| UniProt functional annotation for Q13951 | |||
| UniProt code: Q13951. |
| Organism: | Homo sapiens (Human). | |
| Taxonomy: | Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo. | |
| Function: | Forms the heterodimeric complex core-binding factor (CBF) with RUNX family proteins (RUNX1, RUNX2, and RUNX3). 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. 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. {ECO:0000250|UniProtKB:Q08024}. | |
| Subunit: | Heterodimer with RUNX1, RUNX2 and RUNX3. Interacts with COPRS. Found in a complex with PRMT5 and RUNX1. {ECO:0000250|UniProtKB:Q08024}. | |
| Subcellular location: | Nucleus {ECO:0000305}. | |
| Disease: | Note=A chromosomal aberration involving CBFB is associated with acute myeloid leukemia of M4EO subtype. Pericentric inversion inv(16)(p13;q22). The inversion produces a fusion protein that consists of the 165 N-terminal residues of CBF-beta (PEPB2) with the tail region of MYH11. {ECO:0000269|PubMed:8351518}. | |
| Similarity: | Belongs to the CBF-beta family. {ECO:0000305}. | |
