GenAge entry for XRCC5 (Homo sapiens)

Entry selected based on evidence directly linking the gene product to ageing in a mammalian model organism

Gene name (HAGRID: 112)

HGNC symbol: XRCC5
Aliases: KU80; KARP-1; Ku86; KUB2
Common name: X-ray repair complementing defective repair in Chinese hamster cells 5 (double-strand-break rejoining)

Potential relevance to the human ageing process

Main reason for selection: Entry selected based on evidence directly linking the gene product to ageing in a mammalian model organism
Description: XRCC5, or Ku80, is a helicase involved in DNA repair and chromatin remodelling [577]. It has been found associated with the telomeres [158] and with WRN [983]. XRCC5-null mice live about 38 weeks and appear to age prematurely [1490]. As such, XRCC5 may play a role in human ageing.
