XRCC1 Involved in DNA single-strand break repair by mediating the assembly of DNA break repair protein complexes. Probably during DNA repair, negatively regulates ADP-ribose levels by modulating ADP-ribosyltransferase PARP1 activity. Expressed in fibroblasts, retinal pigmented epithelial cells and lymphoblastoid cells (at protein level). Note: This description may include information from UniProtKB.
