| description | The breast cancer susceptibility gene contains at its C terminus two copies of a conserved domain that was named BRCT for BRCA1 C terminus. This domain of about 95 amino acids is found in a large variety of proteins involved in DNA repair, recombination and cell cycle control [, , ]. The BRCT domain is not limited to the C-terminal of protein sequences and can be found in multiple copies or in a single copy as in RAP1 and TdT. Some data []indicate that the BRCT domain functions as a protein-protein interaction module.The structure of the first of the two C-terminal BRCT domains of the human DNA repair protein XRCC1 has been determined by X-ray crystallography, it comprises a four-stranded parallel β-sheet surrounded by three α-helices, which form an autonomously folded domain []. |
