Predicted to enable metal ion binding activity; nucleoside-triphosphate diphosphatase activity; and phosphodiesterase I activity. Predicted to be involved in several processes, including negative regulation of mast cell activation involved in immune response; negative regulation of mast cell proliferation; and nucleoside phosphate metabolic process. Predicted to be located in external side of plasma membrane and perinuclear region of cytoplasm. Orthologous to human ENPP3 (ectonucleotide pyrophosphatase/phosphodiesterase 3).
