Previous GeneCards Identifiers for CBFB Gene
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.

GeneCards Summary for CBFB Gene
CBFB (Core-Binding Factor, Beta Subunit) is a Protein Coding gene. Diseases associated with CBFB include 'acute myeloid leukemia with abnormal bone marrow eosinophils inv(16)(p13q22) or t(16;16)(p13;q22)' and lymphoplasmacytic lymphoma. Among its related pathways are ATF-2 transcription factor network and Regulation of nuclear SMAD2/3 signaling. GO annotations related to this gene include sequence-specific DNA binding transcription factor activity and transcription coactivator activity.
UniProtKB/Swiss-Prot for CBFB Gene
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, LCK, IL3 and GM-CSF promoters. CBFB enhances DNA binding by RUNX1
