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]

GeneCards Summary for XRCC1 Gene

XRCC1 (X-Ray Repair Complementing Defective Repair In Chinese Hamster Cells 1) is a Protein Coding gene. Diseases associated with XRCC1 include Gastric Cardia Carcinoma and Fibrosclerosis Of Breast. Among its related pathways are FOXM1 transcription factor network and Transcription-Coupled Nucleotide Excision Repair (TC-NER). GO annotations related to this gene include enzyme binding and damaged DNA binding. An important paralog of this gene is ENSG00000268361.
