title: CBF--a biophysical perspective.
abstract: Core binding factor (CBF) is a heterodimeric transcription factor consisting of a DNA-binding subunit (Runx, also referred to as CBFA, AML 1, PEBP2alpha) and a non-DNA-binding subunit (CBFB). Biophysical characterization of the two proteins (and their interactions is providing a detailed understanding of this important transcription factor at the molecular level. Measurements of the relevant binding constants are helping to elucidate the mechanism of leukemogenesis associated with altered forms of these proteins. Determination of the 3D structures of CBFB and the DNA- and CBFB-binding domain of Runx, referred to as the Runt domain, are providing a structural basis for the functioning of the two proteins of CBF.
