CBF binds to various enhancers and promoters including murine leukemia virus and polyomavirus enhancer. Disease Mutations in CBF β are implicated in breast cancer. Rearrangements of CBF α and β genes are implicated in acute myeloid leukemia. Structural highlights CBF α contains a DNA-binding runt domain (residues 50-177).
