AML3 (human)

AML3 Transcription factor involved in osteoblastic differentiation and skeletal morphogenesis. Essential for the maturation of osteoblasts and both intramembranous and endochondral ossification. 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, osteocalcin, osteopontin, bone sialoprotein, alpha 1(I) collagen, LCK, IL-3 and GM-CSF promoters. In osteoblasts, supports transcription activation: synergizes with SPEN/MINT to enhance FGFR2-mediated activation of the osteocalcin FGF-responsive element (OCFRE). Inhibits KAT6B-dependent transcriptional activation. Interaction with SATB2 results in enhanced DNA binding and transactivation by these transcription factors. Heterodimer of an alpha and a beta subunit. Interacts with HIVEP3 and HIPK3. The alpha subunit binds DNA as a monomer and through the Runt domain. DNA-binding is increased by heterodimerization. Interacts with XRCC6 (Ku70) and XRCC5 (Ku80). Interacts with KAT6A and KAT6B. Binds to cyclin B1 CCNB1. Interacts with DDX5. Specifically expressed in osteoblasts. 3 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
