Gene Overview
The protein encoded by CFBF can bind the protein encoded by RUNX1 to form "Core Binding Factor", a hetero-dimeric transcription factor, which regulates a number of genes responsible for hematopoiesis and osteogenesis (2). The beta subunit is a non-DNA binding regulatory subunit and it allosterically enhances DNA binding by alpha subunit (Runx1 protein). 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.
