摘要
Poly(ADP-ribose) polymerases (PARPs) catalyze the post-translational modification of proteins with poly(ADP-ribose). Two PARP isoforms, PARP-1 and PARP-2, display catalytic activity by contact with DNA-strand breaks and are involved in DNA base-excision repair and other repair pathways. A body of correlative data suggests a link between DNA damage-induced poly(ADP-ribosyl)ation and mammalian longevity. Recent research on PARPs and poly(ADP-ribose) yielded several candidate mechanisms through which poly(ADP-ribosyl) ation might act as a factor that limits the rate of ageing.
