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.

A large portion of human kinesin superfamily protein member 4 (KIF4) is associated with the nuclear matrix during the interphase, while a small portion is found in the cytoplasm. During mitosis, it is associated with chromosomes throughout the entire process. In the present study, we identified a protein that interacts with KIF4 using a yeast two-hybrid system, co-immunoprecipitation and co-fractionation. This protein is BRCA2-associated factor 35 (BRAF35) containing a non-specific DNA binding high-mobility-group domain and a kinesin-like coiled-coil domain. It appeared that the interaction between the two proteins occurs through their respective alpha-helical coiled-coil domains. The co-fractionation experiment revealed that KIF4 and BRAF35 were present in a complex of approx. 540 kDa. The composition and biological significance of this complex should be studied further.
