X-ray repair complementing defective repair in Chinese hamster cells 5 (double-strand-break rejoining)

On chromosome: 2q35
Known also as: KU80; KUB2; Ku86; NFIV; KARP1; KARP-1; FLJ39089;

NCBI Gene ID: 7520
NCBI Ensembl Id: ENSG00000079246
MIM Id: (from NCBI OMIM database) 194364
Species: Homo sapiens

The protein encoded by this gene is the 80-kilodalton subunit of the Ku heterodimer protein which is also known as ATP-dependant DNA helicase II or DNA repair protein XRCC5. Ku is the DNA-binding component of the DNA-dependent protein kinase, and it functions together with the DNA ligase IV-XRCC4 complex in the repair of DNA double-strand break by non-homologous end joining and the completion of V(D)J recombination events. This gene functionally complements Chinese hamster xrs-6, a mutant defective in DNA double-strand break repair and in ability to undergo V(D)J recombination. A rare microsatellite polymorphism in this gene is associated with cancer in patients of varying radiosensitivity. [provided by RefSeq]
