Cleaved poly(ADP-ribose) polymerase-1
Background
PARP1 (Poly(ADP-ribose) polymerase 1) belongs to PARP-superfamily DNA-repair enzyme family responsible for DNA-damage sensing and poly-ADP-ribosylation. Cleaved PARP1 is a hallmark apoptotic fragment. Full-length PARP1 senses DNA strand breaks and catalyzes PAR-modification to recruit repair machineries. During apoptosis, activated caspase-3/7 cleaves PARP1 at Asp214 to generate 89 kDa C-terminal fragment and 24 kDa N-terminal fragment, abolishing PARP1-mediated DNA-repair capacity. Cleaved-PARP1 antibody exclusively detects apoptotic cleavage product instead of total full-length PARP1.
