Summary

CBFB (core-binding factor subunit beta, HGNC:1539) is a protein-coding gene on chromosome 16q22.1, encoding Core-binding factor subunit beta (Q13951). Forms the heterodimeric complex core-binding factor (CBF) with RUNX family proteins (RUNX1, RUNX2, and RUNX3). It is a selective cancer dependency (DepMap: 21.6% of cell lines).

The protein encoded by this gene 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. Alternative splicing generates two mRNA variants, each encoding a distinct carboxyl terminus. In some cases, a pericentric inversion of chromosome 16 [inv(16)(p13q22)] produces a chimeric transcript consisting of the N terminus of core-binding factor beta in a fusion with the C-terminal portion of the smooth muscle myosin heavy chain 11. This chromosomal rearrangement is associated with acute myeloid leukemia of the M4Eo subtype. Two transcript variants encoding different isoforms have been found for this gene.

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. (Microbial infection) Following infection, hijacked by the HIV-1 Vif protein, leading to the formation a cullin-5-RING E3 ubiquitin-protein ligase complex (ECS complex) that catalyzes ubiquitination and degradation of APOBEC3F and APOBEC3G. The complex can also ubiquitinate APOBEC3H to some extent. Association with HIV-1 Vif protein also inhibits the transcription coactivator activity of CBFB/CBF-beta.

Subunit / interactions. Heterodimer with RUNX1, RUNX2 and RUNX3. Interacts with COPRS. Found in a complex with PRMT5 and RUNX1. (Microbial infection) Interacts with HIV-1 Vif; forming an active cullin-5-RING E3 ubiquitin-protein ligase complex (ECS complex).

Subcellular location. Nucleus.

Disease relevance. 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. Cleidocranial dysplasia 2 (CLCD2) [MIM:620099] A form of cleidocranial dysplasia, a rare skeletal disorder with significant clinical variability, even within families. Patients typically present with delayed closure of cranial sutures and fontanels with multiple Wormian bones, retarded ossification of the skull, shortening of the distal phalanges, dental anomalies including supernumerary teeth and eruption failure, clavicular hypoplasia or aplasia, wide pubic symphysis, vertebral anomalies, and short stature. Craniofacial features are subtle and characterized by prominent parietal and frontal bones, widely spaced eyes, depressed nasal bridge and small maxilla. Some CLCD2 patients present mild to moderate developmental delay. CLCD2 inheritance is autosomal dominant. The disease is caused by variants affecting the gene represented in this entry.

Similarity. Belongs to the CBF-beta family.
