T29630 (Former ID: TTDI02414)
Runt-related transcription factor 3 (RUNX3)
SL3/AKV core-binding factor alpha C subunit; SL3-3 enhancer factor 1 alpha C subunit; Polyomavirus enhancer-binding protein 2 alpha C subunit; PEBP2A3; PEBP2-alpha C; PEA2-alpha C; Oncogene AML-2; Core-binding factor subunit alpha-3; CBFA3; CBF-alpha-3; Acute myeloid leukemia 2 protein; AML2
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. May be involved in the control of cellular proliferation and/or differentiation. In association with ZFHX3, upregulates CDKN1A promoter activity following TGF-beta stimulation. 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. Forms the heterodimeric complex core-binding factor (CBF) with CBFB.
