Summaries for XRCC1 Gene

Entrez Gene Summary for XRCC1 Gene

  • The protein encoded by this gene is involved in the efficient repair of DNA single-strand breaks formed by exposure to ionizing radiation and alkylating agents. This protein interacts with DNA ligase III, polymerase beta and poly (ADP-ribose) polymerase to participate in the base excision repair pathway. It may play a role in DNA processing during meiogenesis and recombination in germ cells. A rare microsatellite polymorphism in this gene is associated with cancer in patients of varying radiosensitivity. [provided by RefSeq, Jul 2008]

CIViC summary for XRCC1 Gene

GeneCards Summary for XRCC1 Gene

XRCC1 (X-Ray Repair Cross Complementing 1) is a Protein Coding gene. Diseases associated with XRCC1 include Spinocerebellar Ataxia, Autosomal Recessive 26 and Gastric Cardia Carcinoma. Among its related pathways are Transcription-Coupled Nucleotide Excision Repair (TC-NER) and Telomere C-strand (Lagging Strand) Synthesis. Gene Ontology (GO) annotations related to this gene include enzyme binding and damaged DNA binding. An important paralog of this gene is ENSG00000268361.

UniProtKB/Swiss-Prot for XRCC1 Gene

  • 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.
