Alternate Names for XRCC4 Antibody

  • complementing defective, repair in Chinese hamster
  • X-ray repair complementing defective repair in Chinese hamster cells 4
  • X-ray repair cross-complementing protein 4


The protein encoded by this gene functions together with DNA ligase IV and the DNA-dependent protein kinase in the repair of DNA double-strand break by non-homologous end joining and the completion of V(D)J recombination events. The non-homologous end-joining pathway is required both for normal development and for suppression of tumors. This gene functionally complements XR-1 Chinese hamster ovary cell mutant, which is impaired in DNA double-strand breaks produced by ionizing radiation and restriction enzymes. This gene contains 8 exons, and alternative transcription initiation and alternative splicing generates several transcript variants.
