Germline mutations of the human BRCA2 gene confer susceptibility to breast cancer. Although the function of the BRCA2 protein remains to be determined, murine cells homozygous for BRCA2 inactivation display chromosomal aberrations. We have isolated a 2 MDa BRCA2-containing complex and identified a structural DNA binding component, designated as BRCA2-Associated Factor 35 (BRAF35). BRAF35 contains a nonspecific DNA binding HMG domain and a kinesin-like coiled coil domain. Similar to BRCA2, BRAF35 mRNA expression levels in mouse embryos are highest in proliferating tissues with high mitotic index. Strikingly, nuclear staining revealed a close association of BRAF35/BRCA2 complex with condensed chromatin coincident with histone H3 phosphorylation. Importantly, antibody microinjection experiments suggest a role for BRCA2/BRAF35 complex in modulation of cell cycle progression.

Inheritance of mutations in the breast cancer susceptibility gene, BRCA2, predisposes humans to breast and ovarian cancers. Inherited mutations in the BRCA2 gene are also known to cause susceptibility to prostate cancer. BRCA2 protein exists in a large multi-protein complex from which a novel structural DNA binding protein BRCA2-associated factor 35 (BRAF35) has been isolated. We have cloned a novel cDNA encoding an alternatively spliced protein of BRAF35, designated as BRAF25. BRAF25 transcript is present in various human cells. We have precisely mapped the BRAF25 cDNA sequence to the genomic chromosome 19 sequence. Analysis of the predicted sequence of BRAF25 identified a protein of 215 amino acids. BRAF25 contains a truncated high mobility group domain, a kinesin-like coiled-coil domain and multiple Src homology 2 (SH2) motifs. Western blot analysis using antibodies specific for BRAF25 revealed the presence of BRAF25 in human prostate cancer cells.
