Predicted to enable NAD+ ADP-ribosyltransferase activity. Predicted to be involved in several processes, including positive regulation of canonical Wnt signaling pathway; positive regulation of telomere capping; and protein localization to chromosome, telomeric region. Predicted to be active in cytoplasm and nucleus. Orthologous to human ANKRD39 (ankyrin repeat domain 39). [provided by Alliance of Genome Resources, Apr 2022]
