FunctionPEBB_MOUSE 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. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe core binding factor beta subunit (CBF beta) is the non-DNA binding subunit of the core-binding factors, transcription factors essential for multiple developmental processes including hematopoiesis and bone development. Chromosomal translocations involving the human CBFB gene are associated with a large percentage of human leukemias. The N-terminal 141 amino acids of CBF beta contains the heterodimerization domain for the DNA-binding CBF alpha subunits, and is sufficient for CBF beta function in vivo. Here we present the high-resolution solution structure of the CBF beta heterodimerization domain. It is a novel alpha/beta structure consisting of two three-stranded beta-sheets packed on one another in a sandwich arrangement, with four peripheral alpha-helices. The CBF alpha binding site on CBF beta has been mapped by chemical shift perturbation analysis.
