Predicted to enable several functions, including identical protein binding activity; phosphate ion binding activity; and purine-nucleoside phosphorylase activity. Predicted to be involved in several processes, including nucleobase-containing small molecule metabolic process; positive regulation of interleukin-2 production; and purine-containing compound salvage. Predicted to be located in extracellular region and nucleus. Predicted to be active in cytoplasm. Is expressed in alimentary system and intestine. Human ortholog(s) of this gene implicated in purine nucleoside phosphorylase deficiency and purine-pyrimidine metabolic disorder. Orthologous to human PNP (purine nucleoside phosphorylase).
