Abstract:
Poly(ADP-ribose) polymerase(PARP) is a protein-modifying and nucleotide-polymerizing enzyme. As a critical element in DNA repair, PARP can be activated by DNA strand breaks. Excessive activation of PARP, however, can deplete NAD + and ATP, leads to cell death. Cleavage of PARP by activated caspase-3 play an important role in cell apoptosis.
