CBFB is the beta subunit of a heterodimeric core-binding transcription factor belonging to the PEBP2/CBF transcription factor family which master-regulates a host of genes specific to hematopoiesis (e.g., RUNX1) and osteogenesis (e.g., RUNX2). The beta subunit is a non-DNA binding regulatory subunit, it allosterically enhances DNA binding by alpha subunit as the complex binds to the core site of various enhancers and promoters, including murine leukemia virus, polyomavirus enhancer, T-cell receptor enhancers and GM-CSF promoters.Synonyms: CBF beta, CBF-beta, Core-binding factor beta, PEA2-beta, PEBP2-beta, Polyomavirus enhancer-binding protein 2 beta subunit, SL3-3 enhancer factor 1 subunit beta, SL3/AKV core-binding factor beta subunit
