WebPoly (ADP-ribose) polymerase (PARP) is a nuclear enzyme that functions as a sensor for single- and double-stranded DNA breaks ( Masutani et al., 1995 ). PARP catalyzes the cleavage of NAD+ into nicotinamide and ADP-ribose and uses the latter to synthesize branched nucleic acid-like polymers ( de Murcia et al., 1994 ).
