Poly [ADP-ribose] polymerase 3 is an enzyme that in humans is encoded by the PARP3 gene.The protein encoded by this gene belongs to the PARP family. These enzymes modify nuclear proteins by poly-ADP-ribosylation which is required for DNA repair regulation of apoptosis and maintenance of genomic stability. This gene encodes the poly(ADP-ribosyl)transferase 3 which is preferentially localized to the daughter centriole throughout the cell cycle.
