Anti-SLC20A1 antibodies are used in the immunodetection of the protein solute carrier family 20 member 1. In humans, the canonical protein has a reported length of 679 amino acid residues and a mass of 73.7 kDa. Its subcellular localization is in the cell membrane. It is ubiquitously expressed across many tissue types. A member of the Inorganic phosphate transporter (PiT) (TC 2.A.20) protein family, SLC20A1 is reported to be a 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. Synonyms for this target antigen include Glvr-1, PIT1, PiT-1, sodium-dependent phosphate transporter 1, gibbon ape leukemia virus receptor 1, and GLVR1. SLC20A1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
