domain:Region A confers human cells susceptibility to infection by Gibbon Ape Leukemia Virus (GaLV) and Feline leukemia virus subgroup B (FeLV-B). Substitution of Human SLC20A1 region A by region A of murine SLC20A1 prevents viral infection.,function:Sodium-phosphate symporter which plays a fundamental housekeeping role in phosphate transport, such as absorbing phosphate from interstitial fluid for normal cellular functions such as cellular metabolism, signal transduction, and nucleic acid and lipid synthesis. May play a role in extracellular matrix and cartilage calcification as well as in vascular calcification. May function as a retroviral receptor as it confers human cells susceptibility to infection to Gibbon Ape Leukemia Virus (GaLV), Simian sarcoma-associated virus (SSAV) and Feline leukemia virus subgroup B (FeLV-B) as well as 10A1 murine leukemia virus (10A1 MLV).,induction:By phosphate deprivation as well as by interleukin-8 in hypertrophic chondrocytes.,similarity:Belongs to the inorganic phosphate transporter (PiT) (TC 2.A.20) family.,tissue specificity:Ubiquitously expressed.,
Membrane; Multi-pass membrane protein.
Ubiquitously expressed.
