Poly [ADP-ribose] polymerase 2 is an enzyme that in humans is encoded by the PARP2 gene.This gene encodes poly(ADP-ribosyl)transferase-like 2 protein which contains a catalytic domain and is capable of catalyzing a poly(ADP-ribosyl)ation reaction. This protein has a catalytic domain which is homologous to that of poly (ADP-ribosyl) transferase but lacks an N-terminal DNA binding domain which activates the C-terminal catalytic domain of poly (ADP-ribosyl) transferase.
