XRCC1 (X-ray cross complementing factor-1) is involved in DNA base excision repair. XRCC1 is a 70 kDa protein that has been shown to be physically associated with other DNA repair enzymes, including poly (ADP-ribose) polymerase (PARP), DNA Ligase III and DNA polymerase beta. XRCC1 contains a BRCT domain (for BRCA1 carboxyl terminus) which was originally found in the tumor suppressor protein BRCA1. Recently, the BRCT domain has been shown to mediate the protein-protein interaction of XRCC1 and DNA ligase III-alpha.
