Predicted to enable NAD+ ADP-ribosyltransferase activity; enzyme binding activity; and protein ADP-ribosylase activity. Predicted to be involved in several processes, including inflammatory response; protein mono-ADP-ribosylation; and regulation of telomerase activity. Predicted to act upstream of or within protein ADP-ribosylation. Predicted to be located in cytosol and spindle microtubule. Orthologous to human PARP4 (poly(ADP-ribose) polymerase family member 4).
