Protein Information
Name Runx1
Synonyms Aml1, Cbfa2, Pebp2ab
Function CBF binds to the core site, 5'-PYGPYGGT-3', of a number of enhancers and promoters, including murine leukemia virus, polyomavirus enhancer, T-cell receptor enhancers, LCK, IL-3 and GM-CSF promoters. Essential for the development of normal hematopoiesis. Isoform 4 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. Acts synergistically with ELF4 to transactivate the IL-3 promoter and with ELF2 to transactivate the BLK promoter. Inhibits KAT6B- dependent transcriptional activation (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).
Cellular Location Nucleus.
Tissue Location Isoform 4 is expressed at high levels in thymus, spleen and T-cell lines and at lower levels in myeloid cell lines and nonhematopoietic cells. Isoform 5 is expressed ubiquitously in lumbar vertebrae, brain, kidney, heart, muscle, ovary and osteoblast-like cell line MC3T3-E1
