Mouse Anti-RUNX1 Monoclonal Antibody (3D7) (CBMAB-0061-LY)

RUNX1

The protein encoded by this gene represents the alpha subunit of CBF and is thought to be involved in the development of normal hematopoiesis. Runx1 protein is seen in the mesodermal masses and endoderm of the prospective yolk sac blood islands at the neural plate stage, in the mesoderm of the distal allantois and chorion (precursors of the placenta) at headfold stages7, and in endothelial cells in the distal allantois, dorsal aorta, and vitelline and umbilical arteries starting the 4–6 somite pair stage. Runx1 is required in mesoderm, endoderm, mesenchyme and/or endothelial cells for intra-arterial cluster and HSC formation.

AML1; AMLCR1; CBFA2; PEBP2A2

Forms the heterodimeric complex core-binding factor (CBF) with CBFB. RUNX members modulate the transcription of their target genes through recognizing the core consensus binding sequence 5'-TGTGGT-3', or very rarely, 5'-TGCGGT-3', within their regulatory regions via their runt domain, while CBFB is a non-DNA-binding regulatory subunit that allosterically enhances the sequence-specific DNA-binding capacity of RUNX. The heterodimers bind to the core site of a number of enhancers and promoters, including murine leukemia virus, polyomavirus enhancer, T-cell receptor enhancers, LCK, IL3 and GM-CSF promoters (Probable). Essential for the development of normal hematopoiesis (PubMed:17431401).
Acts synergistically with ELF4 to transactivate the IL-3 promoter and with ELF2 to transactivate the BLK promoter (PubMed:10207087, PubMed:14970218).
Inhibits KAT6B-dependent transcriptional activation (By similarity).
Involved in lineage commitment of immature T cell precursors. CBF complexes repress ZBTB7B transcription factor during cytotoxic (CD8+) T cell development. They bind to RUNX-binding sequence within the ZBTB7B locus acting as transcriptional silencer and allowing for cytotoxic T cell differentiation. CBF complexes binding to the transcriptional silencer is essential for recruitment of nuclear protein complexes that catalyze epigenetic modifications to establish epigenetic ZBTB7B silencing (By similarity).
Controls the anergy and suppressive function of regulatory T-cells (Treg) by associating with FOXP3. Activates the expression of IL2 and IFNG and down-regulates the expression of TNFRSF18, IL2RA and CTLA4, in conventional T-cells (PubMed:17377532).
Positively regulates the expression of RORC in T-helper 17 cells (By similarity).
Isoform AML-1G shows higher binding activities for target genes and binds TCR-beta-E2 and RAG-1 target site with threefold higher affinity than other isoforms. It is less effective in the context of neutrophil terminal differentiation.
Isoform AML-1L interferes with the transactivation activity of RUNX1.

Nucleus

Familial platelet disorder with associated myeloid malignancy (FPDMM):
Autosomal dominant disease characterized by qualitative and quantitative platelet defects, and propensity to develop acute myelogenous leukemia.

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.
