sets
    Iqbal Lab oncofusion knowledge graph, beat Q152 · this project 2026
    used by 'AFF1-only' is a property of mid-activity promoters: zero in the bottom three deciles, zero in the top decile, and 81% of the 332 in deciles 6-8, A partner-exclusive promoter set needs a label-permutation null, not an independence one, An independence null OVERSTATES partner-exclusive recurrence 16-fold here - it is not a lower bound, and the brief that dispatched this beat said it was, At gene-body scale the AFF1-exclusive recurrent class is 6 against an exact institution-stratified null of 0.86 - but the singleton class is 63 against 74, so recurrence carries the signal and exclusivity alone does not, BLNK (SLP-65) - the B-cell receptor adapter, in the Q152 AFF1-only core and a known lineage-infidelity marker in myeloid leukaemia, EPHA7 - ephrin type-A receptor 7, a published direct promoter target of the ALL1/AF4 (KMT2A::AFF1) fusion protein, EPHA7 is the one core member with a published KMT2A::AFF1 promoter ChIP - and this beat's own data put it second on separation while denying it to the AF9 samples, In the deposit paper's own target-gene table, the AFF1-exclusive class is 64 genes against a permutation null of 2.3, and it survives call-rate matching, institution stratification, B-lineage restriction and patient collapse, IRX1 sits in the 2-of-8 tier - two different patients, not the same one twice - and is not in the recurrent core, Nine of the seventeen core promoters have a non-AFF1 sample within 10% of the threshold, and one has a non-AFF1 sample STRONGER than its own weakest AFF1 call, p279 and p318 are one patient in two lineage states, and collapsing them removes exactly one gene - NOP58 - from the recurrent core, PLANNED: margin-ranked partner-specificity scan over all 6,049 occupied-anywhere promoters, with a depth control, POU2AF1 (OCA-B / OBF-1 / BOB-1) - the B-cell-restricted OCT coactivator, in the Q152 AFF1-only core, SPRED1 - the RAS/MAPK brake whose deletion marks relapse in paediatric B-ALL, third-widest margin in the Q152 AFF1-only core, TBX21 (T-bet) - the Th1/NK master regulator, the third lymphoid gene in the Q152 AFF1-only core and the one that makes the B-lineage reading fail, The 17-promoter AFF1-only recurrent core is not more recurrence than a label permutation of the same matrix gives, The 332-promoter AFF1-only set is BELOW the count a random eight-sample arm produces (null 425), The cannot-be-occupied floor never binds at gene-body scale in any of the 27 samples, so q147's gene-scale rule is a bare 2.0x gate - and the max-versus-95th-percentile difference between q147 and q152 is immaterial there, The lymphoid look of the core does not survive an activity-matched null inside the same 332, and the pre-registered power check says 17 genes cannot carry the statistic anyway, The per-library 'cannot be occupied' floor spans 0.00x to 4.01x an average promoter, and one core gene's AFF1-exclusivity rests entirely on it, The same occupancy rule passes 0.61% of gene bodies and 10.75% of promoters, so IRX1 at 3 of 27 is 18x its gene-scale expectation where at promoter scale it was below it, The separation MARGIN, not the recurrence count, is the statistic that identifies a partner-specific promoter, Thirteen of q152's seventeen AFF1-only core promoters are absent from the deposit paper's whole target-gene table, and the four that are present are AFF1-exclusive there too, Two of the nineteen non-AFF1 samples are menin-inhibitor treated, so the specificity arm is effectively seventeen - and removing them does not rescue the core, Two of the seventeen core promoter windows are shared with a neighbouring TSS - PBLD overlaps HNRNPH3 by 38.2% and CCP110 overlaps GDE1 by 7.8%, WT1 - Wilms tumour 1, leukaemia antigen and MRD marker, and the widest-margin promoter in the Q152 AFF1-only core

    DOT1L provides transcriptional memory through PRC1.1 antagonism.
    Neville D, Ferguson DT, Heikamp EB, Lai Z, Magor GW, Lam C, et al. · Nat Cell Biol 2026
    used by 'Transcriptional memory' means two different things in this literature, and both of them are used about MLL leukaemia, A DOT1L inhibitor, which does not touch the menin-KMT2A interface, removes 70% of the fusion's enrichment from its own strongest sites - two thirds of what a menin inhibitor removes - so fusion chromatin residency is partly downstream of H3K79 methylation rather than only of menin, A menin inhibitor does not only take something away - it causes PRC1.1 to put something on, and the drug needs the cell's own silencing machinery to work, A PCGF1-null cell - a published resistance genotype - loses H3K79me2 at the most-evicted sites exactly as a control cell does (0.6123 against 0.5860), so the new stratified readout scores it as fully drug-engaged, and stratification does NOT close the resistance blind spot it was hoped to close, A second disease finds the same DOT1L-to-non-canonical-PRC1 axis in the same year - and the mark moves the opposite way, A time-resolved BRG1/RING1B/H2AK119ub CUT&RUN at BENC under menin inhibition - the inv(16) experiment, run on the right disease, Asked for the first time whether a KMT2A fusion GAINS chromatin sites under a menin inhibitor: all three pre-registered criteria fire, and the set they fire on is 52 low-amplitude bins reaching 6x the genome median, 16 of them with no gene within 20 kb and 1 of 52 on a CpG island where 66% of the fusion's real sites are, H2AK119ub - the mark every PRC1.1 claim in this graph rests on, named in fifteen entries and written in none until now, H3K79 methylation is what keeps Polycomb off - and that, not gene silencing, is what a DOT1L inhibitor actually undoes, Half the PRC1.1 intersection was free all along: Zhou's locus set is a publisher supplementary table, and 159 of this graph's gene entries are in it, Hypothesis: the menin inhibitor's effect is inactivation in place, not eviction - the fusion keeps most of its sites and loses its output, In inv(16), disrupting the fusion interface swaps BRG1 for RING1B at three MYC enhancers - the cleanest version anywhere of the experiment nobody has run on menin, In murine MLL-AF9, knocking out PCGF1 changes the menin inhibitor's effect on H3K79me2 by 0.0166 of a share ratio and the DOT1L inhibitor's by 0.0101 - both smaller than the 0.0584 two control cultures of the same line already differ by, so the mark's drug response runs outside PRC1.1, Instrument check before any conclusion: reading a browser-track .tdf with a hand-written binner and ranking the result blind returns the Hoxa cluster in five of the top twenty bins, plus Meis1, Jmjd1c, Six1, Arid2, Ncor1 and Tsc22d2 - the canonical MLL-AF9 programme, which is what the track claims to be, KDM2B, the PRC1.1 CpG-island recruiter, sits at the 99.7th percentile of its own distribution on the fusion's strongest sites in DMSO and does not gain share under either a menin inhibitor or a DOT1L inhibitor - it holds position while comparable bins drift down, Measure H3K27me3 after a menin inhibitor - the free pharmacodynamic nobody has read, and the one experiment that separates two mechanisms, Menin inhibition collapses the serine/one-carbon/ASNS programme in KMT2A::AFF1 cells - PHGDH -3.24, PSAT1 -2.40, ASNS -1.72, flat in a wild-type line - so it should re-sensitise KMT2A-rearranged ALL to asparaginase, a combination PubMed has zero records for, Menin inhibition is a reshuffle, not a subtraction: four proteins are documented to GAIN chromatin or persist under the drug, and none of them is the fusion, Menin inhibition recruits PRC1 to the BENC MYC enhancer cluster and evicts BRG1, exactly as CBFbeta-SMMHC inhibition does in inv(16), Menin inhibitors should leave half the H3K79 methylation standing - and if they do not, the menin-interface model is wrong somewhere, Nobody has convincingly found the H3K79 eraser - and that constraint sets the clock on every DOT1L inhibitor, PHGDH (O43175) - the largest menin-SELECTIVE fall in the whole serine panel, and the least essential gene in it, PRC1.1 is not both an effector and a resistance gene by coincidence: the two published readings are one activity measured from opposite ends, Prime, wash, divide, rechallenge - the one experiment that would turn 'DOT1L provides transcriptional memory' into a measurement, and it doubles as a dosing-schedule study, Re-bound at full text: still no publication puts KDM2B's rDNA repression together with a KMT2A fusion's nucleolar residence - 27 records, 10 of them congress abstract books, the rest reviews - but KDM2B ChIP-seq in MLL-AF9 cells is now deposited, so the rDNA re-map has a second and better dataset, Re-bound at full text: still nobody has asked whether a KMT2A fusion GAINS chromatin sites under a menin inhibitor - but the data to ask it are now deposited, 158 ChIP-seq samples including spike-in-normalised FLAG-MLLAF9 under VTP50469, so the class moves from never-measured to measured-not-analysed, Re-bound at full text: the H3K79me2 decay half-life is still unmeasured - one paper in 12.4 million full texts contains the phrase 'half-life of H3K79me2', it is an unnumbered assertion citing a 2010 review, and the MLL::AF9 degron time-course that could have measured it uses the word zero times, The KMT2A-fusion causal chain: six links, one measured ordering, and two arms that are parallel rather than sequential, The premise that GSE260742 'carries a ChIP-Rx spike-in' does not survive reading the deposit: zero of 158 sample records mention a spike-in, the only ChIP-Rx experiment in the paper is an H2AK119ub panel that is not identifiable among the deposited samples, and 152 of 158 samples ship only an unnormalised igvtools .tdf, The serine arm replicates in a third KMT2A::AFF1 line from an independent laboratory - PHGDH -2.77, PSAT1 -2.17, GPT2 -2.34, ASNS -1.16 - but the ISR output genes do not, and it survives PCGF1 and BCOR knockout, The washout data cannot say whether the serine/ASNS collapse is durable - the washout control never recovers, ASNS is undetectable in the line, and the housekeeping drifts in opposite directions in the two matrices, Three unnamed things at once: the DOT1L-PRC1.1 deposition names the fusion, the cell types and both inhibitors with concentrations, Titrate PRC1.1 capacity against menin-inhibitor response, and measure H2AK119ub on the same timecourse as H3K79me2, What fills the space: RING1B and BCOR arrive at the fusion's sites under BOTH drugs, but the DOT1L inhibitor puts them everywhere on the fusion's territory while the menin inhibitor puts them only in the quartile where the fusion is most completely evicted - and at Meis1 RING1B rises 16-fold

    used by "Seen in MLL-AF4 and no other bait" excludes AFF1, AFF4 and ELL — the three most AFF1-specific proteins in the experiment — and keeps ACADM and GLUD1, A dimension can be saturated in the corpus and empty in the entry named for it, and the reporter that measures coverage cannot tell the difference, A ratio-of-ratios combines four independent tracks and a pair ratio combines two, so its noise floor is wider by a factor of root two in log space - and cycles 101 and 102 scored two ratio-of-ratios against a pair floor. Applying the correction to the measured 9.4% peak floor gives 13.5%: VTP's 1.3% stays comfortably inside, and SGC0946's 22.8% stays outside but its margin falls from '2-6x outside' to 1.7x, A sharper test than complex enrichment: is the claimed partner's OBLIGATE partner also there? — and its fourth failure is the one protein the source paper named as its own non-selectivity control, Across all seven MLL-fusion baits, how deep a bait's fixed top-300 list runs into non-significance predicts how many "specific" partners it appears to have — Spearman +0.821, exact p = 0.034, and MLL-AF4 is the extreme on both axes, Against a correctly measured same-condition floor, a menin inhibitor's effect on H3K4me3, H3K79me2 and H3K27me3 is a genome-wide redistribution - up in the decile below the peaks, down monotonically to the sparsest decile - while its effect on the FUSION stays confined to the top 0.1%. The drug displaces the complex at the peaks and moves the marks everywhere, AKAP95 IDR1 co-condenses with the KMT2A N-terminal fragment - the one AKAP95 contact that lands inside the region every KMT2A fusion retains, AKAP95 reaches this disease by two separate routes - through WRAD/DPY30 and through the retained KMT2A fragment - and only the second one survives the fusion, ARID4B / SAP180 (Q4LE39) - the Sin3A-complex subunit that shares SIN3A's HDAC1-binding region, is in the MLL-fusion interactome, and is the second of only two epigenetic vulnerabilities a CRISPR screen found in KMT2A-rearranged ALL, Auditing the graph against the PI's brief, not against its own ledger (run), Cycle 102 declared before it ran that an input pair 'bounds library and coverage variation but NOT ChIP efficiency' and is therefore a LOWER BOUND - the size of that underestimate is now measured in human KMT2A::AFF1 MV4;11 and it is sixteen-fold at the peaks: 0.6% for an input pair against 9.4% for a menin ChIP pair over the same bins, in the same cells, on the same day, Cycle 104's M1 - 'no scoreable mark moves at D1, so the menin inhibitor's chromatin effect is proportionally a peak phenomenon' - DOES NOT SURVIVE. The same-condition floor at D1 is 2.4%, not the 10% borrowed from the top stratum, and all three scoreable marks exceed it (H3K4me3 9.8%, H3K79me2 7.8%, H3K27me3 4.8%). Two of the three exceed even GSE260742's OWN stratum-matched input floor, which was on disk the whole time. Cycle 104's alternative M2 fires instead, Cycle 104's open question - 'why do two marks break the floor at D10 and not at D1?' - has a false premise. Against the measured same-condition floor of 2.3% at D10, THREE marks break it there (H3K79me2 16.2%, H3K4me3 12.6%, H3K27me3 6.3%), and the same three break it at D1 too. There is no D1-versus-D10 contrast to explain; there is a continuous bulk gradient that a single borrowed 10% figure had chopped in two, Every IntAct number in this project is drawn through a query that misses half the record - and what it misses is the taspase1 fragments, GATAD2A / p66-alpha (Q86YP4) - the subunit that bridges NuRD's two modules, the best-ranked NuRD gene in this project's KMT2A-selectivity scan, and present in the pan-fusion interactome under MLL-AF9 but NOT the index fusion, GATAD2B / p66-beta (Q8WXI9) - the NuRD scaffold with the broadest presence in the pan-MLL-fusion interactome, five of seven baits and still not the index fusion, and a haploinsufficiency syndrome that caps any therapeutic idea, GLUD1 is a hexameric mitochondrial matrix dehydrogenase recovered on 11 spectra with non-zero control signal from a nuclear pulldown — and this corpus has already declined one KMT2A partner whose sole source was a cryo-EM structure of GLUD1 — declined, H3C1 stays rejected, and now with the two numbers the registry row lacked: its accession carries TEN gene names, and removing every substrate and ribosome symbol moves interactome coverage 43.8% -> 46.1%, H4K20me1 - the transcription- and replication-linked H4 state, whose gene-body level tracks Pol II; it HAS been profiled genome-wide in human haematopoietic stem cells twice, and a query scoped to 'leukemia' cannot see either dataset, HDAC1 and HDAC2 belong to at least five different corepressor complexes, so an HDAC1/2 observation names no complex - and this graph carried both enzymes without the scaffolds that would tell them apart, In all 24 read-queue rows inspected, the candidate is the BAIT and this project's protein is the prey - nobody has ever tagged KMT2A, AFF4, menin or PSIP1 and found any of them; plus seven bounded rejections, In human KMT2A::AFF1 MV4;11 (monocytic, not B-lineage), the vehicle-versus-vehicle noise floor is 9.4% at the top 0.1% of menin/MLL1 sites and 0.1-2.6% in every other stratum - so cycle 102's borrowed 4-10% band is about right AT THE PEAKS and four to five times too generous everywhere else, and it was applied everywhere, IntAct curates SEVEN MLL fusion proteins as first-class interactors - ENL, AFF4, AF9, GAS7, ELL, AF6 and CALM - and not the index one, King verification of q181: the epigenetics field is NOT hollow (1 of 218 empty), the mark regex has three further blind spots including chromatin accessibility in 25 entries, and my own attempted correction of q181 was wrong, KMT2A::AFF1 has no measured fusion-specific interactome: the one dataset that appears to supply one is a rank-selected tail in the wrong lineage, and the question is open rather than answered badly, KMT2A::AFF1–LEF1 is one AP-MS row (p 0.0261, 10|8 spectra) in a Jurkat T-ALL host, where LEF1 is a resident lineage factor; it is the only one of the six AF4-specific candidates with non-zero negative-control signal, and no Wnt co-factor was co-recovered — declined, LEF1 — the Wnt/β-catenin DNA-binding factor of the T-lineage, named as an MLL-AF4-specific interactor in a T-ALL cell line and with essentially no B-lineage or KMT2A literature, Lineage-split DepMap: neither USP2 nor MAML2 is a dependency in KMT2A-rearranged lines, and USP22 is, MBD3 (O95983) - the methyl-CpG-binding subunit that does NOT bind methylated DNA, and a validated KMT2A::AFF1-selective CRISPR vulnerability that is absent from every column of the pan-fusion interactome, MBTD1 - the H4K20me1/me2 reader inside NuA4/TIP60, the quiescence brake on adult haematopoietic stem cells, and the 3' partner of ZMYND11::MBTD1 whose methyl-lysine cage the fusion carries and does not use, Measured: the cell-type, cell-state and epigenetics literature for KMT2A and MEN1 was NOT missing from this corpus - 7 of 16 load-bearing papers were already cited, one of them 32 times, and 0 of 16 were in gene-kmt2a, MLL fusions engage NuRD's remodelling arm without its deacetylase arm - and if so, every 'NuRD is repressive' inference in this graph is pointing the wrong way, MTA2 / MTA1L1 (O94776) - the NuRD scaffold that clamps HDAC1, recruited in T lymphocytes by BCL11B, and absent together with MTA1 and MTA3 from every column of the pan-MLL-fusion interactome, No experiment has ever ASKED whether MTA2, MBD3, GATAD2A or SIN3A binds a KMT2A fusion - four of them were nonetheless in the lysate of a seven-fusion pulldown, and the class of that absence is measured-not-reported, not never-measured, No orthogonal validation exists for any of the 110 MLL-AF4-specific partners, as far as four declared bounds can see — and the one partner the paper itself followed up, SETD2, is on the opposite list, shared by all seven fusions, Only 2 of this graph's 26 bounded absences name a deposited dataset — the corpus asks whether a paper exists and almost never whether the data does, Only 69 of the 529 entries carrying absence_class are absence entries, and every conceptually novel token authors reached for - partially-measured, measured-and-contradicted, not-worth-measuring - is on an interface entry, where the thing being graded is not an absence at all, PLANNED: re-search the public PXD009338 raw files for the twelve corepressor subunits the published table truncated away - one compute job that closes twelve measured-not-reported absences and adjudicates the module-split hypothesis, Prediction 5 of hyp-q117 contains three separable claims - normal eviction, no silencing, and return on withdrawal - and the deposit it names supports one of them only through a clause it never states; the eviction and silencing clauses need tracks the NTvKO arm does not carry, and withdrawal is absent from all 158 samples, Reading the fusion interactome by COMPLEX rather than by protein — and the strongest signature in it is a known contaminant, which is what makes the rest readable, Repeat the one published RPA-at-the-KMT2A-breakpoint experiment in a haematopoietic cell, with an RPA-dose arm - the protocol is fully specified in a 2010 paper whose every arm used fibroblasts and a CML line, and whose primer sets, dose and controls are all published, RPA1 and RPA2 are curated HGNC aliases of POLR1A and POLR1B, and RPA34 - a UniProt synonym of RPA2 - is an alias of POLR1G, so three of the ssDNA clamp's names point at RNA polymerase I subunits; the hazard is in symbol-based DATABASE lookups, not in PubMed, and the measured contamination says which, RPA2 is the only compartment-compatible candidate of the six and the corpus already has a KMT2A resection thread it would fit — but it is an abundant ssDNA-binding subunit on 6 spectra in a benzonase-treated lysate with no RPA1 or RPA3 co-recovered — declined, thread flagged, scripts/is-symbol-covered.py returns 'no match' for BRAF, AKT1, EGFR, CD226 and IRF2 - all five have a declined interface entry. The `interface-` prefix in its PREFIXES list can never match anything., SIN3A (Q96ST3) - the scaffold of the OTHER HDAC1/2 corepressor complex, a 5' fusion partner in infant B-ALL and in myelodysplasia, and present in three MLL-fusion AP-MS columns but not the index fusion's, The 297 absence-bearing entries that are not named absence-* split cleanly by entry type: the 109 gene and protein entries are bounded by title/abstract search (7 of 7 hand-read), the analyses are bounded by deposited data (0 of 6), and the weighted abstract-level share is 60% - indistinguishable from the 59% measured on the 39 named ones, The corpus holds 42 of 42 pan-fusion partners and 1 of 110 MLL-AF4-specific ones — the inverse of the standing priority, and every mechanism that produced it was a reasonable local decision, The coverage checker the standing brief mandates overwrites its own HGNC index mid-loop, so every symbol after the first no-match is answered wrongly - and the wrong answer is 'treat any answer as unsafe', The interactome coverage figure is computed on 651 of the 1,015 IntAct rows available - 64% - and the gap is worst for menin and LEDGF, the two baits the menin-interface hypothesis rests on, The missing reagent is a spike-in, not a better statistic: a spike-in-normalised H3K4me3, H3K79me2 and H3K27me3 ChIP-seq at 72 h of a clinical menin inhibitor in a KMT2A-rearranged human line, which is the only design that can tell a genuine genome-wide mark redistribution from the compositional shadow of a peak-localised change, The MLL-fusion interactome recovers corepressor SCAFFOLDS and not their HDAC1/2 catalytic core: NuRD splits 5/7 remodelling arm versus 0/7 deacetylase arm (Fisher p = 0.021), and HDAC1, HDAC2, RBBP4 and RBBP7 are absent from all seven baits, The NuRD complex - two separable modules, three paralogue choices that change what it does, and a graph that carried its ATPase and its shared core but never the scaffolds that make it NuRD, The reopening watchlist read for the first time: 0 of 10 candidate papers meet their condition, 8 of 10 watched decisions returned nothing, and not one of the ten titles names the gene it was retrieved for, The rule-64 complex-form query that the RPA2 decline flagged as unrun has now been run, and it finds a published damage-state RPA occupancy measurement AT the KMT2A breakpoint cluster region - so two of this corpus's absence entries carry ids that are broader than the claims inside them, The selection control, run at last: two biologically identical vehicle-treated input libraries produce a MONOTONE decile gradient from 0.9040 to 1.2349 - wider than the real FLAG gradient cycle 103 called a finding - when the strata are cut on the pair itself, and are flat within 0.73% and non-monotone when the strata are cut externally. Monotonicity across deciles is therefore NOT evidence against a coverage artefact. Cycle 103 is safe because it cut externally, The standing duplicate-check exits 126 and returns nothing at 3,000 files; it caused no duplicate ids, but the audit it should have been doing found two superseded entries that never name their successor - one of them a live safety verdict, The third silent-failure class, audited after being named in four king logs: exactly one of seven bigWig analyses is raw-coverage, the single incommensurable pair is already labelled three times, and the cross-pipeline ratio comparison was bounded at the point of measurement, The two silent-failure classes found in cycle 59 did not propagate through the corpus - 13 candidates, all legitimate on reading, and the audit corrected itself twice before it found anything, This graph states 624 falsifiers and records the outcome of 17 - a figure this entry first published as 8, because the detector did not know the corpus's own ALL-CAPS convention for recording one, This repo's "the pan-fusion core is 7.4-fold cleaner per unit signal than the singleton tail" divides one control column by a denominator summed over seven baits — on a per-bait denominator the ratio is 1.06 and p goes from 0.074 to 0.91, Three quarters of KMT2A::AFF1's top partners are shared with other MLL fusions — and the two analyses that said otherwise were both artifacts of how the source table was built, Two measurement defects confirmed: a denominator summed over seven baits made the pan-fusion core look 7.5x cleaner than it is (corrected fold 1.06, p 0.91), and my own gap report counts as coverage in the join that measures the gap, What the Polycomb beat searched, what it counted as absent, what it read and rejected, and the two absences it got wrong before hand-back, When a family shares a complex, the result is family-selective, not member-selective - the protein version of this graph's inhibitor-class rule

    used by "SWI/SNF" is three different machines: cBAF, PBAF and ncBAF - and only one of them looks KMT2A-selective, 4,589 genes with no prior, and menin comes first (run), A gene-set permutation is anti-conservative for a protein complex, and the fix is to permute the other margin, A null that costs one command, run first rather than afterwards - and SSRP1 is genuinely LESS required in KMT2A-rearranged lines, while the rest of the chaperone layer is not much of anything, AF10/MLLT10 fusions drive aberrant self-renewal of non-stem progenitors — found only by opening the paper, AFF1 / AF4 — the 3' half of the fusion, and a target with almost no structural footing, AFF2 (FMR2) — the SEC-L2 scaffold, and the AFF-family member with no dependency anywhere, AFF3 (LAF4) — the AFF-family scaffold of SEC-L3, and a KMT2A fusion partner in its own right, AFF4 — the textbook SEC scaffold that KMT2A::AFF1 cells need LESS than other leukemias, AFF4 has never been placed in a haematopoietic cell state — every SEC cell-state result is in another tissue, AFG2A / SPATA5 (Q8NB90) - a 55LCC replisome-proteostasis ATPase that co-purifies with KMT2A and menin, and whose CURRENT symbol cannot retrieve its own source paper or any of its function literature, AFG2B / SPATA5L1 (Q9BVQ7) - the second 55LCC ATPase, the only read-queue member with an annotated nuclear pool, pan-essential in 95.5% of lines, and the one that touches PSIP1, ALDH1L2 (Q3SY69) - the second-largest fall in the serine/one-carbon panel (-3.40), named nowhere in this graph, zero of 1,258 DepMap lines require it, and a tumour SUPPRESSOR where it has been studied, ALL-PO (CVCL_1069) — an infant KMT2A::AFF1 line that is already in DepMap and has never been screened, AQR (Aquarius) - a spliceosomal RNA helicase whose loss impairs MLL-rearranged leukaemia stem cells, Are the menin partners outliers, or did we pick them? (run), ARID1A (BAF250A) - required in the MLL-AF9 screen, present at the Myc enhancers, and flat in every selectivity measure, ARID2 (BAF200) - the PBAF subunit whose loss ACCELERATES MLL-AF9 leukaemia, and which is nonetheless required to maintain it, ASH2L — the WRAD subunit that has DPY30's essentiality profile and none of its co-dependency signal, ASH2L is studied in leukaemia and has never been placed in a cell state there — and the KMT2A-rearranged arm needs it LESS than average, ASH2L: the only WRAD subunit ever perturbed in a KMT2A::AFF1 cell, once, weakly, ATF3 (P18847) - the one cascade member the DOT1L inhibitor hits HARDER than the menin inhibitor, and a transcriptional REPRESSOR being counted as a stress output, ATF4 / CREB2 (P18848) - the hub this graph inferred from its targets and never wrote, and its own transcript does not move under either menin inhibitor, ATF5 / ATFX (Q9Y2D1) - the most reproducible repression in the earlier dataset, and the three probe values the graph quotes are SEM, not RS4;11, ATXN7L3 — the shared adaptor that actually sets H2Bub levels, and a KMT2A-selectivity hit nobody in this field has looked at, BAF inhibition against the menin axis: on the evidence it is a complement, not an alternative - and the case rests on one laboratory, BARD1 (Q99728, 777 aa) - BRCA1's obligate partner, and the member of the cascade that actually touches the chromatin: its PxVxL motif at 569-573 binds HP1, and CTCF binds BARD1 rather than BRCA1 in an undamaged cell, BCL2 — the one co-dependency in this beat that already has an approved drug pointed at it, BCOR — the other side of the CBX8 conflict, and a target you would be inhibiting in the direction of disease, BCORL1 — the BCOR paralogue that is in the only crystal structure of the PRC1.1 core, and is the one PRC1.1 subunit nobody has tested in KMT2A-rearranged leukaemia, BICRA (GLTSCR1) - the ncBAF scaffold, zero PubMed records in KMT2A leukaemia, and a lineage-independent dependency in KMT2A-rearranged lines, BMI1 - the self-renewal gene that KMT2A fusions can do without, because HOXA9 covers for it at the same locus, BMI1, CDKN2A and CDK6 are one circuit, not three genes - and in KMT2A-rearranged disease it has a loop nobody has measured, BOD1L (BOD1L1) — the top SETD1A co-dependency, and the only candidate in this cycle tested by CRISPR tiling in a KMT2A::AFF1 line, Bounded absence: no published CRISPR or dependency screen in any infant-derived KMT2A::AFF1 model, BRCA1 (P38398, 1,863 aa) - named in 19 entries of this graph and never written: the HR mediator that CTCF and the H3K9 machinery are now reported to license at a break, and the only cascade member with a human therapy-related-leukaemia signal after topoisomerase II therapy, BRD4 — the best-drugged protein in this beat, and the one whose clinical result is already in and disappointing, BRD9 — dispensable in the average cell, rank 39 of 17,728 in KMT2A-rearranged lines, and with an on-target proof most epigenetic targets never get, BRD9 survives the null; CEBPA sits at the median of random genes, BRIP1 — downstream effector; rank 22 of 8,269 for KMT2A-selective dependency, and no KMT2A literature at all, CALM-AF10 was meant to separate the menin axis from the HOXA programme - and the indirect evidence has now turned against separability, because KMT2A-free HOXA lesions keep proving menin-DEPENDENT, CBS (P35520) - the largest fall in the whole panel (-4.07), a token that collides with Cajal bodies AND CTCF binding sites, and a germline phenotype whose hallmark is thrombosis, CBX3 / HP1-gamma (Q13185, 183 aa) - the EUCHROMATIC HP1 paralogue, and the one CTCF actually prefers: the reader that carries BRCA1/BARD1 onto H3K9-methylated break chromatin, flat in DepMap, and a fusion partner in one KMT2A::AFDN AML patient, CBX5 / HP1-alpha (P45973, 191 aa) - the H3K9me3 reader that recruits the writer, the writer's destroyer and the second writer; and the one member of that circuit with a published pro-leukaemic role, as part of an MLL leukaemia stem-cell programme that immortalises myeloid progenitors WITHOUT Hoxa or Meis, CBX8 — the one place in this interactome where two good papers flatly disagree, and DepMap takes a side, CCND3 (cyclin D3) — the scan's rank-4 hit, and the only one of the four with a drug class already in children, CCNT1 / cyclin T1 — the regulatory half of P-TEFb, and the one part of the elongation core with any dependency variance, CCNT2 / cyclin T2 - expressed in every KMT2A-rearranged line and needed by none of them, so the cyclin T split is real rather than an expression artefact, CDC73 / parafibromin — the PAF1C subunit that was genetically tested, and a second tumour suppressor required by the fusion, CDK12 - a different kinase with a different cyclin, and in KMT2A-rearranged lines it is an anti-dependency, CDK13 - rank 171 of 17,728, equally deep in both lineage halves, and essentially unstudied in leukaemia, CDK4 - the other half of the class name, and it is NOT the gene this disease needs, CDK4/6 inhibition in KMT2A-rearranged leukemia — the class was already tried, and the trial never reported, CDK6 - the kinase the KMT2A-r rationale actually rests on, and the pan-essentiality flag and the selectivity are both true, CDK9 - the kinase the whole SEC story runs through, which this graph held only as half of a two-protein summary entry, CDK9 inhibition in KMT2A-rearranged infant leukemia — the most direct hit on the hijacked machinery, and the narrowest window, CEBPA — ranks 25th on the KMT2A scan and sits at the median of random genes, Cell type or the fusion? MV4-11 LOOSENS the confound the graph's own lineage split was built on - but its founding paper calls it biphenotypic, CHAC1 / BOTCH (Q9BUX1) - the largest single effect in the whole menin-inhibitor response (-5.11 log2) and a glutathione-degrading pro-apoptotic enzyme, named nowhere in this graph until now, Co-dependency scan: what else does a menin-dependent cell need? (run, not planned), Compute: which backend for which piece of phase-2 work, and the one constraint that matters for each, CREBBP (CBP) — binds the KMT2A transactivation domain, which no fusion keeps, CSNK2A2 - CK2's other catalytic subunit, expressed in every KMT2A-rearranged line and, if anything, slightly favourable to lose, CTH (P32929) - gene_exact returns TWO reviewed records and the second is VSIG2, a third instance of rule 62 on the same symbol the Ensembl resolver already got wrong, CTNNB1 (beta-catenin) — the Wnt link inside DotCom, and the one piece of KMT2A biology that is not chromatin, CTR9 — a PAF1C subunit the field assumes is a fusion partner, with no paper that tested it, CXCL12 (SDF-1) - the marrow retention chemokine this graph already had a mechanism entry for and no entry for the protein, CXCR4 - named in eighteen entries of this graph with no entry of its own, and the one niche molecule with a drug, a paediatric trial and a direct KMT2A-r experiment, CXXC1 (CFP1) - a CpG-reading COMPASS subunit that binds MLL1 and recruits it to HoxA7, and whose CXXC domain cannot substitute for KMT2A's in a fusion, CXXC4 (IDAX) - TET2's CXXC domain, sitting on a separate gene after an evolutionary inversion, and annotated cytoplasmic only by similarity, CXXC5 (RINF) - the one CXXC reader measurably down-regulated in KMT2A-rearranged AML, which is the only direction-of-change any family member has in this disease, Dataset: DepMap CRISPR essentiality - the bulk download is now behind a captcha, and this changes how phase 2 must be built, DDIT3 / CHOP (P35638) - the cascade's middle node, and the symbol whose two reviewed human records and 16,893-record alias are the worst identifier trap in this beat, Decitabine - degrades DNMT1, and in ALL cells it degrades KMT2A too: the hypomethylating agent with two mechanisms and a menin-inhibitor combination already in the clinic, Decitabine's target is a pan-essential gene, and KMT2A-rearranged lines depend on it LESS than other leukaemia lines - rank 16,949 of 17,728, DEK - a chromatin architectural protein that gatekeeps H3.3 and boosts HP1alpha, is a fusion partner in its own right, and is the substrate behind this graph's third CK2 route, DepMap across the whole CTCF-BRCA1 licensing cascade in one call: CTCF is a near-total pan-essential at -1.83, BARD1 is deeper than BRCA1, the HP1 paralogue that matters is flat while the one that does not is four times deeper - and DNA2's row has 80 screens where everything else has 1,258, DepMap cannot answer whether MEN1 is selectively required in NUP98-rearranged lines, because it contains none — and it takes only ~3 to answer it, DepMap co-dependency cannot rank the 97 unwritten interactome partners either, pan-cancer OR restricted to leukaemia lines: mean r 0.008 rising to 0.023 under restriction while the leukaemia-matched null rises with it, giving 1.08x the chance-expected count. Recomputing the null on the restricted lines is the only thing that stopped this being reported as a discovery, and my first pass criterion called a below-chance result a PASS, DNA2 (P51530, 1,060 aa) - EXO1's redundant partner in long-range resection, dual mitochondrial and nuclear, and the gene whose DepMap row is measured in 80 screens where every other cascade member has 1,258, DNMT1 - the antagonist: its CXXC domain reads unmethylated CpG in order to STOP methylation, and it is the only heterologous CXXC that runs an MLL-AF9 leukaemia, Do the other WRAD subunits behave like DPY30? (run, not planned), Does a menin inhibitor create a BMI1 dependency? A two-arm knockout-under-drug experiment in KMT2A::AFF1 cells, with the CDKN2A readout that decides the mechanism, Does the menin co-dependency survive lineage adjustment? (run), DOT1L — the target where excellent chemistry met an indirect interaction, DPF2 (BAF45D) - a cBAF-specific reader required in MLL-AF9 cells, with one PubMed record in this disease and no selectivity signal, DPY30 — the smallest COMPASS subunit, and the only one that behaves like a selective dependency, DPY30 aims the H3K4 machinery while ASH2L powers it, which is why only DPY30 tracks menin, EAF1 — the interactor with an actual subnuclear phenotype: an MLL fusion evicts it from Cajal bodies, and the bodies themselves fall apart, EAF2 (U19) — the EAF paralogue whose ELL-binding domain is a mapped tumour-suppressor module, described entirely in prostate cancer, EHMT2 / G9a - the H3K9me1/2 writer that sets whether the KMT2A LOCUS ITSELF rearranges, and whose loss delays MLL-AF9 AML in a supplementary figure nobody can find, EIF2AK4 / GCN2 (Q9P2K8) - the amino-acid-sensing eIF2alpha kinase: transcript flat, and NOTHING has ever been published about it in any KMT2A-rearranged system under either name, ELL — rank 7 on selectivity and the deepest common-essential in the top ten, with one NMR fragment to its name, ELL has never been placed in a cell state — its entire leukaemia state literature is its own fusion transcript used as a residual-disease marker, ELL2 — a SEC subunit that almost no cell needs, next to a paralogue almost every cell needs, ELL3 — the third ELL paralogue, which marks enhancers and recruits SEC rather than sitting inside it, Endogenous aldehydes and silenced ALDH2 — the rival explanation for an FA dependency in acute leukaemia, and the only one with an experiment behind it, EP300 — the acetyltransferase whose paralogue split is the finding: p300 is the 108th most KMT2A-selective gene, CBP is the 16,950th, EPC1 - the NuA4/TIP60 subunit whose C-terminal fragment grips MBTD1, making it the contact a leukaemic fusion cannot do without and the mildest dependency in that whole complex, Erasing H2Bub: three deubiquitinases share two adaptors, and removing the enzyme the field names lowers the mark instead of raising it, ERG - a heptad stem-cell transcription factor whose 15 mentions in this graph are mostly about OTHER diseases, and whose best-established role in B-ALL is loss of function, not cooperation, Every age-restricted target nominated by the model is pan-essential or invisible, Every gene in the H2B ubiquitination axis, ranked against the whole genome for KMT2A selectivity — and the writers are not selective, Exactly one gene in 8,248 beats menin, and it is FLT3, EXO1 (Q9UQ84, 846 aa) - the long-range resection nuclease at the bottom of the CTCF cascade, and the point where this graph's two independent 2026 HR papers meet: CtIP starts the resection, EXO1/DNA2 finish it, Expressed, required, maintains — three different claims about where a gene matters, and the graph must label which one it has, EZHIP (CXorf67, CATACOMB) - a protein that jams PRC2 by pretending to be an H3K27M oncohistone, and the 3' payload of MBTD1's other fusion, FAAP100 — FA core complex; rank 36 of 8,269 for KMT2A-selective dependency, and no KMT2A literature at all, FACT (SPT16-SSRP1) - the chromatin arm of transcription elongation, and a clean negative result for the KMT2A::AFF1 interactome, FANCA — FA core complex; rank 20 of 8,269 for KMT2A-selective dependency, and no KMT2A literature at all, FANCD2 — the FA effector menin binds, and the weakest FA gene in this graph's own selectivity scan, FANCF — FA core complex; rank 11 of 8,269 for KMT2A-selective dependency, and no KMT2A literature at all, FANCG — FA core complex; rank 27 of 8,269 for KMT2A-selective dependency, and no KMT2A literature at all, FANCI — ID2 module; rank 15 of 8,269 for KMT2A-selective dependency, and no KMT2A literature at all, FANCL — FA core complex; rank 26 of 8,269 for KMT2A-selective dependency, and no KMT2A literature at all, FBXL19 - a CpG-island reader that delivers CDK-Mediator and RNF20 to developmental promoters, and whose experimental localisation is mostly cytoplasm, Fifth explanation for the Fanconi signal: it runs through menin binding FANCD2, not crosslink repair — tested, refuted, prior 0.07, First systematic enumeration of the KMT2A fusion interactome, and the diff against this graph, Five new arginine-axis entries in one day, and not one of their genes is a selective dependency - in an instrument that recovers MEN1 at p=5e-05 and TDRD3 is not a dependency at all, FLT3 / CD135 — the strongest non-tether co-dependency, and a target the field may have written off on a badly executed trial, FLT3 is the second largest KMT2A-selective dependency and it is HEAVIER in B-lineage than in myeloid cells, Four ways a WDR5 result can be true and have nothing to do with KMT2A, FOXC1 - a mesenchymal forkhead factor derepressed in HOXA-high AML that blocks monocytic differentiation, with a real mechanism and zero published connection to KMT2A rearrangement, GAS7 — growth-arrest-specific F-BAR protein, the second pillar of the forced-oligomerisation model, GATA2 - the least KMT2A-selective gene on this beat, ranking 17,591 of 17,728, and a factor whose leukaemia biology is about stemness and chemoresistance rather than about the fusion, GFI1 — the repressor that LSD1 inhibitors actually work through, and the scan hit whose literature points the opposite way, GPHN (gephyrin) — synaptic scaffold and molybdenum-cofactor enzyme, KMT2A fusion partner in t(11;14)(q23;q24), GPT2 (Q8TD30) - the EARLIEST-moving and third-most menin-selective gene in the serine arm, and the one REH cannot control because it is below the array floor there, H2B ubiquitination is upstream of the fusion's defining mark and is still not a target, because the fusion uses a general mechanism rather than a special one, H2BK34ub — a second ubiquitination site on H2B that also stimulates DOT1L, written by MSL1/MSL2, and important at HOXA9 and MEIS1, HB11;19 (CVCL_8227) is KMT2A::MLLT1, not KMT2A::AFF1 — and it is the most menin-dependent line in the panel, HCFC1 (HCF-1) — a founding member of the wild-type KMT2A complex that the fusion cannot bind, HEXIM1 - the brake pad, the only part of the reservoir anyone has deliberately raised in a KMT2A-rearranged cell, and the result was that the leukaemia grew less, HEXIM2 - the paralogue that holds the bound P-TEFb pool constant when HEXIM1 is removed, which is why single-gene experiments on this axis read flat, How BAF maintains KMT2A-rearranged leukaemia: it holds the blast undifferentiated, and it does so in other leukaemias too, HOXA10 - named in 27 entries as part of the HOXA output and never written; a posterior HOX paralogue that is regulated with HOXA9 and tested far less often, HOXA7 - the one HOXA paralogue besides HOXA9 with a published loss-of-function requirement for MLL-fusion transformation, and the requirement was shown in vitro only, HOXA9 — required for survival of established MLL-rearranged leukemia, and dispensable for starting it, Hypothesis (first clause REFUTED 2026-09-21): the fusion's core dependencies may be cell-type-invariant, but the cell type itself is not fixed, ICE1 — the 2,266-residue scaffold of the little elongation complex, the subunit that acts at initiation, and zero papers connecting it to leukaemia of any kind, ICE2 — the fourth LEC subunit, the one with no assigned step, no structure, and no leukaemia literature, IDH1 - the same oncometabolite, the same assay, and NO enrichment in KMT2A-rearranged AML (6.7% vs 7.6%, p = 0.53): the control that makes the IDH2 result interpretable, IDH2 - the hypermethylating co-mutation that IS enriched in KMT2A-rearranged AML (16.0% vs 10.4%), at p = 0.0004 and not the p < 0.0001 the abstract claims, If HOXA9 substitutes for BMI1 at CDKN2A, then a menin inhibitor should CREATE a BMI1 dependency that does not exist at baseline, IGF2BP3 — an RNA-binding protein required for MLL-Af4 leukaemogenesis in mice that CRISPR barely touches in human lines, IGF2BP3 marks the fetal programme AND is required for B-ALL survival - the trap is not expression-for-requirement, it is requirement-for-state-maintenance, IKZF3 / Aiolos (Q9UKT9) - the B-lymphoid transcription factor that goes UP under both inhibitors, regulates BCL2, and is a degradable drug target, IMPDH2 - the rate-limiting guanine-nucleotide enzyme whose inhibition lowers LEDGF and menin protein and dismantles the MLL-fusion complex itself, In all 24 read-queue rows inspected, the candidate is the BAIT and this project's protein is the prey - nobody has ever tagged KMT2A, AFF4, menin or PSIP1 and found any of them; plus seven bounded rejections, ING2 - the PHD finger that reads H3K4me3 and turns it into REPRESSION, and whose founding co-crystal is filed under the MOUSE accession, Interactome round 4: what was counted, what was written, what was rejected, and the two alias traps this beat fell into and caught, Interactome round 5: 42 queries, 13 entries written, 9 candidates rejected with counts, and four alias failures of four different kinds, Is the selectivity just pan-essentiality? No: it explains 0.4% of the variance, ITGA4 (CD49d, the alpha-4 of VLA-4) - the niche adhesion subunit with an approved antibody and a 2026 KMT2A-r B-ALL xenograft result, JAZF1 - a 243-residue zinc-finger protein that turned out to be a NuA4 subunit, and the 5' donor of the commonest endometrial-stromal-sarcoma fusion, KANSL1 - the NSL scaffold, and the protein through which WDR5 binding to NSL and to MLL/COMPASS is mutually exclusive, KANSL2 - the second NSL subunit in the WDR5 structure, with one leukaemia record and a dependency profile that is the mirror image of a selective target, KAT7 / HBO1 — an enzyme, a leukaemia-stem-cell dependency, and an inhibitor already in a crystal, KAT8 (MOF) — a genuine KMT2A partner that binds the half of KMT2A the fusion discards, KAT8/MOF sets the quiescence set-point of the blood stem cell - and its catalytic activity is separately required for MLL-AF9 leukaemia, which DepMap also cannot see, KDM1A (LSD1) — acts at the loci the fusion binds, spares normal stem cells, and still has never been shown to touch the fusion protein, KDM2A - the CXXC reader that antagonises KMT2A leukaemogenesis, and displaces wild-type MLL rather than the fusion, KDM2B — 513 potent ChEMBL rows that are mostly patent bins, and no structure of the domain they claim to inhibit, KDM3B - the H3K9me1/2 demethylase that sits on the KMT2A breakpoint cluster region and keeps it from rearranging, and the only leukaemia gene in this graph whose direction of effect flips between the myeloid and the lymphoid literature, KDM4C (JMJD2C/GASC1) — recruited by the retained KMT2A N-terminus, drugged in a KMT2A::AFF1 line, and invisible to CRISPR, KDM5A / JARID1A / RBP2 (P29375, 1,690 aa) - already in this graph as the 3' half of NUP98::KDM5A and never written as a gene: the H3K4 demethylase CTCF recruits to a break, the only ERASER in the licensing cascade, and the one cascade member with no blood-lineage ChIP-seq anywhere, KDM6A / UTX — a commonly asserted KMT2A partner that belongs to a different complex and points the opposite way, KITLG (stem cell factor) - the niche ligand of KIT, zero mentions anywhere in this graph, and its own symbol collides with the SCF ubiquitin ligase this corpus talks about constantly, KMT2A rearrangement creates a requirement for the FA ubiquitin-transfer module — the claim, its prior, and the four results that would kill it, KMT2A-rearranged cells need the factors retained through elongation MORE and the factors ejected at pause release LESS — a six-gene asymmetry nobody has reported, KMT2A::ABI1 (MLL-ABI1), t(10;11)(p11.2;q23) — the partner that binds an elongation partner, KMT2A::AFF1 cells run with more free P-TEFb than other leukaemias - and if they do not, this graph's CDK9 story is about recruitment only, KMT2A::AFF1 needs a developmental window and a lymphoid-committed cell — the cell type is a condition of transformation, not a consequence of it, KMT2A::EPS15 (MLL-AF1p), t(1;11)(p32;q23) — the infant-ALL cytoplasmic partner, KMT2A::SEPTIN11 (MLL-SEPT11) — the fusion that cytogenetically impersonates t(4;11), KMT2A::SEPTIN5 (MLL-SEPT5 / MLL-hCDCrel-1), t(11;22)(q23;q11.2), KMT2B has no haematopoietic cell-state result, and two of the seven records that look like one are about a different gene in muscle, Knock down CDK13 and CDK12 side by side in lineage-matched KMT2A and non-KMT2A lines, and ask whether the DepMap signal is real, LARP7 - the clamp on the 3' end of 7SK, whose human loss-of-function phenotype is dwarfism and intellectual disability rather than cancer, LEDGF/p75 is required in the leukaemic cell and dispensable in ADULT MOUSE HAEMATOPOIESIS - not in the normal organism, which its germline knockout does not survive, LEO1 — the weakest-evidenced entry in the PAF1 complex, and the gene whose Ensembl id this project already got wrong once, LEPR - the marker that defines the SCF-supplying perivascular niche cell, the receptor for an adipocyte signal that blunts cytarabine, and a gene_exact query that returns the wrong protein first, Lineage-split dependency for the round 5 panel: 23 genes, 2 myeloid-identity artefacts caught, and 3 survivors of which one has no literature at all, Lineage-split DepMap: neither USP2 nor MAML2 is a dependency in KMT2A-rearranged lines, and USP22 is, Live DepMap on fourteen genes: CDK6's pan-essentiality is a lineage artefact of pooling, and not one gene of the homeodomain cofactor code is a dependency anywhere, LMO2 (rhombotin-2) - a bridging LIM-only protein, higher in pro-B and MLL-rearranged B-ALL, anti-selective in KMT2A-rearranged lines, and a physical partner of the KDM5A module that NUP98::KDM5A retains, MAML2 (mastermind-like 2) - the Notch co-activator that is a KMT2A partner in leukaemia and in thymoma, MBD1 - one protein with a methyl-CpG reader and three CXXC fingers, only the third of which binds unmethylated CpG, and whose CXXC fails the MLL-AF9 swap, MBTD1 - the H4K20me1/me2 reader inside NuA4/TIP60, the quiescence brake on adult haematopoietic stem cells, and the 3' partner of ZMYND11::MBTD1 whose methyl-lysine cage the fusion carries and does not use, MEAF6 - a 191-residue subunit shared between the NuA4/TIP60 and MOZ/MORF acetyltransferase complexes, whose only two UniProt localisations both cite papers that are not localisation studies, Measure replication stress directly in KMT2A-rearranged cells instead of inferring it from a dependency ranking, Measure the pausing index at KMT2A::AFF1 target genes — the one number the whole pausing argument turns on, and it has never been reported, MECOM (EVI1) - a cell-of-origin memory that MLL-AF9 maintains but cannot install, present in about 43% of MLL-rearranged AML and marking the chemoresistant half, MED12 - a named menin-associated protein that restrains menin's transcriptional output, and the anchor of the CDK8 module a KMT2A-r AML paper co-targets, MED23 — rank 16 of 17,728, survives the lineage split with the B-lineage half stronger, and is not absent from the leukaemia literature after all, MED23 confirmed, and the zero-record claim corrected: it is not literature-free in leukaemia, an shRNA screen already found it, MED26 — a common-essential Mediator subunit with a solved 87-residue domain and no ChEMBL target entity at all, MEF2C — an output-program transcription factor, the second-strongest leukemia co-dependency, and a gene humans cannot spare one copy of, MEIS1 — rate-limiting for MLL leukemia stem cells, a surviving co-dependency, and embryonic-lethal when removed, MEN1, DOT1L and LEDGF dependency in the only CALM-AF10 cell line DepMap has screened, Menin dependence varies 2.83x across KMT2A::AFF1 lines and the spread survives at three donors - but RS4;11 is last on KMT2A itself, so the heterogeneity is largely fusion-dependence heterogeneity, and DAXX is the one gene decoupled from it, Menin has never been tested against SET::NUP214 - a bounded absence in three independent registers: literature, cell-line dependency data, and the founding paper's own blots, MEPCE - absent from this graph until now, and a deeper pan-dependency than BRD4, MLLT1 / ENL — the reader that beat its own paralogue, with a degrader already in hand, MLLT11 / AF1q — a 90-residue protein with no chromatin domain and no oligomerisation module, KMT2A partner in t(1;11)(q21;q23), MLLT3 / AF9 — a famous fusion partner that is not a dependency, and a hub domain that is, MLLT3 runs normal stem-cell self-renewal and is required in essentially no leukaemia line — the inverted case, MLLT6 (AF17) — the fourth KMT2A fusion partner inside DotCom, and the only one no cell needs, MOF/KAT8 is required by both KMT2A::MLLT3 and NUP98::HOXA9 — which is why it is the wrong kind of convergence, MSL1 - the MSL scaffold that carries MOF and MSL2 to HOXA9 and MEIS1, with zero records against KMT2A and a mapped, drawable domain architecture, MSL2 — the second H2B ubiquitin ligase, sitting inside the MOF complex the KMT2A fragment contacts, MTHFD1 (P11586) - the inverse case: the deepest leukaemia dependency in the serine/one-carbon panel, and the drug does not touch it, MTHFD2 (P13995) - the one panel member with a published MLL-AF9 in-vivo survival result, and the serine gene that behaves exactly like an ISR gene, MV4-11 (CVCL_0064) — KMT2A::AFF1, yes, but a ten-year-old's acute monocytic leukaemia with FLT3-ITD, MYB — rank 17 of 17,728 for KMT2A selectivity, and the only node in this beat where partial, transient suppression eradicated leukaemia without stopping normal blood production, MYC - named in a hundred entries of this graph and, until now, written in none, MYO1F — unconventional myosin IF, a KMT2A partner with neither a transactivation domain nor a dimerisation domain, NELF — the brake that has to come off for elongation, absent from the KMT2A literature, and less required in KMT2A-rearranged lines than in any other leukaemia, NELFB (COBRA1) — the NELF scaffold, and the single least KMT2A-selective gene of the sixty least selective in the genome, NELFE (RDBP) — the RNA-binding subunit of the pausing brake, and the alias that inflated a record count fifty-fold before it was caught, None of the five selective unwritten interactors survives a null, and FANCD2 - the one that carried a story - is the second weakest of them at p = 0.12, Nothing beats menin after all, and the statistic that said otherwise ranks narrowness, NPM1 (nucleophosmin) — the nucleolar shuttle whose mutant form binds chromatin with KMT2A and buys the second menin-inhibitor indication, NSD1 - the H3K36 dimethyltransferase whose catalytic activity a NUP98 fusion cannot do without, and which cells can otherwise lose almost for free, NSL complex - the MOF assembly that five NUP98 fusions bind alongside MLL1, and that competes with MLL/COMPASS for WDR5, NUP214 / CAN - the cytoplasmic-face nucleoporin that CRM1 docks against, and the 3' partner of four leukaemia fusions, NUP98 - the mobile nucleoporin that leaves the pore to put H3K4me3 on haematopoietic promoters, and the shared 5' donor of seven fusions in this graph, Of 262 curated interactors this graph never wrote down, five are selectively required in KMT2A-rearranged lines - and one of them is FANCD2, which binds menin and sits inside a selectivity signal this project has failed four times to explain, P-TEFb (CDK9 + cyclin T1) — the deepest dependency and the clearest therapeutic-index wall in the interactome, PAF1 — pan-essential subunit of a complex the fusion needs, where the window is in the interface and not in the protein, PAF1C couples transcription to H2B ubiquitination - but the RTF1 half of that coupling is yeast-specific and contested in human cells, and PAF1C is one of the few complexes that genuinely binds the retained KMT2A fragment, PAF1c is needed by the normal stem cell and by the leukaemia, and the genes it regulates in each are different, Pan-essentiality: checked for all eight, and cleared — but a shallow dependency is its own problem, PBX3 - the TALE cofactor the field says is non-redundant, and the experiment that says HOXA9 is the redundant one, PCGF1 — the PRC1.1 scaffold whose LOSS causes menin-inhibitor resistance, so it is a restraint on the leukaemia rather than a dependency of it, PES1 / pescadillo (O00541) - the missing PeBoW subunit of this graph's nucleolar block, pan-essential in 96.9% of DepMap lines, and the one myeloid experiment on it shows proliferation WITHOUT a differentiation block, Phase-2 dossier: CBX8 - the candidate this review would kill, and the reasons are all numeric, Phase-2 dossier: DOT1L - perfect chemistry, a completed paediatric trial, and a target that has already had its answer, Phase-2 dossier: KAT7/HBO1 - the only enzyme here with a real active site, a co-crystal inhibitor and a co-dependency that survives lineage adjustment almost intact, Phase-2 dossier: the ENL YEATS pocket - two co-crystals, nanomolar chemistry, and a co-dependency that only appears inside leukaemia, Phase-2 dossier: the LEDGF/PSIP1 IBD - the best therapeutic index in the interactome, a solved structure, two hotspot residues, and three compounds in the world, Phase-2 dossier: the menin MBM1 pocket - the only candidate here that is already de-risked, and therefore the only one whose gate is clinical, PHF1 (PCL1) - the PRC2 accessory subunit whose Tudor domain reads H3K36me3, and the 3' acceptor shared by three different NuA4-donor fusions in two different tumour types, PHGDH (O43175) - the largest menin-SELECTIVE fall in the whole serine panel, and the least essential gene in it, PICALM (CALM) - the clathrin-assembly adaptor that is the 5' partner of CALM::AF10, PICALM::MLLT10 (CALM-AF10), t(10;11)(p13;q14) - the DOT1L-dependent HOXA fusion that contains no KMT2A, PLK1 — nominated as an infant-restricted vulnerability, and one of the most essential genes in the genome, PPIE (CyP33) — the off-switch the fusion throws away, and the reason PHD3 reinsertion kills transformation, PRC1.1 — the complex this graph has been leaning on, now enumerated subunit by subunit, and the enumeration changes the conclusion, PRMT1 — an MLL-fusion cofactor whose first-in-human inhibitor was terminated for lack of efficacy and toxicity, PRMT3 - the mostly-cytoplasmic ribosome methyltransferase that also writes the ACTIVATING mark on the residue PRMT5 represses, has an acute-leukaemia degrader, and is invisible to this project's own mark-query rule, PRMT5 - the type II arginine methyltransferase this graph has reached for sixteen times, whose mark on H3R2 RECRUITS WDR5 to chromatin, PRMT6 - the enzyme whose mark is MUTUALLY EXCLUSIVE with the MLL complex on the H3 tail, and which shuts HOX genes down by evicting WDR5, PRMT7 - the enzyme whose class is still disputed, which represses a KMT2 enzyme by writing H4R3me2s, which is required for leukaemia stem cells in CML, and whose only H3R2 claim is the one this beat was dispatched to check, PSAT1 (Q9Y617) - a DIRECT ATF4 target, and the gene that shows the brief's menin-selectivity claim was PHGDH's and not the pathway's, PSIP1 / LEDGF p75 — the tether with the best therapeutic index in the whole interactome, PSPH (P78330) - the third serine-synthesis enzyme, high in Ewing sarcoma alongside PHGDH and PSAT1, and the one that does NOT fall in leukaemia, Put the same fusion in two cell types and degrade it, rather than cutting the gene, RAD50 (Q92878, 1312 aa) - the third MRN subunit, and the one that settles whether the complex is incoherent in DepMap: mean -0.114 with 5.2% of 1,257 lines below -0.5, so it sits with NBN and not with MRE11, yet it covaries with MRE11 across cell lines as tightly as BRCA1 does with BARD1, Ranking every KMT2A::AFF1 partner on dependency versus essentiality, RBBP5 — a WRAD subunit that binds the one part of KMT2A every fusion throws away, REST / NRSF - the transcription factor that delivers G9a to chromatin through MED19 and MED26, is a paediatric cancer gene, and is the worst search token in this corpus, RNF2 (RING1B) — the one catalytic subunit shared by every PRC1 flavour, which is why the genetics point two ways at once, RNF20 (BRE1A) — the H2B ubiquitin ligase that MLL-rearranged leukaemia needs, and that DepMap says every other cancer line needs just as much, RNF40 (BRE1B) — the obligate partner of RNF20, and the one of the pair with a documented link to differentiation and bivalency resolution, RSBN1 / KDM9 (Q5VWQ0) - an H4K20me2/me3 demethylase in the AFF4 proximity record, and the only read-queue partner that is a chromatin enzyme at all, RTF1 — the PAF1C subunit the graph was missing, on a complex that does bind the retained KMT2A fragment, Run the menin inhibitor against CALM-AF10 next to a KMT2A-rearranged control - the missing two-week experiment, Running the HOXA programme is not enough to need menin, RUNX1 — activated by KMT2A::AFF1 and then bound by the reciprocal fusion, in the one published two-oncoprotein circuit in t(4;11), Scoring complexes instead of genes, and the controls disagree with each other (run), SELE (E-selectin) - the vascular-niche chemoresistance receptor with a clinical antagonist, zero KMT2A papers, and a paediatric trial that a company restructuring closed, Separate ncBAF from canonical BAF in KMT2A-rearranged cells: paired degron, paralogue-pair CRISPR, and complex-resolved CUT&RUN, SEPTIN11 (septin-11) — KMT2A fusion partner at 4q21, adjacent to AFF1, SEPTIN2 (septin-2 / NEDD5) — KMT2A fusion partner in t(2;11)(q37;q23), SEPTIN5 (septin-5 / CDCrel-1) — KMT2A fusion partner in t(11;22)(q23;q11.2), SEPTIN6 (septin-6) — cytoskeletal GTPase, KMT2A fusion partner in t(X;11)(q24;q23), SEPTIN9 (septin-9 / MSF) — cytoskeletal GTPase, KMT2A fusion partner in t(11;17)(q23;q25), Sequencing phase 2: the order to do things in, ranked by information per unit cost, SESN2 / sestrin-2 (P58004) - the ISR's exit into mTORC1: a leucine sensor that falls 1.4 log2 under either inhibitor, and the one panel member with a real structural record, SETD1A — a leukemia dependency whose enzyme activity turns out to be dispensable, SETD1B - the COMPASS paralogue round 4 deferred for want of a leukaemia paper, which had already been published: its SET domain sets H3K4me3 breadth and MYC in MLL-rearranged AML, SETDB1 (Q15047, KMT1E/ESET) - the second H3K9me3 writer: it represses the fusion's own targets via the PAF1 complex, it is required in fetal liver HSPCs and in leukaemic stem cells, and it is a broad dependency in half the CRISPR panel - three published directions that do not agree, SGF29 — a SAGA reader with a Tudor pocket, intermediate essentiality, and the best unexploited profile in this beat, SHMT2 (P34897) - the mitochondrial one-carbon step, and the paralogue that rises while it falls is why its loss may not matter, SIAH1 — the E3 ligase that degrades AFF1, and that the reciprocal AF4::KMT2A fusion escapes, SIAH2 — the second AFF1 E3 ligase, reported only alongside SIAH1 and never separated from it, SIRT1 - not a fusion partner, the least required gene in KMT2A-rearranged lines, and the one target here where the direction of the drug is genuinely disputed, Six countermeasures, no head-to-head — so rank their targets: CDK6 is 13th and CDK4 is 16,052nd, Six times the null pool, and the criterion I had been using turns out to be the problem (run), SKP1 — a pan-essential housekeeping adaptor that is also a structural subunit of PRC1.1, which makes it the one PRC1.1 member that can never be a target, SMARCA2 (BRM) - the paralogue nobody measured, and the reason a DepMap rank cannot predict what a BRG1/BRM inhibitor does, SMARCA4 (BRG1) - a tumour suppressor by mutation and a maintenance requirement by knockdown, and in KMT2A-rearranged lines the dependency data say it is not selective at all, SMARCB1 (BAF47/INI1/SNF5) - zero entries, zero mentions and, on the evidence, correctly so: it is lost in primary AML rather than required, SMARCD1 (BAF60A) - rank 59 of 17,728, survives the lineage split, and had never been named in this graph or studied in this disease, SMARCD2 (BAF60B) - named in one KMT2A paper in the whole of PubMed, and the dependency it carries is myeloid identity, not the rearrangement, SPI1 / PU.1 — a myeloid dependency that a KMT2A panel mistakes for its own, SPP1 (osteopontin) - the endosteal matrix protein whose knockdown prolongs survival in MLL-AF9 mice, and the one KMT2A::AFF1-specific paper about it cannot be read, SS18 - a SWI/SNF subunit that is itself a fusion partner in another cancer, and a lineage-independent dependency in KMT2A-rearranged lines, SSRP1 - the small FACT subunit, and the only protein in this beat that binds a confirmed KMT2A-fusion interactor directly (LEDGF/p75, via HMG box to PWWP), STC2 / stanniocalcin-2 (O76061) - the second largest effect in the signature (-4.40 log2), a SECRETED glycoprotein, and its localisation rests on curator inference alone, SUPT16H (SPT16) - the large FACT subunit: pan-essential, an anti-dependency in KMT2A-rearranged lines, and drugged in MLL-r leukaemia by a compound that works through p53, SUPT4H1 (SPT4) — zero papers linking it to KMT2A, and the 138th most KMT2A-selective gene out of 17,728, SUPT5H (SPT5) — the pausing factor the KMT2A field has never studied, and the counted absence that undercuts 'the fusion hijacks pause release', SUV39H1 (O43463, KMT1A) - the H3K9me3 writer: a menin effector whose binding region OVERLAPS the drug pocket at its N-terminus, a tumour suppressor in MLL-AF9 AML, recruited to double-strand breaks by CTCF, and never localised at the KMT2A locus in any cell type, SWI/SNF enumeration for KMT2A-rearranged leukaemia: every subunit searched, every count dated, and what was read and rejected, SWI/SNF split by sub-complex and by lineage: every KMT2A-selective subunit is in the ncBAF module and none is in canonical BAF, TET1 (LCX / CXXC6) - a CXXC reader that is also a KMT2A fusion partner, and whose leukaemic fusion throws its own CXXC domain away, TET2 is NOT a CXXC protein - its CXXC domain is a separate gene, and it is DEPLETED in KMT2A-rearranged AML rather than enriched, TET3 - the CXXC reader whose domain prefers 5-carboxylcytosine, and the only CXXC-family gene ever found mutated in a KMT2A-rearranged cohort, The 82.9% population scored twice as many defect-shaped notes as the same-source one, and reading six of them says the comparison is confounded by our own DepMap numbers, The comparator arm was never screened for pathway-equivalent lesions — and it made us understate our own result, The confounder every previous analysis flagged and none removed, removed (run), The deferred KMT2A partners: what the counts actually are, what was written, what was rejected, and three numbers the previous enumeration got wrong, The dependencies this project keeps failing to see are the buffered ones: paralogue redundancy and guide placement, not absence of biology, The easy null was not the problem, and nothing in 2,018 genes beat menin, The ELL/EAF activation module (ELL2, EAF1, EAF2) — a general elongation stimulator, not a KMT2A-fusion dependency, The entire experimental model space for SET::NUP214 is two cell lines, neither of them in DepMap, with no mouse model found - so every mechanism in this beat is n = 1 or n = 2, The FA core complex does not move together, and that is the strongest argument against reading this as a Fanconi-pathway dependency at all, The Fanconi signal is in both lineage halves, survives the correlation-proof null, and is still there when lineage is held constant, The fusion may reach the H2B ubiquitin mark through MOF-MSL rather than through RNF20/RNF40 — the one configuration in which this layer could be selective, The histone/ribosomal shape in the read queue is three classes, not one - H2BC21 is distinguishable AND essential at -0.70, so neither existing rejection ground reaches it, and HMGA1 is a harder dependency than MEN1 or KMT2A, The LEDGF PWWP–H3K36me nucleosome contact: how the fusion learns its address, The lineage confound, tested: the FA signal is in both halves, the B-lineage half is stronger, and it survives holding lineage constant, The little elongation complex (ELL + ICE1 + ICE2 + ZC3H8) — the other place ELL works, and why ELL's pan-essentiality is probably not about the fusion, The LSD1–GFI1 SNAG interface — a second worked example of drugging an undruggable repressor through its partner, The menin-FANCD2 bridge is dead: it was tested in 2008, the mutation spectra differ, and there is no genetic interaction, The MRN asymmetry adjudicated: RAD50 -0.114 sits with NBN -0.047 and not with MRE11 -0.542, so it is not one subunit against two - and yet MRE11 and RAD50 covary across 1,208 cell lines at r = 0.554, the same as BRCA1 against BARD1, against a background of zero, The phase-2 go/no-go register: the numbers we agree to before we look, The serine/one-carbon arm is NOT a pure ATF4 output: it is menin-selective where the ISR arm is compound-independent (median margin -0.55 vs -0.02, p=0.011), and it is ABSENT in KMT2A::MLLT3 AML where the ISR arm is present, The serine/one-carbon programme has a SECOND, chromatin-proximal menin input that is not ATF4 - which is why PHGDH is menin-selective where CHAC1 is not, and why the arm is absent in KMT2A::MLLT3, The six open read-queue members split three rejected and three earning entries - and the flattest dependency in the set, ASB7, turns out to be a negative regulator of H3K9me3 via SUV39H1 degradation, The stricter null, and it partly reverses the last one (run), The SWI/SNF dependency in KMT2A-rearranged leukaemia belongs to ncBAF, not to canonical BAF - and the drug in the clinic is aimed at the wrong module, The transcriptional CDK with a real KMT2A-rearranged selectivity signal is CDK13, not CDK9 - and nobody has looked, The whole protein-coding genome: menin is still first, and a metabolic pathway appears (run), The within-donor null: MEN1 sits at the 99.4th percentile of variation between two sublines of ONE child, and at the 98.9th between donors - menin dependence is not heterogeneous between patients so much as unstable in this background, TOP3B (O95985) - the only human topoisomerase that works on RNA as well as DNA, delivered to the MYC promoter by an arginine mark, and it has poisons, TRIB3 / TRB3 (Q96RU7) - a pseudokinase that is the ISR's own brake, falls 3.1 log2 under either inhibitor, and has a published physical link to the MLL complex in the wrong tissue, TRRAP — a 3,859-residue DotCom subunit that every cell needs and no KMT2A cell needs more, Two of the three top new dependencies are myeloid identity, not KMT2A, Two published ways a fusion oncoprotein engages BAF - be a subunit, or recruit it with a disordered domain - and KMT2A has never been tested for either, UBE2A (RAD6A) — the E2 for H2B ubiquitination in one primary account, contradicted by another, and with no KMT2A literature at all, UBE2T — E2; rank 33 of 8,269 for KMT2A-selective dependency, and no KMT2A literature at all, UROS: searched and empty — the scan's rank-15 hit has no leukemia literature, and no entry was written, USP2 (ubiquitin carboxyl-terminal hydrolase 2) - the ninth commonest KMT2A partner and the only one that is a deubiquitinase, USP22 — a KMT2A-rearranged dependency that works through MEIS1 protein stability, and is not an interactor of the fusion, USP8 (UBPY) - the second deubiquitinase KMT2A partner, three patients, same UCH logic, VCAM1 - the stromal counter-receptor for VLA-4, and in MLL-fusion AML its UPREGULATION is anti-leukaemic, which is the opposite of the expected sign, Verdict: 'eleven cell lines, none infant-derived' is right about the screen and wrong about the material — at least ten infant KMT2A::AFF1 lines exist, WAC — the adaptor that hands RNF20/RNF40 to RNA polymerase II, and the only member of this axis whose knockdown alone killed MLL-rearranged ALL cells, WDR5 — the partner that is not a partner: it binds the half of KMT2A the fusion throws away, WDR5 is partitioned, not shared: NSL and SET1/MLL complexes compete for one pool, so perturbing NSL changes how much WDR5 reaches the wild-type KMT2A complex the fusion depends on, WDR5 maintains a differentiation block — in CEBPA p30 AML, not in KMT2A-rearranged disease, and a title check nearly buried it, WDR5: an established wild-type KMT2A contact, and no fusion contact ever measured, What this beat looked at and did not write: rejected candidates, with counts for both halves of every search, Which leukemia co-dependencies survive uncertainty? (run, with p-values), WRAD reaches KMT2A fusions only as a passenger on a recruited wild-type complex, YWHAG / 14-3-3 gamma (P61981) - the only cross-laboratory reproduced KMT2A proximity partner in the curated record, and UniProt places it nowhere near the nucleus, ZEB2 — an EMT transcription factor that turns out to be a leukemia dependency and a guardian of lineage fidelity, ZEB2 level sets how easily a KMT2A-rearranged blast can change lineage under CD19-directed pressure, ZFP64 — rank 4 on selectivity, and there is not even a ChEMBL entry for it

It is not: 3 of 4 read were correctly scoped, the scoping is done in prose, and 39 of 40 flagged entries carry no machine-readable scope, Only 20% of this corpus's absences carry a machine-readable query, which I nearly published as an auditability crisis - and then read five of the other 80% and found every one bounded by a better instrument, The absence-class checker globbed a filename instead of the field, so it walked 40 of 243 entries and reported them as the whole population - and the 40 it called invalid turn out to be two independently re-invented vocabularies, The unbiased half of the token audit: 0 of 15 never-measured tokens are wrong, the entries my filters could NOT see are the best-scoped ones, and two scoping fields already existed that I had claimed to add

    used by 0.2% of profiled sarcomas, median age 38, and every number here has a denominator that is not the population, AF10/MLLT10 fusions drive aberrant self-renewal of non-stem progenitors — found only by opening the paper, AFF4 has never been placed in a haematopoietic cell state — every SEC cell-state result is in another tissue, ANP32E - the eviction chaperone: the only protein in this beat whose job is to take a histone variant OUT of chromatin, ASF1B - the paralogue that actually does the work in blood: it occupies >70% of H3.3 nucleosomes in fetal liver while HIRA is dispensable there, ASH2L is studied in leukaemia and has never been placed in a cell state there — and the KMT2A-rearranged arm needs it LESS than average, ASH2L: the only WRAD subunit ever perturbed in a KMT2A::AFF1 cell, once, weakly, Ask whether the childhood AML in the KDM3B-haploinsufficiency syndrome cohort carried a KMT2A rearrangement - the one human test this mechanism has, and it is a records request, ATF3 (P18847) - the one cascade member the DOT1L inhibitor hits HARDER than the menin inhibitor, and a transcriptional REPRESSOR being counted as a stress output, ATF4 / CREB2 (P18848) - the hub this graph inferred from its targets and never wrote, and its own transcript does not move under either menin inhibitor, ATF5 / ATFX (Q9Y2D1) - the most reproducible repression in the earlier dataset, and the three probe values the graph quotes are SEM, not RS4;11, ATRX - DAXX's partner and the other arm of H3.3 deposition; in this disease its only signal is in the four lymphoid cell lines, CHAC1 / BOTCH (Q9BUX1) - the largest single effect in the whole menin-inhibitor response (-5.11 log2) and a glutathione-degrading pro-apoptotic enzyme, named nowhere in this graph until now, CHAF1A (CAF-1 p150) - the subunit that reads PCNA and makes histone deposition replication-coupled, and the half of CAF-1 that leukaemia has not looked at, DAXX - the strongest of five selective dependencies among 254 unwritten interactors but it FAILS Bonferroni correction (p=0.0128, rank 4 of 254), and not one paper connects it to this disease, DDIT3 / CHOP (P35638) - the cascade's middle node, and the symbol whose two reviewed human records and 16,893-record alias are the worst identifier trap in this beat, DEK - a chromatin architectural protein that gatekeeps H3.3 and boosts HP1alpha, is a fusion partner in its own right, and is the substrate behind this graph's third CK2 route, Does a menin inhibitor create a BMI1 dependency? A two-arm knockout-under-drug experiment in KMT2A::AFF1 cells, with the CDKN2A readout that decides the mechanism, Does KMT2A::AFF1 change histone turnover at its target genes, or does it read a chromatin state it did not make?, DPY30: the founding negative does not cover it, and it has no KMT2A contact to lose, EHMT2 / G9a - the H3K9me1/2 writer that sets whether the KMT2A LOCUS ITSELF rearranges, and whose loss delays MLL-AF9 AML in a supplementary figure nobody can find, EIF2AK3 / PERK (Q9NZJ5) - the kinase whose transcript is flat under both inhibitors, whose arm IS functionally required in MLL-AF9 leukaemia stem cells, and whose common name collides with phospho-ERK, EIF2AK4 / GCN2 (Q9P2K8) - the amino-acid-sensing eIF2alpha kinase: transcript flat, and NOTHING has ever been published about it in any KMT2A-rearranged system under either name, ELL has never been placed in a cell state — its entire leukaemia state literature is its own fusion transcript used as a residual-disease marker, ENL is the highest-expressed target in cerebellum and nobody has studied it there, Enumerating the WRAD-versus-KMT2A-fusion literature: what was searched, found, rejected and could not be read, Every published KMT2A partner in sarcoma, counted - plus the papers this beat read and did not use, so the next beat does not repeat the search without the decisions, FLT3 is the second largest KMT2A-selective dependency and it is HEAVIER in B-lineage than in myeloid cells, Giving the reopening conditions an owner, and the first run changes two decisions (run), H2A.Z - two genes of identical length, one KMT2A paper, and the measured quantity is a ratio nobody has repeated, H3.3 - the graph's most-named epigenetic object with no entry, 325 mentions, and not one measurement in a KMT2A-rearranged cell, H3K27ac - named in 40 entries with no entry of its own, and the strongest KMT2A::AFF1 measurement of it is invisible to every abstract search, H3K4me2 - the LSD1 substrate, and the only histone mark ever compared head-to-head between two KMT2A fusion partners in human cells, H3K9me1 - the only H3K9 state whose level at the KMT2A breakpoint cluster region has ever been measured, and it is LOW there until KDM3B is removed, H3K9me2 - named sixty times in this graph with no entry of its own, the mark that defines the lamina-associated domains the fusion's targets sit beside, and the only H3K9 methylation state ever measured at a KMT2A fusion's own binding sites, H3K9me3 - measured in KMT2A::AFF1 cells, in a supplementary figure, and it rises GENERALLY where H3K27ac falls SPECIFICALLY in the same experiment, H4K16ac - the one mark rule 80 actually rescued in this beat: elevated at MLL-AF9 targets in a supplementary figure, and the reason MLL1's own enzyme turns out to be dispensable, HIRA - the chaperone that puts new H3.3 into transcribed gene bodies, and therefore the machine that runs this graph's clearance clock, Histone H3.3 - one protein, two genes, and the reason this graph should not file it as gene-h3f3a, IKZF3 / Aiolos (Q9UKT9) - the B-lymphoid transcription factor that goes UP under both inhibitors, regulates BCL2, and is a degradable drug target, ING2 - the PHD finger that reads H3K4me3 and turns it into REPRESSION, and whose founding co-crystal is filed under the MOUSE accession, JMJD1C / KDM3C - named in three entries of this graph as one of the only loci that loses fusion occupancy under a menin inhibitor, ranked 23rd of 17,728 for KMT2A-selective dependency in this project's own scan, with the strongest published shRNA effect in SEM - and no entry until now, KAT8/MOF sets the quiescence set-point of the blood stem cell - and its catalytic activity is separately required for MLL-AF9 leukaemia, which DepMap also cannot see, KDM3B - the H3K9me1/2 demethylase that sits on the KMT2A breakpoint cluster region and keeps it from rearranging, and the only leukaemia gene in this graph whose direction of effect flips between the myeloid and the lymphoid literature, KDM6B (JMJD3) - UTX's paralogue, which this graph has argued about for cycles without writing, KMT2B (MLL2/MLL4) - the other protein menin binds, and the one this graph never wrote, KMT2B has no haematopoietic cell-state result, and two of the seven records that look like one are about a different gene in muscle, LEDGF/p75 is required in the leukaemic cell and dispensable in ADULT MOUSE HAEMATOPOIESIS - not in the normal organism, which its germline knockout does not survive, MLL2 and MLL4 each name two different genes, and the ambiguity is in the papers, not in the databases, Niche biology HAS been measured in KMT2A-rearranged disease - but in the index fusion itself there is essentially one marrow-niche molecular experiment, from 2011, Niche proteins enumerated and NOT written in this tranche, and four symbol traps measured while doing it - three of them new to the registry, No H3K9me3 writer and no H3K9me3 reader has ever been localised at the KMT2A locus IN THE PUBLISHED LITERATURE, in any cell type: 20 queries, 5 alias spellings, 0 on-topic records - and CORRECTED 2026-09-22: the SUV39H1 half is no longer unanswerable from archives. ENCODE still holds zero SUV39H1 experiments (verified by three routes with controls), but GEO holds two deposits, and Q114 read both at this locus and found the writer ABSENT, No menin inhibitor has ever enrolled a KMT2A-rearranged solid tumour, and the one solid-tumour menin trial that read out was terminated for lack of efficacy, No proximity, degron or tiling-CRISPR study has ever been run on WRAD in KMT2A-fusion leukaemia, Nobody has ever asked whether a KMT2A-rearranged sarcoma needs menin: zero records, and the reason is that no model exists, One blot: phospho-eIF2alpha and ATF4 protein in RS4;11 under VTP-50469, with a dose-response and a DOT1L comparator arm, PAF1c is needed by the normal stem cell and by the leukaemia, and the genes it regulates in each are different, PPIL4 - a spliceosomal cyclophilin whose BioID neighbourhood is the widest overlap with this graph's subject matter of any bait, PPP1R15A / GADD34 (O75807) - the eIF2alpha phosphatase adaptor, and KMT2A fusion proteins were shown to BIND it and block its apoptosis in 1999, a paper this graph has never cited, PRMT3 - the mostly-cytoplasmic ribosome methyltransferase that also writes the ACTIVATING mark on the residue PRMT5 represses, has an acute-leukaemia degrader, and is invisible to this project's own mark-query rule, PRMT5 - the type II arginine methyltransferase this graph has reached for sixteen times, whose mark on H3R2 RECRUITS WDR5 to chromatin, PRMT6 - the enzyme whose mark is MUTUALLY EXCLUSIVE with the MLL complex on the H3 tail, and which shuts HOX genes down by evicting WDR5, RAD51 - the one repair protein measured AT the KMT2A translocation hotspot, and ATM controls how much of it loads there, RBBP5: the thinnest fusion literature of the four subunits, and one chromatin datum, RBM15 — m6A adaptor, AMKL fusion partner, and a named hit in the only KMT2A-biased RNA-protein CRISPR screen, Re-ran this corpus's literature bounds against the live index: 40 of 40 stored zeros still return zero, none has expired - and 19 stored 'queries' abbreviate their own clauses, so they were never runnable bounds at all, REST / NRSF - the transcription factor that delivers G9a to chromatin through MED19 and MED26, is a paediatric cancer gene, and is the worst search token in this corpus, Rule 80 measured: the abstract index missed the best KMT2A measurement for three marks out of seven, and confirmed the absence for the other four, SELE (E-selectin) - the vascular-niche chemoresistance receptor with a clinical antagonist, zero KMT2A papers, and a paediatric trial that a company restructuring closed, SEPTIN2 (septin-2 / NEDD5) — KMT2A fusion partner in t(2;11)(q37;q23), SESN2 / sestrin-2 (P58004) - the ISR's exit into mTORC1: a leucine sensor that falls 1.4 log2 under either inhibitor, and the one panel member with a real structural record, SET / TAF-I beta - a histone chaperone that binds the retained N-terminus of MLL, co-activates HOXA with it, and is itself a HOXA-activating fusion partner that recruits DOT1L, SGF29 — a SAGA reader with a Tudor pocket, intermediate essentiality, and the best unexploited profile in this beat, SGK1 / SGK (O00141) - a MENIN-SELECTIVE upregulated kinase, a druggable AGC family member, and the panel's worst platform disagreement, SKIC8 (formerly WDR61) — the last PAF1C subunit, and a gene-symbol trap worth recording, SMARCB1 (BAF47/INI1/SNF5) - zero entries, zero mentions and, on the evidence, correctly so: it is lost in primary AML rather than required, SMARCD1 (BAF60A) - rank 59 of 17,728, survives the lineage split, and had never been named in this graph or studied in this disease, SMC3 - the cohesin ATPase arm, the only subunit whose partial loss has been tested directly against a KMT2A fusion, and it was tolerated, SOCS2 (O14508) - a MENIN-INHIBITOR-SELECTIVE member of the signature, a cullin-5 E3 substrate receptor, and its likeliest upstream regulator is MEF2C rather than ATF4, SPI1 / PU.1 — a myeloid dependency that a KMT2A panel mistakes for its own, SRCAP - the other H2A.Z-loading motor, whose entire PubMed intersection with MLL is five neurodevelopmental gene panels, STC2 / stanniocalcin-2 (O76061) - the second largest effect in the signature (-4.40 log2), a SECRETED glycoprotein, and its localisation rests on curator inference alone, SUMO1 - not a complex partner of LEDGF but a modifier of it, and the interactome row cannot tell you which, SUPT6H (SPT6) - the histone chaperone that rides with RNA polymerase II, which puts it closer to the fusion's proposed mechanism than anything else in this beat, The clearance clock has machinery, and the machinery says the clock does NOT stop in a non-dividing cell - a postmitotic heart replaces its histones with a half-life of about two weeks, The druggable node in the homeodomain code is the MEIS1-PBX3 interface, not the HOX-PBX one - and it is the only one nobody has attacked, The H3K9me1/2-CTCF brake: a KDM3B-G9a balance keeps the KMT2A breakpoint cluster region methyl-poor and CTCF-bound, and losing either end makes the locus amplify and rearrange - in epithelium, in primary cord-blood progenitors and in mice, The KMT2-family beat's own ledger: every query run, every gene dropped, every paper read and not used, The leukaemia term hid the answer for DPY30 — a rule-77 demonstration with clean rule-67 controls, TRIB3 / TRB3 (Q96RU7) - a pseudokinase that is the ISR's own brake, falls 3.1 log2 under either inhibitor, and has a published physical link to the MLL complex in the wrong tissue, UNC0642 - the G9a/GLP chemical probe that abolished doxorubicin-induced Kmt2a copy gain in mice, and the one intervention in this beat that has been given to an animal, USP1: an inhibitor, activity in B-ALL, and zero papers in the disease we care about, WDR5 maintains a differentiation block — in CEBPA p30 AML, not in KMT2A-rearranged disease, and a title check nearly buried it, WDR5: an established wild-type KMT2A contact, and no fusion contact ever measured, What the CTCF-protects paper actually cites: it names Gothe and Atkin in ONE direction-free sentence and declares the direction unresolved, and the two papers that ran the reciprocal experiment are absent from all 81 of its references

    used by 22 of the 37 promoters in the published B-ALL-specific peak class are the clustered protocadherin gamma locus - one 23.8 kb interval at chr5:141,473,710-141,497,491 - and it reads below an average promoter in all 27 samples, A uniform permutation null and a coverability-matched one disagreed on 18 of 23 samples for the same gene set - the null, not the data, decided the verdict, A73051 has the lowest oncoprotein share of the 25 untreated samples, and its sequencing depth is mid-range (37th-39th percentile), so the reading is not a depth artefact - the coordinator's cycle-135 qualification misidentified enrichment as coverage and was reversed in cycle 138, Hypothesis: the HOXA-negative, IRX1-negative KMT2A-rearranged blast is a low-oncoprotein-dosage state, not a state whose oncoprotein has been redirected to another programme, My own pre-registered reagent gate was the wrong test: it demanded a within-sample ordering from a class defined by a between-sample difference, and it failed by 2.5%, Spike-in-normalised paired KMT2A N- and C-terminal CUT&RUN, with a fusion-junction readout, in a HOXA-negative KMT2A-rearranged blast beside a HOXA-positive one from the same institution and batch, TB920488, the other HOXA-negative IRX1-negative blast, has the highest GMP-over-B-lineage ratio of any B-lineage sample in the deposit - and it fails both the matched null and the N-over-C test, The AML-over-ALL retention ratio is 93.5% denominator: the GMP-like numerator barely moves across 23 samples while the B-lineage denominator varies fourteenfold, so the ratio measures loss of the B-lineage class and not gain of the GMP-like one, The GMP-like peak class is fusion-enriched in exactly one of GSE252378's 27 KMT2A-rearranged samples - p318, the sample it was derived from - once the null is matched on how coverable those promoters generically are, The GMP-like promoter class carries no N-over-C excess in 25 of GSE252378's 27 samples: whatever occupies it is seen equally by the fusion-side and the wild-type-side antibody, The GMP-like state is being used as a therapeutic anchor in two independent arguments, and its chromatin definition rests on one post-lineage-switch sample that also defined it, The GMP-over-B-lineage occupancy contrast tracks the sample's own lineage - and institution, which is the identical split in this deposit - and not its HOXA status, The pre-registered three-branch test of 'the HOXA-negative blast's oncoprotein is on the GMP programme' returns NEITHER/UNINFORMATIVE, on four independent gates, The published peak classes do transfer from 20 kb peaks to 2 kb promoters - the GMP-over-B-lineage ratio swings 8.56-fold across the pair that defined them - but only in the between-sample direction the classes were built in

    used by A cell that cannot deposit H2AK119ub is still evicted normally by a menin inhibitor and silences its vacated sites less - so a fusion-occupancy pharmacodynamic marker reads FULL ENGAGEMENT in exactly the genotype that responds worst, and this is now the fourth independent reason this corpus distrusts its own candidate markers, A ChIP-seq series of 158 samples that names no antibody anywhere in its metadata: the string 'antibod' occurs ZERO times in GSE260742's 419,824-character SOFT dump, and the reagents are in a supplementary spreadsheet the full text never quotes, A DOT1L inhibitor DOUBLES H3K79me2's mid-occupancy share (1.89-2.01) and a menin inhibitor CUTS it (0.69-0.78), in THREE murine samples one of which is a replicate (corrected cycle 97; the id still says four) with no overlap between the ranges, while the FLAG and MLL1-N channels sit at 0.905-0.929 under both drugs - so the two drugs do not act on one axis and 'a fraction of the achievable effect' presumes they do, A menin inhibitor's chromatin signature is organised by how much fusion it removed from each site, so every mark's response is a GRADIENT in eviction depth - and any readout that averages over a fusion-occupancy set is underpowered by construction, sometimes to exactly 1.000, A PCGF1-null cell - a published resistance genotype - loses H3K79me2 at the most-evicted sites exactly as a control cell does (0.6123 against 0.5860), so the new stratified readout scores it as fully drug-engaged, and stratification does NOT close the resistance blind spot it was hoped to close, A plateau criterion of the form 'the last interval contributes at most 10% of the total' fires when the last interval is NEGATIVE, so it reports a plateau for a series that reversed - and the guard that caught it was a separate monotonicity check written for a different reason, A Spearman over four quartiles has 24 orderings and 11 attainable values: rho = +1.000 is 1/24 = 0.042, |rho| = 1.000 is 2/24 = 0.083, and a +-20% band around 0.80 contains exactly one attainable value - so a perfect monotone over four strata is a weak statistic and must never be scored alone, Across eight murine contrasts and two human stratifications, the H3K79me2 eviction span separates a menin inhibitor from a DOT1L inhibitor 22-fold with no overlap AND detects menin engagement in a human cell whose aggregate reads 0.998 - two properties the aggregate has one of and one of, Across every same-condition H2AK119ub replicate pair in GSE260742 - nine pairs, three arms, both pairing shapes - rank concordance over the shared bin universe runs 0.6481 to 0.8796 and never reaches 0.88. The floors this thread scores against are all computed from pairs that are only moderately concordant., Across four VTP timepoints the within-sample share at a fixed top-0.1% set ranks perfectly inversely to the track's non-zero bin count (Spearman -1.000 over a 2.2-fold spread), so this project's standard instrument is confounded with ChIP enrichment - and the confound cannot be removed from inside one sample, All four input samples explicitly titled to the MLLAF9 ChIP arm of GSE260742 carry supplementary_file = NONE, so no input-referenced peak call is possible from the processed deposit - and the only deposited batch-1 inputs are two BAMs filed under a different arm's title with the same cell line and the same F3 filename prefix, All four murine VTP-50469 H3K79me2 contrasts in GSE260742 give Spearman -1.000 against eviction depth, and all four SGC0946 contrasts are flat: the sign reproduces four times out of four, the span only to within a factor of 1.99, and the replicate pair that establishes this was already binned on disk from cycle 82, Asked for the first time whether a KMT2A fusion GAINS chromatin sites under a menin inhibitor: all three pre-registered criteria fire, and the set they fire on is 52 low-amplitude bins reaching 6x the genome median, 16 of them with no gene within 20 kb and 1 of 52 on a CpG island where 66% of the fusion's real sites are, At the 2 kb bins a menin inhibitor strips the most fusion from, both repressive marks GAIN and the active mark is LOST, monotonically in eviction depth (Spearman +1.000, +1.000 and -1.000) against a baseline-matched null that is flat to within 0.007 - the silencing clause of hyp-q117's prediction 5, measured for the first time, Bin the deposited H2AK119ub NTvKO 2 x 3 design: twelve files, three replicate conventions, public since 2025-11-23 and never analysed - it is the only route to the silencing clause of hyp-q117's prediction 5, it is the internal validation of the PCGF1 knockout this project's null depends on, and it carries a spread the H3K79me2 arm cannot, Both datasets this beat used carry an exposure mismatch that could have produced its results, and both were measured rather than argued away: MOLM13's MENIN pair is 4 days against everything else's 3, and GSE260742's VTP arms are 48 h against 72 h DMSO controls - the first moves a criterion by 0.024 and the second is matched between the two arms being compared, Cycle 107's headline same-condition floor of 3.03% at D1 is a median over a MIXED population of two genotypes. Restricted to the non-targeting control genotype it is 10.49%, so the borrowed 10% floor cycle 107 declared 'too generous by 3.3x' was in fact about right there - cycle 107's own F2, not its F1., Download and bin GSE127507's nine RS4;11 tracks (1.99 GB), rebuild a human binner, and score the eviction gradient in the index fusion KMT2A::AFF1 - the one measurement that would move this finding from KMT2A::MLLT3 to the disease this graph is about, Every chromatin readout of a menin inhibitor measured in this corpus is graded by how much fusion the drug removed from a site, so a within-sample average over the fusion's occupancy set is the wrong statistic and will report near-null in a responding cell - the signal is the SLOPE against eviction depth, not the level, Every noise floor in this thread is computed from within-sample shares, which sum to one. A purely local change therefore leaks into every other stratum by arithmetic, so no floor measured this way can distinguish 'the bulk moved' from 'the peaks moved and the shares renormalised'. A tighter floor is not thereby a cleaner one., Four matched input tracks, used for the two things an input is actually for: no chromosome-scale copy-number difference between the CRISPR clone and its control (max 1.0988, min 0.9470 in both processing states), and the knockout's H2AK119ub depletion from CpG islands is REAL because its own genomic DNA is enriched there, not depleted, GSE260742 declares an H3K27me3 second channel in its MLLAF9 Control arm, and no floor can be computed from it: all three rep1/rep2 pairs agree about only 86.31-88.90% of the shallower track's covered bins, so 11-14% of the SHALLOWER track's coverage falls where the DEEPER one has none. Depth cannot explain that., GSE260742's murine H3K79me2 samples come from FOUR distinct cultures - F3, F3_NT, NT and the PCGF1-KO clone C1 - and the titles name only two of the distinctions; 'Timecourse Control' is the F3 line, and 'NTvKO Control' covers two different filename families that are not the same material, GSE260742's PCGF1-knockout samples carry no deposited measurement of PCGF1 - no protein, no transcript, no sequencing of the edited locus - and the knockout rests on one guide and one clone with no rescue, so every null result from that arm is a null in an unverified genotype, GSE260742's VTP-50469 kinetic series carries no SGC0946 sample at any timepoint, so the denominator of F cannot be measured inside that batch and the fraction cannot be recomputed at any time - the only SGC0946 arms in the series are in different experiments at a single 72-hour or 7-day exposure, GSM8123377 and GSM8123403 carry the same supplementary filename but for the `.filt.bam` marker, yet GEO titles one 'MLLAF9 Control - DMSO H2AK119ub rep2' and the other 'NTvKO Control - DMSO H2AK119ub paired'. Scored directly, they are DIFFERENT libraries (Spearman 0.83), so the collision is a naming accident and both arm titles stand., GSM8123386/387/388 carry the GEO title 'MLLAF9 Control - ... H3K79me2 rep2' and the supplementary filename 'ChIP_K79_F3_NT_*'. Two committed analyses treat them as a separate culture and one asserts 'FOUR INDEPENDENT MURINE CULTURES'. If the titles are right there are three, one of them replicated. REPORTED AS A DISPUTE, NOT APPLIED., GSM8123405 is mm10 DATA in an hg38-DECLARED TDF - the exact mirror of Q122's mm10-declared / hg38-coordinate defect, in the same series - and the container silently clipped 72.8 Mb (2.76%) of chr13-chr19 and chrX at deposition; the declared extents name the container and max_end names the data, H3K4me3 is the one mark in GSE260742 with no declared second channel at all - six samples, no replicate suffix anywhere - so no same-condition pairing exists and its noise floor remains a transfer from another mark whatever else is measured., H3K79me2 reports only the DOT1L arm of a menin inhibitor's action and is blind to its PRC1.1 arm - so the mark's response is unchanged in a PCGF1 knockout even though PCGF1 loss is a published resistance mechanism, and a cell resistant through PRC1.1 loss would look fully drug-engaged by this readout, hyp-q117's prediction 5 is stored TWICE in one entry, in sections[0].body_md and in data.predictions[4], and the two strings differ - here is the scored outcome and the ALL-CAPS cashed text proposed for both locations, with the clause-by-clause verdict a one-line 'confirmed' would have hidden, hyp-q117's prediction 5 says 'in a PCGF1 OR BCOR knockout' and GSE260742's only genetic perturbation is the PCGF1 knockout: across all 158 sample records the strings BCOR, BCORL1, KDM2B, RING1 and RNF2 appear zero times as a perturbation, so a verdict on PCGF1 is not a verdict on the prediction as written, Hypothesis: the same-condition floor measured this way is largely a property of where the EXTERNAL stratifier puts its top bins relative to each library's own coverage, not of how well the two replicates agree - which would explain a twentyfold arm span sitting on top of rank concordances that barely differ., In a PCGF1-knockout clone the menin inhibitor still evicts and the vacated sites are still silenced, but LESS: H2AK119ub at the most-evicted quartile falls from 1.4450 to 1.1325 and from 1.0151 to 0.8842 in two replicate conventions, and H3K27me3 from 2.0007 to 1.0134 - so prediction 5's silencing clause is directionally right and quantitatively overstated, In human MOLM13, DOT1L's own occupancy under a menin inhibitor runs 0.1364 / 0.3083 / 0.3555 / 0.3913 across MLL1-N eviction-depth quartiles at Spearman -1.000 - the writer is lost in proportion to eviction depth, and its mark follows with a 2.9-fold smaller span, In MOLM13, human KMT2A::MLLT3, from the VTP-50469 founding paper's own series GSE127507, H3K79me2's aggregate response at MLL1-N's top sites is 0.998 - and the same sites split by eviction depth run 0.7746 / 1.0601 / 1.0995 / 1.1421 at Spearman -1.000, with the INPUT stratified identically staying flat, In murine MLL-AF9, H3K79me2's response to a menin inhibitor runs 0.586 / 0.819 / 0.928 / 1.187 across the four eviction-depth quartiles of the fusion's own top-0.1% sites - Spearman -1.000, span 0.6005, the largest of any mark measured in these bins except H3K27me3 - while the aggregate over the same 1,228 bins is a single unremarkable 0.8156, In murine MLL-AF9, knocking out PCGF1 changes the menin inhibitor's effect on H3K79me2 by 0.0166 of a share ratio and the DOT1L inhibitor's by 0.0101 - both smaller than the 0.0584 two control cultures of the same line already differ by, so the mark's drug response runs outside PRC1.1, In the only system where the fusion can be measured separately, a menin inhibitor removes MLL1 from wild-type-dominated sites harder than it removes the tagged fusion from its own sites - 0.1069 against 0.1793 - which is an on-target effect on normal KMT2A-menin complexes and an argument about toxicity nobody in this project has made from occupancy data, In the VTP-50469 timecourse Q124 declared uninterpretable, the eviction-gradient SPAN grows monotonically 0.104 / 0.198 / 0.214 / 0.335 at 4/8/16/24 h with Spearman -1.000 at every timepoint - while the aggregate it was suppressed for is non-monotone and perfectly anti-correlated with library complexity. The span is better behaved, and it is NOT clean., Menin inhibition removes the fusion from its strongest sites without relocating it to a new programme, and PRC1.1 fills in only where the eviction is complete - so the drug's chromatin action is subtraction plus local substitution, not redistribution, No washout, withdrawal, release or drug-removal sample exists in any of GSE260742's 158 records, so the third clause of hyp-q117's prediction 5 - that the programme returns on drug withdrawal - cannot be scored from the deposit that prediction names, and closing it needs a wet experiment rather than a download, Pre-registration protects against moving the goalposts and does not protect against this: a blacklist added to fix an unrelated artefact moved a pre-registered count from 42 to 52 across a threshold of 50, flipping the verdict from FAIL to PASS without anyone touching the threshold, Prediction 5 of hyp-q117 contains three separable claims - normal eviction, no silencing, and return on withdrawal - and the deposit it names supports one of them only through a clause it never states; the eviction and silencing clauses need tracks the NTvKO arm does not carry, and withdrawal is absent from all 158 samples, Q117's prediction, run: an MLL1 N-terminal ChIP and a FLAG ChIP of the tagged fusion in the same murine cells diverge 1.83-fold at Myb (0.6645 against 0.3623) and agree to within 4% at Meis1 (0.112 against 0.1171) - the direction is exactly as predicted and the pre-registered numeric threshold for Myb still fails, Q124's criterion H2 was written to be able to void Q124's own conclusion, and it cannot - because it is scored on a contrast in which the control genotype shows no effect to lose. Its raw arithmetic FIRES at 0.0813 against a 0.05 threshold, which reads as 'the knockout is a knockout' and is not evidence of anything, Re-score all nine GSE260742 same-condition floors under two further external stratifiers already binned on disk - KDM2B DMSO and the Oct-2024 input - to decide whether the twentyfold arm span is a property of the replicate pairs or of the stratum definition. Zero downloads, one re-run of an existing script., Re-score every committed within-sample share ratio at S_FLAG against Q117's eviction quartiles - the bins are already on disk in five scratch directories, no download and no wet work - and start with the H3K79me2 PCGF1 arm, because cycle 83's central null is the one most likely to change, RS4;11 - the human KMT2A::AFF1 index-fusion line - has a deposited H3K79me2 pair, a MENIN pair, an MLL1-N pair, a DOT1L pair and an input under the same menin inhibitor in GSE127507. Every track needed to run this beat's test on the index fusion exists. The download is 1.99 GB measured by HEAD request, and nobody has run it., SGC0946 removes 86% of H3K79me2's share at the fusion's own sites and the four eviction quartiles are 0.1396 / 0.1453 / 0.1452 / 0.1360 - span 0.0036, Spearman +0.400, a bootstrap interval spanning zero - so a very large effect on this mark can carry no eviction-depth structure whatever, Six GSE260742 samples titled 'NTvKO ... H2AK119ub rep1' carry ChIP_FLAG filenames AND a ChIP_FLAG string in the TDF header their own depositors' igvtools wrote - two of three independent sources say FLAG, the shape test is near-indecisive, and the channel of half the replicate arm cannot be settled from the deposit, Stratifying by eviction depth does NOT rescue H3K79me2 as a resistance-detecting readout: at the most-evicted quartile the PCGF1-knockout and the control are 0.6123 against 0.5860, a difference of 0.0263, while the whole genotype effect sits at the LEAST-evicted quartile (-0.1401) - the opposite of eviction-graded, Tested in an independent deposit with an epitope-tagged fusion: of the pivotal paper's three named losers under a menin inhibitor, MEIS1 and JMJD1C reproduce and MEF2C does not; of its three named retained loci, the HOXA cluster reproduces and MYB does not - and GAPDH, the negative control, loses half its share too, The cheap experiment nobody has run: an MLL1 C-TERMINAL ChIP beside the standard N-terminal one in a single human KMT2A-rearranged line under a menin inhibitor - the C-terminus is lost in the fusion, so the difference of the two tracks is the fusion, with no tag and no knock-in, The cheapest unrun test in this beat's queue: GSE260742 deposits an H3K79me2 ChIP under the DOT1L inhibitor SGC0946 in the same murine MLLAF9 cells as its FLAG and MLL1 tracks, which removes the catalysis directly instead of indirectly and would separate 'the mark is stable' from 'residual DOT1L is sufficient' - one download, The chromatin exchange at a menin-inhibited fusion site, measured in one experiment: H2AK119ub and H3K27me3 in, H3K4me3 out, in proportion to how much fusion left - and PCGF1 loss attenuates the in-fill without abolishing it, The deposit names its first replicate "paired" and its later ones rep1/rep2/rep3, so GSM8123403 "H2AK119ub paired" and GSM8123420 "H2AK119ub rep2" are one condition in two replicates - which this project has called "the two processing conventions" since cycle 88. GSE260742 holds 17 genuine same-condition replicate groups, 13 of them histone marks, refuting the claim repeated since cycle 100 that it has none and never will, The eviction quartiles are defined in the 'MLLAF9 Control' FLAG culture and the H3K79me2 they stratify is measured in the 'NTvKO Control' and 'NTvKO PCGF1 KO' cultures - zero shared libraries - so the commonest way a stratified analysis fools itself is structurally unavailable here, The experiment this beat could not do: an epitope-tagged KMT2A::AFF1 ChIP with a Drosophila spike-in, in a human infant-derived B-lineage line, at three replicates and two menin-inhibitor exposures - the design that would turn a within-sample ranking into an absolute occupancy measurement, The first replicated share ratio this corpus has ever had: two title-declared replicates of ONE murine culture span 0.2623 on the same quantity - 4.5x the 0.0584 between-culture spread this corpus uses as its indifference threshold - and they disagree in SIGN about whether the PCGF1 knockout blunts the DOT1L-inhibitor response, The first same-condition H3K79me2 noise floor measured anywhere in this thread: 11.17% at D1 and 26.44% at the TOP 0.1% stratum, against 45.72% and 62.63% for H2AK119ub in the same arm, the same condition and the same pairing shape - 4.1x tighter. A mark floor transferred from H2AK119ub does not describe H3K79me2., The four eviction quartiles are not equivalent stretches of genome: all three GSE260742 input tracks give a monotone increasing share across Q1 to Q4 at Spearman -1.000, 1.15 / 1.17 / 1.13-fold - small, real, in the same direction as the H3K79me2 gradient, and it cancels exactly in a within-genotype drug/vehicle ratio, The GSE260742 H2AK119ub pair that shares a processing state - rep2 against rep3, both bare `.tdf` - is not an unconfounded replicate pair: rep3 was submitted 2024-10-01 and rep2 2024-03-03, through a different file-naming pipeline. No pairing in this deposit isolates replicate variance alone., The H3K27me3 and H3K4me3 NTvKO arms - twelve files nobody had ever binned, listed as second priority - carry the largest effect in this cycle (H3K27me3 2.0007 at the most-evicted quartile, collapsing to 1.0134 in the PCGF1 knockout) and the free internal control that rules out a library artefact (H3K4me3 runs the opposite way, Spearman -1.000), The H3K79me2 eviction gradient against a DMSO-decile-matched null drawn from outside the fusion's sites at the same quartile sizes: the null is flat at 1.030-1.057, none of 20 draws reached the observed span of 0.6005, and the residual retains Spearman -1.000 - but the restricted-population trap is real and the baseline IS graded 2.2-fold, The H3K79me2 eviction gradient is not a ratio of sums dominated by a few bins: the MEDIAN per-bin log2 share ratio is itself monotone at Spearman -1.000, the fraction of bins individually below 1 falls 89.3% to 24.7%, the bootstrap span interval is [-0.651, -0.545], and no single bin moves the span by more than 0.0057, The menin inhibitor's effect on H3K79me2 is a REDISTRIBUTION within the fusion's own site set, not a loss from it: the share falls 41.4% at the quartile the fusion is most evicted from and RISES 18.7% at the quartile it is least evicted from, in murine MLL-AF9, The mid-occupancy floor was computed by three consecutive beats, stored in two committed results files for every contrast, and read as data by none of them - because it was introduced as a normaliser, so no criterion was ever written about it and no verdict ever mentioned it, The mouse fusion fraction is 0.73 and the human proxy fusion fraction is 0.21-0.24 - a three-fold gap in the direction a retroviral over-expression model predicts, so the one place the masking factor can be calibrated against a tag is the one place its value does not transfer, The only deposited H3K79me2 kinetic series for a menin inhibitor is non-monotone - a minimum at 16 h and a recovery at 24 h that survives common support and two rank statistics - and its 24 h point shows MORE redistribution than the 48 h main-arm sample, so the 48 h/72 h asymmetry in cycle 82's F stands and F keeps the words lower bound, The premise that GSE260742 'carries a ChIP-Rx spike-in' does not survive reading the deposit: zero of 158 sample records mention a spike-in, the only ChIP-Rx experiment in the paper is an H2AK119ub panel that is not identifiable among the deposited samples, and 152 of 158 samples ship only an unnormalised igvtools .tdf, The residual fraction this graph says is absent from the entire literature, measured: FLAG-MLLAF9 enrichment at its own top 1,228 sites falls from 15.9x the genome median to 3.0x under VTP50469 - about 18% residual - and 12.8% of those sites stay in the top 0.1%, The same-condition H2AK119ub noise floor in GSE260742 spans twentyfold across the deposit's three experimental arms - D1 |R-1| of 1.89% in the PCGF1-KO clone, 10.49% in the non-targeting control and 37.04% in the MLLAF9 Control arm - at one mark, one lab, one pairing shape and one external stratifier. A single same-condition floor for this deposit does not exist., The shared-epitope masking calibration, run against a FLAG tag and then refuted by its own control: the MLL1 antibody reports 2.23-fold more retained signal than the tag at the fusion's own sites, but MLL1-dominated non-fusion sites fall HARDER than the fusion does (0.1069 against 0.1793), so no mixture of fusion and wild-type MLL1 can produce the observed 0.3995, The universe-overlap gate this thread inherited from cycle 107 divides by a track and multiplies by the stratifier, so it also measures whether both libraries are as deep as the stratifier - a property of the stratifier, not of the pair. It aborted 13 of 16 comparisons here, and cycle 107's own pair passed it by 0.25 percentage points while losing more bins to the stratifier than any pair it refused., This beat pre-registered 'the observed span exceeds the matched-null span by >= 5x' and never said WHICH summary of a 20-draw null: against the maximum it is 3.71x and the criterion fails, against the median it is 30.0x and it passes. The conservative reading was scored and the defect is recorded rather than repaired., This cycle's word 'silenced' means two repressive marks up and one active mark down at 2 kb resolution - GSE260742 deposits no RNA-seq, no nascent transcription and no reporter for either NTvKO genotype, so whether the vacated sites stop being transcribed is unmeasured in the experiment that established they are marked for silencing, Two deposit defects in one beat, both invisible to the check in use: a genome-build verdict read from a file's declared extents names its CONTAINER, and the furthest coordinate carrying signal names its DATA - and a clause that cannot return the other answer has been reported as a passing check in four beats, Two drugs, two spatial mechanisms on one mark: catalytic DOT1L inhibition de-concentrates H3K79me2 out of its peaks and into mid-occupancy chromatin, while menin-interface inhibition lowers the mark's share at the peaks AND at mid-occupancy, so its effect is relocation rather than a smaller version of the same change, Two processing batches inside one GEO series: the FLAG and KDM2B tracks put 1.7-1.9% of their coverage in ENCODE blacklist regions and the BCOR, RING1B and input tracks put 14-46%, with a single 2 kb bin at chr2:98,666,000 carrying 18.1% of the BCOR SGC0946 track on its own, Verified against the live records rather than inherited: HUDEP-2 and mESC each carry a DMSO and an SGC0946 H3K79me2 sample and no VTP-50469 sample, so K562 remains the only fusion-free line in GSE260742 able to score a menin-inhibitor effect - and cycle 82's request for a second and third fusion-free line cannot be met from this series, What fills the space: RING1B and BCOR arrive at the fusion's sites under BOTH drugs, but the DOT1L inhibitor puts them everywhere on the fusion's territory while the menin inhibitor puts them only in the quartile where the fusion is most completely evicted - and at Meis1 RING1B rises 16-fold, When a deposit has no recoverable spike-in, two comparisons still work and one does not: a within-sample rank and a within-sample share both cancel the unknown scale factor, a fold change does not - and the share is the one that also has no ceiling, With H3K79me2 added, the eviction-depth panel over one set of 1,228 bins under one drug is H3K27me3 +1.000, H2AK119ub +1.000, H3K4me3 -1.000 and H3K79me2 -1.000 - a clean repressive-up / active-down split that no shared library, blacklist or regression artefact can produce, Within one arm, swapping the processing-marker confound for a submission-batch confound takes the same-condition H2AK119ub floor from 37.04% to 16.84% at D1 (tighter, 0.45x) and from 37.37% to 61.89% at the TOP 0.1% stratum (worse, 1.66x). The brief's question - tighter, wider, or unchanged - has no single answer, and it is worse exactly where this thread scores its claims.

    used by A filter-free promoter ranking with no peak caller and no target list recovers 40 of the top 50 published oncoprotein-target genes in the drug-free infant sample, and 0 of 50 in the drug-exposed one, An occupancy readout returned background in every channel of the only drug-exposed patient sample it has been tried in - so a negative from such an assay cannot currently be told apart from an assay failure, ENL redistributes rather than persists: it is the only channel that holds more of its signal at the myeloid-program peaks than at the B-lineage ones, by 2.06x in my instrument and 1.26x in the authors' own - and in absolute terms it falls further than menin does, In a patient, the menin-fusion association is demonstrable before the drug and unmeasurable after it - and the asymmetry is what this pair establishes, not a rate of menin loss, In drug-naive primary infant KMT2A::MLLT1 B-ALL, menin is as enriched as the fusion N-terminus at the top fusion promoters (2.73x vs 3.12x over an accessibility reference) while the wild-type C-terminal reporter sits at background (1.10x), In the revumenib-exposed relapse sample nothing is enriched above a non-specific reference - not menin, not the fusion N-terminus, not ENL - and the sample's own top-ranked promoters are mitochondrial pseudogenes, Menin does not outlast the fusion under revumenib in primary infant material - 0.586 against 0.485 at oncoprotein peaks, a ratio of 1.21 against a pre-registered threshold of 1.5 - so the fusion-independent menin plateau seen after a degron does not reproduce here, Menin, ENL and DOT1L are CUT&Tag and the four KMT2A antibodies are CUT&RUN, run three weeks apart - so every menin-versus-fusion comparison in this pair crosses both assay and batch, Neither infant sample has an IgG control, and neither of their two sequencing batches contains one - so every number from this pair is confounded with chromatin accessibility, Spike-in-normalised menin CUT&RUN with paired N- and C-terminal KMT2A antibodies in an infant KMT2A::AFF1 sample, on and off drug, in the same disease state, The KMT2A N-terminal antibody reports wild-type plus fusion and the C-terminal antibody reports wild-type alone - which makes an N-versus-C difference a fusion-specific readout with no tag and no engineering, The menin that matters in an infant KMT2A-rearranged leukaemia is the menin on the fusion, and the N-minus-C antibody difference can measure it in any patient sample without a tag, The menin, ENL and DOT1L replicates of the drug-exposed relapse sample agree with each other at Spearman 0.11 to 0.25, below the floor this project set in the previous cycle, so no quantitative claim from that arm survives

Test the menin - SETD2 - LEDGF - CtIP chain in a blast, before the next genotoxic combination is designed, EXO1 (Q9UQ84, 846 aa) - the long-range resection nuclease at the bottom of the CTCF cascade, and the point where this graph's two independent 2026 HR papers meet: CtIP starts the resection, EXO1/DNA2 finish it, Menin stimulates homology-directed repair through Chk1 and the region required is 1-228: a 2010 paper that is cited in no entry of this graph and in no reference list of the 2026 paper that reports the same conclusion, Menin-SETD2, mapped to the NTD and Palm and tooled with a peptide at menin 231-248: the third partner assigned to the same half of menin, and the writer arm of the HR scaffold, Occupancy-matched three-arm comparison of ziftomenib, revumenib and bleximenib on gamma-H2A.X resolution and HR efficiency in a KMT2A-rearranged B-lineage line, with the peptide competition as the biochemical pre-test, RBBP8 / CtIP - the only unwritten core-complex partner with a DIRECT-interaction record, and the graph already held its mechanism without holding the protein, RPA1 (RPA70) - the large subunit of replication protein A, which carries most of the ssDNA-binding folds and the N-terminal fold that hands the lesion to ATR, The menin acidic shelf, Glu366-Asp370-Val371: the counter-charge that MBM2 binds, resolved in 3U88 after all - and the one patch where the drug pocket, the SvID and the gamma-H2A.X motif all touch, The menin arm and the CTCF arm are not two stories: menin/SETD2/H3K36me3/LEDGF licenses CtIP short-range resection and CTCF/H3K9me/HP1-gamma licenses BRCA1/BARD1-EXO1/DNA2 long-range resection, which are the two consecutive halves of ONE reaction - so a menin inhibitor and an H3K9-axis inhibitor are acting on the same pathway at different steps, The menin-gamma-H2A.X motif, menin Val371-Gln400: necessary, sufficient as a peptide, and the nine residues at its centre have never been seen in any of the 69 menin structures, The menin-inhibitor class splits at Val371: three of four clinical compounds contact the first residue of the gamma-H2A.X motif and bleximenib does not, so DNA-repair effects should separate from KMT2A-displacement effects within the class, The two co-IPs that settle whether menin's SUV39H1 window and its gamma-H2A.X motif are one surface: swap each laboratory's construct into the other's assay, UniProt's menin 214-390 FANCD2 region is not a surface: it spans three spatial lobes and 29.9% of menin's solvent-accessible area, so its twenty-residue overlap with the gamma-H2A.X motif is what chance gives you

    used by A per-sample parameter nobody reads: MACS's fragment-size estimate varies 822-1112 bp across ten ChIPs from one sequencing run, and within the DOT1L arm peak count correlates +0.7 with fragment size and -0.8 with library depth - so the obvious confound is not the operating one, and the non-obvious one is, A tempting second finding that does NOT survive its control: about half of each treated sample's peaks are absent from DMSO, but the two independent VTP-50469 libraries share only 10.5% of their gained sites - against 7.7%, 8.1% and 10.6% for the DOT1L-inhibitor arms - so the gained peaks are threshold noise and there is no evidence of redistribution, CORRECTS A DISPATCH PREMISE: GSE149183's menin-versus-DOT1L-inhibitor head-to-head exists in MOLM13 (KMT2A::MLLT3) ONLY. RS4;11 - the index fusion - is in the series but carries H3K79me2 alone, with no VTP-50469 arm, no MEN1 ChIP and no DOT1L ChIP, and the two arms are on different genome builds, First deposit to put both drug classes on the MEN1 channel in one experiment: VTP-50469 leaves ZERO of the 19 DMSO menin peaks at 15 canonical menin-MLL target loci, while EPZ5676 keeps 14, compound 10 keeps 14 and compound 11 keeps 8 - strength-matched permutation p = 0.0003, and the zero is unchanged at every flank from 0 to 100 kb, In the same deposit, the MENIN inhibitor removes DOT1L from all five DMSO DOT1L peaks at canonical target loci (p = 0.0432) while all three DOT1L inhibitors keep 5/5 - and the VTP DOT1L library still calls ACTB, GAPDH and EEF1A1, which is the internal positive control the MEN1 arm lacks, Novartis 'compound 10' - a DOT1L methyltransferase inhibitor from Perner et al. (Blood 2020), active at 100 nM, whose chemical structure is not given in the GEO deposit and whose target engagement at that dose IS demonstrated in the same series by a 5.6-fold spike-in-normalised H3K79me2 collapse by day 3, Novartis 'compound 11' - a DOT1L methyltransferase inhibitor from Perner et al. (Blood 2020), active at 100 nM, whose chemical structure is not given in the GEO deposit and whose target engagement is not measured anywhere in the series, Resolving cycle 83's threat: the MLL1 channel moves under both drug classes and is therefore not diagnostic, but the MEN1 channel separates them completely - so 'menin displacement' remains a specific readout of menin-interface engagement and the corpus must stop treating the two channels as one, The deposited dm6 spike-in table covers the eighteen H3K79me2 samples and nothing else - the ten MEN1 and DOT1L ChIPs in the same series have no fly chromatin, so every occupancy number from them is a within-sample contrast and no gain-or-loss statement on an absolute scale is available, The menin inhibitor in this head-to-head is at 50 nM and all three DOT1L inhibitors are at 100 nM - the comparison is dose-biased AGAINST the menin inhibitor - and compound 10's target engagement at exactly 100 nM is demonstrated inside the same series by a spike-in-normalised H3K79me2 collapse of 5.6-fold by day 3, The one experiment that would close this beat: MEN1 and DOT1L ChIP in RS4;11 (KMT2A::AFF1) under DMSO, a menin inhibitor and a target-engaging DOT1L inhibitor, with Drosophila spike-in and two replicates per arm - about 24 libraries, and the depositing lab already runs every component of it, The spike-in ruler this thread has been blocked on for eight cycles is deposited as a 2 MB text file, and it includes RS4;11 - the index fusion: under DOT1L inhibition the fly fraction rises 4.9x to 23.4x against matched DMSO, so H3K79me2 collapses GLOBALLY by roughly that factor, and a within-sample share would have shown almost none of it, The whole-peak-set overlap metric cannot tell a MEN1 ChIP from a DOT1L ChIP in the same untreated cells (Jaccard 0.357, inside the 0.310-0.487 range of all 45 sample pairs) - so on the same data it scores cycle 83's threat as SURVIVING while the pre-specified locus set scores it as FALLING, Under all three DOT1L inhibitors, DOT1L's fold-enrichment at canonical target loci is HIGHER than DMSO (PBX3 4.85 to 13.92, SENP6 3.37 to 9.68) - either catalytically dead DOT1L is retained or trapped on chromatin, or the reading is an artefact of a 1.35-fold spread in MACS fragment-size estimates, and this deposit cannot tell which, VTP-50469 - the preclinical menin-KMT2A interface inhibitor that almost every chromatin experiment in this field actually used, and which had no entry of its own in this graph

    Q114-suv39h1-at-the-locus · oncofusion-knowledge-graph 2026
    used by A pre-registered gate of the form 'signal at the top sites / median of random tiles >= 5' returns inf and PASSES on any sparse track, because the median of random 147 bp tiles in a CUT&RUN file is exactly 0.0 - the control was degenerate in three of four tracks and nothing in the output said so, In patient-derived H3K27M glioma, baseline H3K9me3 over the 7,466 bp KMT2A breakpoint cluster core sits at the 7.8th and 28.5th percentile of 59,821 width-matched CTCF-anchor windows (0.56x and 0.90x the random-tile median) - the methyl-poor-BCR pattern this graph found in epithelium and in a blood line, now in a third lineage and for the trimethyl state, Read at last, against a pre-registered class-matched null: in SU-DIPG13 and SU-DIPG36 the SUV39H1 CUT&RUN mean at the KMT2A exon-11 CTCF anchor is 0.0000 and 1.6660 - the first an EXPLICIT zero record, not missing data - and no one of the seven KMT2A intervals in either line exceeds 1.21x the genome-wide random-tile mean. The pre-registered NEGATIVE prior held., The H3K9me3 this graph argues about at the KMT2A exon-11 anchor is not deposited by SUV39H1: in SU-DIPG13 the mark sits at the 57.8th percentile of class-matched CTCF anchors while the writer reads an EXPLICIT ZERO in the same nuclei, and genome-wide the two barely track each other (Spearman 0.148, 0.078), The one experiment that would close the SUV39H1 arm of this graph's H3K9 argument: CST #8729S CUT&RUN in a CD34+ progenitor and in SEM or RS4;11, with an IgG arm and a SUV39H1-degron arm that neither existing deposit has - because after this cycle the enzyme has been measured in exactly two human cell types and neither is a blood cell, The rarest thing in the deposit, measured: across 59,821 CTCF anchors in the SAME nuclei, SUV39H1 occupancy and H3K9me3 correlate at Spearman 0.148 and 0.078 - and a quarter to two-fifths of the enzyme's own strongest sites carry no more of its mark than the median anchor, Two coupled traps in one conversion: pybigtools writes only the chromosomes the input actually touched, so a scaffold in your query set raises KeyError on one track and not another - and when the scaffolds were dropped to fix it, 71 of 59,892 anchors (0.12%) turned out to carry enough of the top signal to HALVE a control's numerator, Two more independent cell types put the KMT2A exon-11 CTCF summit within 12 bp of the coordinate this graph carries: MCF-7 at chr11:118,488,689 (5 bp away) and SK-N-SH at chr11:118,488,682 (12 bp), both score-1000 optimal-IDR peaks - and in the same tracks the anchor ranks only 72.95th of 56,171 MCF-7 anchors, so it is an unambiguous anchor and an ordinary one

    used by Absence: the tissue with the clinical signal is the one tissue nobody has put under a menin inhibitor and measured - one record in the whole literature, and it is a review, ACADM is a mitochondrial matrix beta-oxidation enzyme with an experimentally coded matrix-only localisation, recovered on 8 spectra from a nuclear-extract pulldown whose specific tail is 14.5% mitochondrial — declined, AF9's nuclear residence is chaperone-dependent, the Hsp90 site is the SAME C-terminal region the fusion keeps, and UniProt records no cytoplasmic pool at all, ALKBH5 — the second m6A eraser: a cancer-stem-cell self-renewal role elsewhere, one incidental KMT2A record, and a flat dependency row, Another fusion family did the experiment this beat wants: in FUS::ERG and CBFA2T3::GLIS2 AML, MHC class I and II are absent at diagnosis, EZH2 drives it, and an EZH2 inhibitor restores presentation, ARID1A (BAF250A) - required in the MLL-AF9 screen, present at the Myc enhancers, and flat in every selectivity measure, ARID2 (BAF200) - the PBAF subunit whose loss ACCELERATES MLL-AF9 leukaemia, and which is nonetheless required to maintain it, ATXN7L3 — the shared adaptor that actually sets H2Bub levels, and a KMT2A-selectivity hit nobody in this field has looked at, Audit of the infant presenting-feature evidence: what exists, what does not, what was rejected, what could not be read, B2M (beta-2 microglobulin) - the invariant light chain every MHC class I molecule needs, the classic class I escape route, and a gene this disease's literature has never once named, BICRA (GLTSCR1) - the ncBAF scaffold, zero PubMed records in KMT2A leukaemia, and a lineage-independent dependency in KMT2A-rearranged lines, Bounding an absence the graph already asserts: the H3K79me2 decay half-life, counted, dated and controlled - and why three of the six hits are about the drug's half-life, BRD3 - named in the founding BET paper's own mechanism and in one title since, and not once separated from BRD4 by any experiment in this disease, CBX8 — the one place in this interactome where two good papers flatly disagree, and DepMap takes a side, CD15 (Lewis-x, SSEA-1, 3-fucosyl-N-acetyllactosamine) - a sugar, not a protein: the most-named antigen in this graph that no gene encodes, CD274 (PD-L1) - named in zero entries of this graph until now, a direct MLL1-H3K4me3 target gene in another tissue, and a cell-intrinsic dependency of MLL-AF9 leukaemia-initiating cells, CD65 - a neutral glycolipid epitope (V3FucnLc8Cer), no gene, and the CD number that was split in two because its antibodies did not agree, CD65s (VIM-2, sialylated ceramide dodecasaccharide) - the myeloid antigen that, with CD15, makes NG2 a perfect predictor of KMT2A rearrangement, CDC73 / parafibromin — the PAF1C subunit that was genetically tested, and a second tumour suppressor required by the fusion, CDK4 - the other half of the class name, and it is NOT the gene this disease needs, CEP112 is a 955-residue centrosomal coiled-coil protein on 7 spectra with zero leukaemia literature — its only nuclear annotation is a single 2024 citation, and a long coiled-coil is the classic non-specific AP-MS passenger — declined, CHEK2 (CHK2) - named in every combination mechanism here and measured on its own in none of them, Children with NPM1::ALK lymphoma immunise themselves against their own fusion protein, and the antibody titre predicts relapse - while no autoantibody against any KMT2A fusion has ever been reported. The difference is not the junction; it is that ALK is an ectopic self-antigen and KMT2A and AFF1 are not., CHUK (IKK-alpha) — the only kinase that sits in BOTH NF-kB arms, which makes it the one subunit whose inhibition has an ambiguous sign in this disease, Clec12a is REQUIRED for NUP98::NSD1 AML pathogenesis - a marker turning out to be a dependency, in a different fusion family, and untested in KMT2A-r, CORRECTED: two of eleven CXXC readers HAVE been measured alongside a KMT2A fusion, and the result supports the menin-interface hypothesis, CSNK2A2 - CK2's other catalytic subunit, expressed in every KMT2A-rearranged line and, if anything, slightly favourable to lose, CTR9 — a PAF1C subunit the field assumes is a fusion partner, with no paper that tested it, CXXC4 (IDAX) - TET2's CXXC domain, sitting on a separate gene after an evolutionary inversion, and annotated cytoplasmic only by similarity, CXXC5 (RINF) - the one CXXC reader measurably down-regulated in KMT2A-rearranged AML, which is the only direction-of-change any family member has in this disease, DDX6 - the only protein ever proposed to do for a cell what Tat does for the virus, on the strength of one 2016 paper, DNMT3A - an independent adverse factor in adult KMT2A-rearranged AML and conspicuously absent from paediatric disease, which is the whole finding, DNTT (TdT) - a real gene the graph calls by its enzyme nickname, and TdT-negativity is 100% KMT2A-rearranged in the largest paediatric series, DOT1L's localization record is a mouse kidney paper wearing a human label - and the one image of it in a leukaemia cell is a supporting figure a title search cannot see, DPF2 (BAF45D) - a cBAF-specific reader required in MLL-AF9 cells, with one PubMed record in this disease and no selectivity signal, EBNA1BP2 (EBP2) - the DOT1L spoke with the HIGHEST stoichiometry and the WEAKEST evidence, and the case that shows why abundance is the third dimension, ELP5 (DERP6) - the bridge that joins ELP3 to ELP4, the most essential Elongator subunit in DepMap, and a gene whose cytoplasmic call rests on an overexpression experiment, ELP6 (TMEM103/C3orf75) - an Elongator subunit named after a membrane protein it is not, whose entire localisation record comes from a Drosophila paper its own symbol cannot retrieve, EP400 - the ATPase that swaps H2A.Z in; its complex is required by MLL leukaemia stem cells, and in DepMap it is one of the three genes LEAST required in KMT2A-rearranged lines, Every partner this project imports from the only MLL-fusion AP-MS interactome was pulled from a Strep-HA transgene in Jurkat T-ALL cells — so the host's own lineage factors are in the prey pool, and one of them is LEF1, EWS::FLI1 builds its own enhancers at GGAA microsatellites, and a single inherited base change that lengthens one repeat raises the fusion's binding and the patient's risk. KMT2A fusions occupy pre-existing, invariant CpG islands - which is why this disease has no germline modifier of its target set, and why its mouse models work at all., Experiment — is a KMT2A-septin fusion menin-dependent? The one-plate version, Fever and fatigue: two of the five headline signs cannot be elicited from a baby, Four YEATS antagonists exist, four public transcriptome datasets of YEATS inhibition exist, and not one paper or dataset has ever asked what happens to the AFF2- or AFF3-scaffolded complexes — and the analysis needs no wet work, FTO — highly expressed in MLL-rearranged AML, and the single flattest dependency row in this beat: 0.2% of 1,208 lines, FUT4 - the myeloid alpha-1,3-fucosyltransferase, a hub gene of the KMT2A-rearranged expression module, and the gene HGNC once officially called CD15, FUT9 - the dedicated Lewis-x synthase, structurally solved, and untouched by the KMT2A literature, GATA2 - the least KMT2A-selective gene on this beat, ranking 17,591 of 17,728, and a factor whose leukaemia biology is about stemness and chemoresistance rather than about the fusion, GLUD1 is a hexameric mitochondrial matrix dehydrogenase recovered on 11 spectra with non-zero control signal from a nuclear pulldown — and this corpus has already declined one KMT2A partner whose sole source was a cryo-EM structure of GLUD1 — declined, HCFC2 — menin's other host cell factor, present in the founding paper by gel filtration and never mentioned again, HLA-A - the class I heavy chain a menin inhibitor was actually measured on, and the human orthologue of the MHC class I molecule that protects MLL-AF9 leukaemia stem cells from NK cells, HLA-B - the class I heavy chain the bivalency screen was actually read out on, and the locus that presents the one KMT2A epitope this graph has a structure for, HLA-DR - a two-chain MHC class II heterodimer, so no single gene symbol denotes the surface marker a flow report calls HLA-DR, HLA-DRB1 - the polymorphic beta chain, one of several that can make an HLA-DR dimer, and the reason a chain cannot be inferred from a flow result, HNRNPA2B1 — the panel's strongest KMT2A-selective RNA-layer gene after PTBP1, with ZERO records against MLL or KMT2A, HOXA9 has its own nuclear bodies, and in monocytic AML they move into the eIF4E body - a subnuclear switch measured in patient marrow and never genotyped, Hypothesis: a menin inhibitor must come BEFORE an antigen-directed immunotherapy, not with it or after it - and every published experiment has already assumed this without anyone testing it, Hypothesis: CLEC12A is a cell-intrinsic dependency in KMT2A-rearranged leukaemia, not only a surface marker - and if so, antigen-negative escape is self-defeating, IBTK - the only one of the six DOT1L spokes with a reciprocal test, and its own pulldown in the same study does not find DOT1L, ICOSLG on infant t(4;11) blasts converts T cells into regulatory T cells - the one immune-evasion route measured in this exact disease, in this exact age group, IFNGR1 - the receptor the whole antigen-presentation mechanism runs through, and the one where low-dose interferon-gamma makes MLL-fusion leukaemia worse, IGF2BP2 — the paralogue co-over-expressed with IGF2BP3 in MLL/AF4 B-ALL, and the one with an inhibitor in another leukaemia, IGF2BP3 works in cytoplasmic RNA granules - the only compartment in this beat where a drug is already pointed, and nobody has looked at it in a leukaemia cell, Is the CpG address a contested resource? On current evidence, no - and the beat that went looking says so, JAK1 - recruited and stabilised by AF10 fusions, and the kinase whose downstream STAT1 the class I effect of menin inhibition explicitly does not need, KAT2A / GCN5 - the SAGA catalytic subunit that reaches this disease through its complex rather than through its own symbol, and whose only chemical tool degrades its paralogue too, KDM2A - the CXXC reader that antagonises KMT2A leukaemogenesis, and displaces wild-type MLL rather than the fusion, KHDRBS1 (Sam68) — an RNA-binding protein that holds the MLL-AF4 message DOWN, a class no dropout screen can find, KHDRBS2 (SLM1) — a counted absence: zero leukaemia records over five aliases, in a family that regulates the MLL-AF4 message, KHDRBS3 (SLM2/T-STAR) — the third STAR paralogue, also zero leukaemia records, also flat in DepMap, KMT2A::MLLT11 (MLL-AF1q), t(1;11)(q21;q23) — 28 patients, and not one functional experiment, Kotecha group, Perth: the infant KMT2A-rearranged laboratory this graph had cited once, LEF1 — the Wnt/β-catenin DNA-binding factor of the T-lineage, named as an MLL-AF4-specific interactor in a T-ALL cell line and with essentially no B-lineage or KMT2A literature, MAPK7 (ERK5) - a DOT1L partner on one 1:365 spoke of one atlas pulldown, and a kinase with real leukaemia literature that has never been connected to DOT1L, Mediator's KMT2A signal is in its pan-essential core, CDK8 is expressed and not required at all, and MED13L is rank 9 while its paralogue MED13 is rank 13,569, MEIS1's 'nucleus' is a profile prediction, not a measurement - and a homeodomain-less isoform is cytoplasmic and does the opposite job, Menin binds RPA2 directly, the contact maps to RPA2 aa 43-171 across its low-affinity ssDNA site, and three MEN1 patient missense mutations abolish it - a 2003 finding that this graph had never cited despite menin being its central node, Menin dependence of a non-elongation KMT2A fusion has never been demonstrated — the counted absence, and what the pivotal trial actually enrolled, Menin has no subnuclear compartment, and nobody has looked - the whole published record is two biochemical fractionations, both DNA-damage papers, and no microscopy at all, Menin inhibition reported to induce CLEC12A and sensitise KMT2A-r and NPM1-mutant AML to CLEC12A-directed CAR cells (2026 preprint, not peer reviewed), METTL14 — the other half of the m6A writer, with a real AML mechanism and zero KMT2A-specific records, METTL3 — the m6A writer with a clinical-grade inhibitor, an MLL-rearranged AML mechanism, and a B-lymphoid signal that goes the wrong way, MHC class I is a bivalent gene set, and a menin inhibitor derepresses it - shown in K-562, SCLC and neuroblastoma, and measured on HLA-A in primary AML, but never once in a KMT2A-rearranged cell, NASP - the soluble histone reservoir, and the only gene in this beat with a real selective difference at a pan-essentiality shallow enough to interpret, NF1 - the only tumour-suppressor loss in this disease, and it is a deletion, so a mutation panel cannot see it, NFKB1 (p105/p50) — the only menin-NF-kB subunit with a co-immunoprecipitation, and the arm the MLL leukaemia data points at, NIN (ninein) - a centrosomal scaffold recorded as a DOT1L partner under a UniProt isoform that UniProt itself calls dubious, NLRC5 - the MHC class I transactivator, and the route by which interferon activates class I when KMT2A and KMT2B are both gone, No fusion oncoprotein in any family has a published replication-protein-A measurement: 23 queries across five fusion families and four spelling variants each, every querytranslation read back, zero records - so the PI's analogy dimension for RPA has no comparator at all, and the index fusion's single locus-level result is the entire field, No infant or childhood KMT2A-rearranged cohort has REPORTED IDH status — and at least one has certainly MEASURED it, No orthogonal validation exists for any of the 110 MLL-AF4-specific partners, as far as four declared bounds can see — and the one partner the paper itself followed up, SETD2, is on the opposite list, shared by all seven fusions, No published experiment combines an AKAP95 perturbation with any menin or DOT1L inhibitor - bounded by an enumerated 92-record literature, not by a keyword zero, Non-elongation KMT2A partners considered and not written: what the searches actually returned, partner by partner, PAF1 is annotated as punctate everywhere in the nucleus EXCEPT the nucleolus - and a 2024 proximity map puts it in the nucleolus, Pallor and anaemia in infants: the number this graph quotes does not exist for babies, PARP16 - graded A- in the DOT1L pulldown, the best of the six, and a tail-anchored ER membrane protein that cannot be in the nucleoplasm, PML / TRIM19 (P29590) - the scaffold of PML nuclear bodies, co-purified with all seven MLL fusions, and never once studied as a KMT2A-fusion partner, Q48 enumeration: every antigen, identifier and query this beat ran - including what was searched and rejected, and the three identifier traps found live, RBM15 — m6A adaptor, AMKL fusion partner, and a named hit in the only KMT2A-biased RNA-protein CRISPR screen, RPA-coated single-stranded DNA is the structure that licenses ATR: ATRIP reads it, ATR is brought to the lesion, and CHK1 is activated - which is how this corpus's ATR and CHEK1 entries connect to the clamp that had no entry until now, RPA1 (RPA70) - the large subunit of replication protein A, which carries most of the ssDNA-binding folds and the N-terminal fold that hands the lesion to ATR, RPA1 and RPA2 are curated HGNC aliases of POLR1A and POLR1B, and RPA34 - a UniProt synonym of RPA2 - is an alias of POLR1G, so three of the ssDNA clamp's names point at RNA polymerase I subunits; the hazard is in symbol-based DATABASE lookups, not in PubMed, and the measured contamination says which, RPA2 (RPA32) - the middle subunit of replication protein A, whose disordered N-terminus is the phospho-switch of the replication-stress response and whose 43-171 region binds menin, RPA2 is the only compartment-compatible candidate of the six and the corpus already has a KMT2A resection thread it would fit — but it is an abundant ssDNA-binding subunit on 6 spectra in a benzonase-treated lysate with no RPA1 or RPA3 co-recovered — declined, thread flagged, RPA3 (RPA14) - the 121-residue subunit of replication protein A, which has no annotated domain, no HPA localisation call and no connection to this disease at all, RYBP - the subunit that makes a variant PRC1 complex catalytically active, named by two entries in this graph and never written, SMARCA2 (BRM) - the paralogue nobody measured, and the reason a DepMap rank cannot predict what a BRG1/BRM inhibitor does, SMARCA4 (BRG1) - a tumour suppressor by mutation and a maintenance requirement by knockdown, and in KMT2A-rearranged lines the dependency data say it is not selective at all, SMARCB1 (BAF47/INI1/SNF5) - zero entries, zero mentions and, on the evidence, correctly so: it is lost in primary AML rather than required, SMARCD1 (BAF60A) - rank 59 of 17,728, survives the lineage split, and had never been named in this graph or studied in this disease, SMARCD2 (BAF60B) - named in one KMT2A paper in the whole of PubMed, and the dependency it carries is myeloid identity, not the rearrangement, SMYD3 - a lysine methyltransferase with three claimed histone marks and one robust non-histone substrate, sitting on an HOXA9 feed-forward loop in MLL-AF9 AML and a fatty-acid-oxidation axis in CML stem cells, with zero interventional trials, SREBF1 / SREBP-1 - the weakest of the three MEN1 sterol partners, because it is simultaneously the pathway's readout, SS18 - a SWI/SNF subunit that is itself a fusion partner in another cancer, and a lineage-independent dependency in KMT2A-rearranged lines, SUPT6H (SPT6) - the histone chaperone that rides with RNA polymerase II, which puts it closer to the fusion's proposed mechanism than anything else in this beat, SWI/SNF enumeration for KMT2A-rearranged leukaemia: every subunit searched, every count dated, and what was read and rejected, SYNCRIP (hnRNP Q) — required for MLL leukaemia stem cells in one paper and a tumour suppressor deleted in T-ALL in another, The deferred KMT2A partners: what the counts actually are, what was written, what was rejected, and three numbers the previous enumeration got wrong, The H3K27me3 absence this graph keeps asserting is narrower than stated: the measurement exists, in the genetic arm of the paper the graph cites for the phenocopy, The rule-64 complex-form query that the RPA2 decline flagged as unrun has now been run, and it finds a published damage-state RPA occupancy measurement AT the KMT2A breakpoint cluster region - so two of this corpus's absence entries carry ids that are broader than the claims inside them, The six unwritten DOT1L partners are not six findings - they are nine spokes of ONE GFP-DOT1L pulldown, and the source paper already graded them, This graph recorded 'nobody has looked at AKAP95 in any KMT2A fusion' one cycle before reading the 2026 paper that did - KMT2A returns 0, MLL returns 2, and every cell-line token returns 0 because cell lines live in figures, Three CXXC-pathway activities converge on rDNA - KDM2B represses Pol I, KMT2A and SETD1A bind the whole locus, MLL-AF4 is predominantly nucleolar - and no paper contains two of them, TNF — the only NF-kB-activating ligand with real KMT2A::AFF1 B-ALL evidence, and the evidence says the blasts are RESISTANT to it, TRIM27 - the E3 ligase inside PRC1.1 that USP7 spends its time undoing, and the worst UniProt localisation record this graph has audited, TRRAP — a 3,859-residue DotCom subunit that every cell needs and no KMT2A cell needs more, Two published ways a fusion oncoprotein engages BAF - be a subunit, or recruit it with a disordered domain - and KMT2A has never been tested for either, UBE2A (RAD6A) — the E2 for H2B ubiquitination in one primary account, contradicted by another, and with no KMT2A literature at all, USP8 (UBPY) - the second deubiquitinase KMT2A partner, three patients, same UCH logic, WAC — the adaptor that hands RNF20/RNF40 to RNA polymerase II, and the only member of this axis whose knockdown alone killed MLL-rearranged ALL cells, WEE1 - the one checkpoint target with a KMT2A::AFF1-specific result, and the paper that also found the escape route, What this beat looked at and did not write: rejected candidates, with counts for both halves of every search, What this beat read and did not use: bounded absences, bounded rejections and one bounded unreadable, What this beat searched, what it rejected, and the two papers it could not read - after a fifth route rescued the third, Where LEDGF/p75 actually is: bound to chromatin through mitosis, in the nuclear interior with H3K36me3 - and never once imaged in a KMT2A-rearranged cell, Where RPA actually is: nucleoplasmic and diffuse until there is single-stranded DNA, then punctate prereplication foci at the G1/S border, damage-induced foci with RAD51, and a PML-body pool - and the subunits differ in how well any of this is measured, Which immune-evasion routes are actually documented in KMT2A-rearranged disease, and which are borrowed from AML and assumed - a ranked ledger with the bounded absences that define it, Wild-type AF10 is called nuclear on a construct and found in both fractions in tissue - and that disagreement decides whether CALM-AF10's cytoplasmic life is a gain or an inheritance, WTAP — an oncogenic m6A writer subunit in AML with ZERO records against MLL or KMT2A over six aliases, YAP1 (P46937) - the Hippo pathway's transcriptional co-activator, and a KMT2A fusion partner from a completely different functional class, YTHDC1 — the nuclear m6A reader in the MLL-METTL3-CTCF axis, with an inhibitor, and no dependency signal in KMT2A-rearranged lines, YTHDF2 — the cytoplasmic m6A reader that selectively compromises AML cancer stem cells, discordant across the lineage split here, ZC3H13 — the m6A writer subunit with the most evenly KMT2A-selective dependency signal in the panel, and almost no literature

    · ClinicalTrials.gov 2026
    used by Across 21 stopped trials of menin, DOT1L, BET, CDK9 and LSD1 inhibitors in acute leukaemia, 12 (57%) were stopped for sponsor or enrolment reasons, and the only two risk-benefit stops are one molecule - failure here has mostly been structural, All three withdrawn mechanism-targeted trials admit infants and none of the 52 trials that do not has been withdrawn (exact p = 0.0032, noticed after looking), but the stated reasons are business and administrative and all three are 2025-2026 registrations, Of 62 registered menin- or DOT1L-inhibitor trials, 7 have stopped and none gave a safety reason - four were company or supply decisions - yet the same drugs carry dose-limiting differentiation syndrome and QT prolongation that the registry never mentions, Only 4 of 43 open menin- or DOT1L-inhibitor trials admit infants under one year (9.3%), and only one (TINI-2) is infant-specific, though infants are about a third of the characterised KMT2A-rearranged population, The only two trials stopped on a stated risk-benefit judgement are GSK2879552 (LSD1) studies in AML, while iadademstat, another LSD1 inhibitor, ran a KMT2A-rearranged-enriched expansion with an acceptable safety profile - so the stop looks molecule-specific, and its reason is unread

    used by Adjudicated: CTCF does not do opposite things at KMT2A - it does one thing, and this graph's contradiction is an untested premise about whether a break becomes a rearrangement, CTCF/cohesin occupancy at the KMT2A exon-11 anchor is both the cause of the break and the chaperone of its correct repair - so losing it gives FEWER breaks and MORE rearrangements, Run in coordinates: the protective CTCF site and the patient break-prone window are ONE element, it is cohesin-bound, and the 'functional cut point' is 3.75 kb away - two of the graph's three exon-11s were the same exon and the third was not

Within the K562 map KMT2A's 25-of-50 promiscuity is explained by size (97.1st percentile falling to 90.7th among proteins its own length) and menin is under-reached at the 23.5th, surviving an abundance control.

The `interface-` prefix in its PREFIXES list can never match anything., The bait/prey grade this project uses to triage the interactome systematically discards its strongest evidence, because the strongest methods have no bait, The prey-only interactome is 36.3% written, not 0% - the census, by identity, of all 212 human prey-only partners of the six core proteins, The twelve partners with no entry are three times LESS spoke-expanded than the interactome they came from - 23.1% spoke-only against a 70.6% null, Fisher p = 0.00068, Two thirds of the curated interactome of this project's six core proteins is spoke-expanded - and the pairs this graph chose to write are significantly better than the ones it did not, What a curated interaction row actually claims: spoke expansion, and the ladder from 'was in the same tube' to 'touches'

a DIRECT ATF4 target, and the gene that shows the brief's menin-selectivity claim was PHGDH's and not the pathway's, PSPH (P78330) - the third serine-synthesis enzyme, high in Ewing sarcoma alongside PHGDH and PSAT1, and the one that does NOT fall in leukaemia, Q109 enumeration: the ten panel members that got no entry, the measurement that declined each, the papers read and not used, and four identifier traps measured on this panel, SESN2 / sestrin-2 (P58004) - the ISR's exit into mTORC1: a leucine sensor that falls 1.4 log2 under either inhibitor, and the one panel member with a real structural record, SGK1 / SGK (O00141) - a MENIN-SELECTIVE upregulated kinase, a druggable AGC family member, and the panel's worst platform disagreement, SHMT2 (P34897) - the mitochondrial one-carbon step, and the paralogue that rises while it falls is why its loss may not matter, SOCS2 (O14508) - a MENIN-INHIBITOR-SELECTIVE member of the signature, a cullin-5 E3 substrate receptor, and its likeliest upstream regulator is MEF2C rather than ATF4, STC2 / stanniocalcin-2 (O76061) - the second largest effect in the signature (-4.40 log2), a SECRETED glycoprotein, and its localisation rests on curator inference alone, The 24 genes that respond to BOTH menin inhibitors in RS4;11 are led by the ATF4 stress programme - CHAC1 -5.11, STC2 -4.40, TRIB3 -3.10 - and CHAC1 and TRIB3 are named zero times in this graph, The ATF4/ISR collapse under menin inhibitors reports loss of the KMT2A-fusion transcriptional programme by ANY route, not engagement of the menin interface - and the loss is of ATF4 activity, not ATF4, The experiment that refutes cycle 55's headline was already public: VTP-50469 collapses MEIS1 32-fold in the same line where MI-2-2 left it untouched - and HOXA9 was never actually measured by either dataset, The one experiment that settles this beat: dose-matched menin and DOT1L arms in RS4;11 with H3K4me3 ChIP at PHGDH, plus 13C-serine flux - and it answers the cycle-58 question at the same time, The serine/one-carbon arm is NOT a pure ATF4 output: it is menin-selective where the ISR arm is compound-independent (median margin -0.55 vs -0.02, p=0.011), and it is ABSENT in KMT2A::MLLT3 AML where the ISR arm is present, The serine/one-carbon programme has a SECOND, chromatin-proximal menin input that is not ATF4 - which is why PHGDH is menin-selective where CHAC1 is not, and why the arm is absent in KMT2A::MLLT3, TRIB3 / TRB3 (Q96RU7) - a pseudokinase that is the ISR's own brake, falls 3.1 log2 under either inhibitor, and has a published physical link to the MLL complex in the wrong tissue

    used by All 56 core-complex partners that anyone deliberately fished for already have an entry: the unwritten interactome is 100% by-product, CORRECTED SAME CYCLE: the replication test was UNINFORMATIVE, not negative. Eleven of the twelve proximity panels do not sample the nucleus - they are centrosome, RTK, kinase, ion-channel, CFTR and mitochondrial baits - so KMT2A's 0th percentile in three of them measures panel composition, not promiscuity. In the one transcription-factor panel KMT2A is at the 71.7th and menin is absent, which is DIRECTIONALLY CONSISTENT with the K562 result at n=1, Re-measured against IntAct the interactome is 103/217 (47.5%) covered, up from 41.0%, and the read queue is now ZERO - no partner with two publications or two baits lacks an entry, so the instrument's own ranking criterion has stopped selecting anything. It was also persisting the list of partners that DO have entries while counting and discarding the 105 that do not, which is the exact defect cycle 57 fixed for the other list, The IntAct interactome gap is closed - all 135 'unwritten' interactors are mentioned and 60% carry an explicit decision - while 95 of the 110 partners unique to the INDEX fusion have never been mentioned at all, The interactome tail is orderable after all, just not by evidence: 62 of the 96 unwritten partners are already DISCUSSED somewhere in this corpus and need only promoting to entries, while 34 have never been read at all. Two cycles looked for a priority order in evidence strength and found none, because the ordering that exists is over how much work is left, not over how good the evidence is, Two-thirds of this graph's core-complex interaction evidence comes from experiments where our protein was not the bait, and LEDGF has one bait-supported partner out of thirty-six

The single supporting publication is a PARP-1 heat-shock sumoylation study in which menin is never named, and the row is a HeLa co-IP passenger, Menin is the best-observed of the six core proteins and the only one whose interval separates from the rest - the interface the programme is built on is the one the record actually supports, No BRCA1, BARD1, EXO1, DNA2, HP1-gamma or KDM5A has ever been localised at the KMT2A locus, in any cell type: 21 queries, every querytranslation read back, 0 on-topic records - and the absence splits THREE ways by class, which is what decides what it costs to close, The gap instrument's 'not mentioned anywhere in the corpus' reads only ids, titles and aliases - it was wrong about 9 of 9 this cycle, The interactome instrument is migrated to IntAct REST: 277 partners, 118 written, 42.6% - the denominator grew by 60 and coverage fell 3.5 points, which is the instrument getting honest, The menin arm and the CTCF arm are not two stories: menin/SETD2/H3K36me3/LEDGF licenses CtIP short-range resection and CTCF/H3K9me/HP1-gamma licenses BRCA1/BARD1-EXO1/DNA2 long-range resection, which are the two consecutive halves of ONE reaction - so a menin inhibitor and an H3K9-axis inhibitor are acting on the same pathway at different steps

    used by An occupancy-matched floor built from ~8,600 mid-occupancy promoter windows per track closes a gap Q117 named in its own memo - and it was necessary, because GAPDH and ACTB GAIN share in two of three human lines while Q117 measured them LOSING share in mouse, At the same bins in the same cells, menin's share ratio is 0.20-0.26 and the MLL1 N-terminus antibody's is 0.80-0.91 - so a shared-epitope MLL1-N ChIP under-reports the menin inhibitor's occupancy effect by 3.5 to 4.0-fold, and the number is now measured rather than asserted, Fifty-three 2 kb bins gain MLL1-N-reactive signal under VTP-50469 in RS4;11, and the same 53 coordinates gain 1.77-fold in MOLM13 against a class-matched null of 1.01 with the MOLM13 input flat at 1.01 - so there IS a small, reproducible, input-controlled redistribution, and it carries no CpG-island signature, GSE127507 ran a Drosophila spike-in, measured it, and deliberately did not use it - so the VTP-50469 founding dataset carries no recoverable scale factor either, and the depositors say so in the sample record, HOXA9 is where menin leaves most completely (share ratio 0.14-0.23 over floor) and MLL1-N-reactive material stays most completely (0.74-1.02 over floor), in all three MLL-rearranged lines - so the menin inhibitor decouples menin from the HOXA9 locus without clearing the MLL1 N-terminus from it, MEF2C loses occupancy under VTP-50469 in all three human MLL-rearranged lines (MLL1-N 0.18 / 0.25 / 0.04 over floor), which resolves Q117's one locus-level disagreement with the published account in the paper's favour and localises the disagreement to the murine system, ML-2 (KMT2A::AFDN, a non-elongation partner) is the line where menin eviction is weakest (retains 37.2% of its own top windows against 20.5% and 13.0%) and where the DOT1L track moves most of any track in the beat (retains 31.6%, 13.69 percentile points below a rank-matched null at p = 3e-10) - the opposite pattern to what an AF9/ENL-free fusion would predict, MOLM13 (KMT2A::MLLT3) is the only line in GSE127507 with a matched input in BOTH conditions, and it gives the one differential-input-controlled measurement in the series - MLL1-N occupancy at its own top 0.1% of bins is unchanged (share ratio 0.9438, input 0.9542, input-corrected 0.9891) with ZERO gained bins genome-wide, while menin retains only 13.0% of its own top windows, Q117 predicted an MLL1 ChIP would diverge from FLAG at MYB and agree at MEIS1 - both halves fire in RS4;11 (MYB 1.21 against mouse 0.71, MEIS1 0.25 against 0.23), but the MYB divergence does NOT reproduce in MOLM13, which carries the same fusion as Q117's mouse, so the MYB difference is a partner difference and not an antibody artefact, Tag the endogenous KMT2A::AFF1 allele in RS4;11 and ChIP the tag with and without VTP-50469 alongside MENIN and MLL1-N in the same chromatin - the one experiment that converts every occupancy claim in this literature from a reagent statement into a fusion statement, The deposited GSE127507 processed signal table is an Excel export in which every value at or above 1,000 is a quoted comma-separated string, so a plain numeric parse silently zeroes 34,955 of 386,298 cells - and those cells are the entire top of all eighteen distributions, Under VTP-50469 in RS4;11, the 209 bins that rise to the top of the MENIN distribution are 3.7-fold CpG-island-enriched over a class-matched null at p = 5.2e-07, while the MLL1-N gained set is not enriched at all - so menin's residue is island-biased and an MLL1-N gain is not

    used by At gene-body scale the AFF1-exclusive recurrent class is 6 against an exact institution-stratified null of 0.86 - but the singleton class is 63 against 74, so recurrence carries the signal and exclusivity alone does not, IgG passes this project's occupancy gate at TWICE the rate of the fusion antibody - because the gate is normalised to each library's own promoter mean and IgG has almost none, Run on the reciprocal KMT2A-C antibody instead of the fusion-side KMT2A-N, the same rule gives zero AFF1-exclusive recurrent gene bodies against a null of 0.52 - the gene-scale class is fusion-arm specific, The same occupancy rule passes 0.61% of gene bodies and 10.75% of promoters, so IRX1 at 3 of 27 is 18x its gene-scale expectation where at promoter scale it was below it, Verdict: q147's IRX1 headline survives as a measurement and not as an inference - the pre-registered branch is NEITHER, on U5 and on a FALLS condition that fired

    used by CURATED from committed-but-unread results: murine MLL-AF9 (MLLT3) retains H3K79me2 like human MOLM13 (MLLT3) and unlike RS4;11 (AFF1) - four confirmations fire, two refutations do not, the cross-partner delta is 3.2-3.6x the between-culture spread, and the flatness survives an amplitude stratification in 8 of 8 measurements, CURATED: Q120 called the MLL1-N channel 'inert to three decimals'. At MLL1's OWN top sites in mouse it falls to 0.3012 under a DOT1L inhibitor and 0.3298 under a menin inhibitor - so 'inert' was population-specific, and a drug that does not touch menin moves the MLL1 channel as much as one that does, SALVAGED from a beat killed mid-write: with direct DOT1L inhibition as the positive control that bounds the achievable effect, VTP-50469 achieves only F = 0.09-0.25 of it. SGC0946 strips H3K79me2 to 6.7-14.8% of DMSO; the menin inhibitor leaves 77-91%. And the bin-wise responses do not correlate (rho = -0.026), SALVAGED: in K562, which carries no KMT2A fusion at all, a menin inhibitor moves H3K79me2 as much as it does in fusion-bearing murine MLL-AF9 (V 0.8291 vs 0.7734, F 0.1831 vs 0.2500). Both the confirmation and the refutation fail to fire, and the refutation misses by 0.0057 - this is at-the-edge and must not be read as a clean negative

Reading the entries that have no field shows 10 of 10 carry genuine, specific, cited epigenetic annotation in prose - so the dimension is 56.2% (at least 50.4% on a Wilson bound) and about 20 points of the 'gap' was a formatting artefact
