Predicted to enable histone binding activity; pentosyltransferase activity; and zinc ion binding activity. Predicted to be involved in several processes, including negative regulation of maintenance of mitotic sister chromatid cohesion, telomeric; protein ADP-ribosylation; and regulation of nucleobase-containing compound metabolic process. Predicted to act upstream of or within peptidyl-serine phosphorylation and peptidyl-threonine phosphorylation. Located in cytosol. Is expressed in central nervous system; dorsal root ganglion; and neural retina. Orthologous to human TNKS (tankyrase). [provided by Alliance of Genome Resources, Apr 2022]
