The BRCA2-Associated Factor 35 (BRAF35) protein forms a 20 kDa complex with BRCA2, which associates with condensed chromatin during histone H3 phosphorylation.BRAF35 expression levels are highest in proliferating tissues and parallel BRCA2 expression patterns. The structure of BRAF35 includes a kinesinlike coiled coil domain and a nonspecific DNA binding HMG domain. The chromatin localization of BRAF35 and antibody microinjection studies indicate a role for the BRAF35/BRCA2 complex in cell cycle regulation.
