FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the inorganic phosphate transporter family. The encoded protein is a type 3 sodium-dependent phosphate symporter that plays an important role in phosphate homeostasis by mediating cellular phosphate uptake. The encoded protein also confers susceptibility to viral infection as a gamma-retroviral receptor. Mutations in this gene may play a role in familial idiopathic basal ganglia calcification. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Mar 2012]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit brain calcifications in the thalamus, basal ganglia and cerebral cortex, microgliosis, and a high inorganic phosphate concentration [Pi] in cerebrospinal fluid. [provided by MGI curators]
