Enables nucleoside-diphosphatase activity and nucleoside-triphosphatase activity. Acts upstream of or within nucleoside diphosphate catabolic process and nucleoside triphosphate catabolic process. Located in plasma membrane. Is expressed in several structures, including alimentary system; central nervous system; respiratory system; sensory organ; and skeleton. Orthologous to human ENTPD3 (ectonucleoside triphosphate diphosphohydrolase 3). [provided by Alliance of Genome Resources, Apr 2022]
