SETD1B (Set1B/KIAA1076) forms an ~450 kDa histone methyltransferase complex containing five non-catalytic subunits: CFP1, Rbbp5, Ash2, Wdr5, and Wdr82. In vitro assays demonstrate the complex produces H3K4me3. A 123-amino acid fragment upstream of the SET domain is required for interaction with CFP1, Ash2, Rbbp5, and Wdr5. Confocal microscopy reveals SETD1B localizes to a largely non-overlapping set of euchromatic nuclear speckles compared to SETD1A, suggesting non-redundant target gene binding. |

SETD1B stability depends on its association with the methyltransferase complex: inducible expression of the carboxyl terminus of SETD1A or SETD1B decreases steady-state levels of both endogenous SETD1A and SETD1B protein without altering levels of the non-catalytic components, indicating feedback regulation through complex-dependent stability. |

Rbm15 and the leukemogenic Rbm15-Mkl1 fusion protein directly interact with SETD1B. This interaction requires the Rbm15 SPOC domain and the SETD1B LSD motif. Overexpression of Rbm15-Mkl1 leads to cytokine-independent cell growth that requires an intact SPOC domain mediating interaction with SETD1B, implicating altered SETD1B complex function in AMKL leukemogenesis. |

In mice, Setd1b is dispensable until after gastrulation (embryos survive to E11.5 but are grossly retarded), whereas Setd1a is required at the epiblast stage. Overexpression of Setd1b cannot rescue the proliferation defects caused by loss of Setd1a in embryonic stem cells, demonstrating non-redundant and developmentally distinct roles for the two Set1 orthologs. |

SETD1B activates iNOS (nos2) expression in tumor-induced myeloid-derived suppressor cells (MDSCs). ChIP revealed enrichment of H3K4me3 (the catalytic product of SETD1B) at the nos2 promoter in MDSCs; inhibition or silencing of SETD1B diminished iNOS expression, demonstrating that SETD1B-mediated H3K4me3 deposition at the nos2 promoter drives iNOS transcription in an IRF8-independent manner. |

Conditional deletion of Setd1b in adult mice using ubiquitous and hematopoietic-specific strategies results in peripheral thrombo- and lymphocytopenia, multilineage dysplasia, myeloid-biased extramedullary hematopoiesis, and lethality. Transplantation experiments and expression profiling show Setd1b is autonomously required in hematopoietic lineages and regulates key lineage specification genes including Cebpa, Gata1, and Klf1. |

SET1B (SETD1B) is recruited to HIF target gene loci by the HIF transcription factor complex in hypoxia. SET1B accumulates on chromatin under hypoxic conditions, and its loss selectively reduces H3K4me3 at HIF target loci, correlating with decreased promoter acetylation and gene expression. Genome-wide mutagenesis screen identified SET1B as required for HIF transcriptional activity. |

Postnatal SETD1B in excitatory neurons controls expression of a set of genes with broad H3K4me3 peaks at their promoters, enriched for neuron-specific genes linked to learning and memory. Conditional deletion of Setd1b in excitatory forebrain neurons leads to severe learning impairment. Comparative ChIP-seq and RNA-seq with Kmt2a and Kmt2b conditional knockouts show SETD1B plays a more pronounced role in regulating neuron-enriched, broad-H3K4me3-marked genes. |

Loss of SETD1B in oocytes (conditional KO) causes redistribution of H3K4me3: losses at active gene promoters associated with downregulated gene expression, and gains at DNA-hypomethylated, transcriptionally inactive, CpG-rich regions (hallmarks of MLL2/KMT2B targets). This reveals two complementary mechanisms of H3K4me3 targeting in oogenesis—SETD1B linked to gene expression and MLL2 to CpG content—and shows SETD1B normally suppresses MLL2-mediated methylation at these sites. |

SETD1B is required for mycolactone-induced cell death. CRISPR/Cas9 inactivation of SETD1B renders cells resistant to lethal doses of mycolactone. Mechanistically, SETD1B is required for mycolactone-selective upregulation of CHAC1 (a GSH-degrading enzyme), and SETD1B loss prevents mycolactone-induced glutathione depletion and apoptotic gene induction. |

SETD1B mutations/deletions in B cell lymphoma confer resistance to the BCL2 inhibitor Venetoclax and an MCL-1 inhibitor. Mechanistically, SETD1B is required for expression of several proapoptotic BCL2 family proteins (including BIM and BIK). KDM5 histone H3K4 demethylase inhibitors restore BIM and BIK expression and synergize with Venetoclax in SETD1B-deficient lymphomas. SETD1B cooperates with KMT2D loss in lymphoma development in vivo. |

SETD1B SET domain disruption (via CRISPR tiling) in MLL-rearranged AML cells causes depletion of AML cells and downregulation of MYC pathway genes. SETD1B SET domain loss results in decreased H3K4me3 breadth at gene loci; exogenous MYC expression or disruption of H3K4 demethylase KDM5C rescues growth defects, establishing SETD1B's catalytic domain as required for broad H3K4me3 and MYC expression. |

In Xenopus, maternal Setd1b is required for organizer gene expression during dorsal axis development. Depletion of Setd1b impairs organizer gene activation, indicating that Setd1b-mediated H3K4 trimethylation is required downstream of the maternal Wnt/β-catenin pathway for proper organizer formation. |

YTHDF2 physically interacts with SETD1B (but not SETD1A or CXXC1) in the cerebellum. Loss of Ythdf2 suppresses Setd1b-mediated H3K4me3 deposition and reduces chromatin accessibility at neuronal developmental gene loci. Setd1b knockdown rescues the neural self-renewal and differentiation defects caused by Ythdf2 deletion, placing SETD1B downstream of YTHDF2 in cerebellar development. |
