Predicted to enable several functions, including inositol hexakisphosphate binding activity; phosphate ion transmembrane transporter activity; and virus receptor activity. Predicted to be involved in cellular phosphate ion homeostasis; cellular response to phosphate starvation; and phosphate ion transmembrane transport. Predicted to act upstream of or within response to virus. Predicted to be intrinsic component of plasma membrane. Predicted to be active in Golgi apparatus and plasma membrane. Human ortholog(s) of this gene implicated in basal ganglia calcification. Orthologous to human XPR1 (xenotropic and polytropic retrovirus receptor 1).
