Background

  • Function

    RUNX1 (Runt-related transcription factor 1) is a pivotal hematopoietic transcription factor that orchestrates lineage specification, stem cell maintenance, and differentiation[1][2]. Mechanistically, RUNX1 regulates multiple signaling pathways, including NF-κB, PI3K/AKT, and TGF-β, modulating immune responses, inflammation, and hematopoietic proliferation[2][3][4]. In early hematopoiesis, isoforms such as RUNX1b and RUNX1-205 exhibit distinct temporal functions, with RUNX1-205 blocking hemogenic endothelial emergence while promoting late-stage hematopoietic differentiation[5][6]. RUNX1 mutations or haploinsufficiency contribute to leukemia, myelodysplastic syndromes, familial platelet disorders, and influence sensitivity to chemotherapeutic agents, demonstrating its disease relevance[1][3][7][8]. Compared with RUNX2 and RUNX3, RUNX1 exhibits unique tissue-specific expression and isoform-dependent regulation, particularly in hematopoietic and renal epithelial cells, underscoring functional distinctions within the RUNX family[1][9][4]. Pharmacologically, small molecule inhibitors targeting RUNX1-CBFβ interaction or TGF-β pathways have been shown to modulate RUNX1 activity, restore hematopoietic defects, and reduce inflammation and fibrosis in experimental models, suggesting translational potential[10][7][4]. RUNX1 also regulates platelet function and aspirin-responsive gene expression, highlighting its relevance in cardiovascular disease and cancer prevention[11]. Collectively, RUNX1 serves as a central transcriptional hub connecting developmental, inflammatory, and pathological processes, making it a critical focus for both mechanistic studies and therapeutic exploration.

    Phosphorylated in its C-terminus upon IL-6 treatment. Phosphorylation enhances interaction with KAT6A;Methylated;Phosphorylated in Ser-249 Thr-273 and Ser-276 by HIPK2 when associated with CBFB and DNA. This phosphorylation promotes subsequent EP300 phosphorylation

  • Subunit

    Heterodimer with CBFB. RUNX1 binds DNA as a monomer and through the Runt domain. DNA-binding is increased by heterodimerization. Isoform AML-1L can neither bind DNA nor heterodimerize. Interacts with TLE1 and ALYREF/THOC4 (PubMed:9119228, PubMed:9751710). Interacts with ELF1, ELF2 and SPI1 (PubMed:10207087). Interacts via its Runt domain with the ELF4 N-terminal region (PubMed:10207087). Interaction with ELF2 isoform 2 (NERF-1a) may act to repress RUNX1-mediated transactivation (PubMed:14970218). Interacts with KAT6A and KAT6B (PubMed:11742995, PubMed:11965546). Interacts with SUV39H1, leading to abrogation of transactivating and DNA-binding properties of RUNX1 (PubMed:12917624, PubMed:16652147). Interacts with YAP1 (PubMed:18280240). Interacts with HIPK2 (By similarity). Interaction with CDK6 prevents myeloid differentiation, reducing its transcription transactivation activity. Found in a complex with PRMT5, RUNX1 and CBFB. Interacts with FOXP3 (PubMed:17377532). Interacts with TBX21 (By similarity). Interacts with DPF2 (PubMed:28533407)
