Predicted to enable kinase binding activity; pentosyltransferase activity; and protein serine/threonine kinase activator activity. Predicted to be involved in several processes, including IRE1-mediated unfolded protein response; positive regulation of protein serine/threonine kinase activity; and protein ADP-ribosylation. Predicted to act upstream of or within cellular response to leukemia inhibitory factor. Predicted to be located in endoplasmic reticulum. Predicted to be active in endoplasmic reticulum tubular network and nuclear envelope. Orthologous to human PARP16 (poly(ADP-ribose) polymerase family member 16).
