NCIt synonyms : RCC; X-Ray Repair Cross-Complementing Protein 1; X-Ray Repair Complementing Defective Repair In Chinese Hamster Cells 1; XRCC1; X-Ray Repair Cross Complementing Protein 1; X-Ray Repair Cross Complementing Protein-1;
NCIt definition : DNA repair protein XRCC1 (633 aa, 69 kDa) is encoded by the human XRCC1 gene. This
protein is involved in repair of both DNA strand breakage and improper sister chromatid
exchange.;
NCIt note : XRCC1 is required to interact with polynucleotide kinase (PNK) and poly(ADP-ribose)
polymerase, linking DNA polymerase-beta and DNA ligase III (LIG3) with single-strand
break repair and short-patch base excision repair, respectively.;
