Predicted to enable NAD+-protein poly-ADP-ribosyltransferase activity. Acts upstream of or within cellular response to xenobiotic stimulus. Predicted to be active in nucleus. Is expressed in several structures, including digestive system; forebrain neural keel; nervous system; neural plate; and neural tube. Orthologous to human TIPARP (TCDD inducible poly(ADP-ribose) polymerase).
