Predicted to enable guanosine-diphosphatase activity; nucleoside-triphosphatase activity; and uridine-diphosphatase activity. Predicted to be involved in nucleoside diphosphate catabolic process. Predicted to act upstream of or within nucleoside diphosphate biosynthetic process and nucleoside monophosphate biosynthetic process. Predicted to be integral component of membrane. Predicted to be active in plasma membrane. Orthologous to human ENTPD8 (ectonucleoside triphosphate diphosphohydrolase 8). [provided by Alliance of Genome Resources, Apr 2022]
