Poly [ADP-ribose] polymerase 4 is an enzyme that in humans is encoded by the PARP4 gene.This gene encodes poly(ADP-ribosyl)transferase-like 1 protein which 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.
