Gene name (HAGRID: 60)

HGNC symbol: PARP1
Aliases: PARP; PPOL; ADPRT
Common name: poly (ADP-ribose) polymerase 1

Potential relevance to the human ageing process

Main reason for selection: Entry selected based on evidence linking the gene product to a pathway or mechanism linked to ageing
Description: The PARP1 enzyme catalyses the transfer of ADP-ribose to a variety of nuclear proteins including members of the high mobility group box and topoisomerase families [984]. It is involved in a variety of processes such as proliferation, differentiation, and recovery from DNA damage [407]. PARP1's levels appear to inversely correlate with mammalian lifespan and PARP1 has been hinted as a determinant of mammalian ageing [68]. PARP1 is a critical mediator of axon growth inhibition. Pharmacological inhibition or genetic loss of PARP1in mouse cells markedly facilitates axon regeneration, thus making PARP1 a potential target to reverse neurological disability [4346]. Nonetheless, more detailed studies are necessary to investigate a role for PARP1 in ageing.
