Here are recombinant proteins for S1PR1, the approved symbol for the human gene, 'sphingosine-1-phosphate receptor 1'. With a Uniprot ID of P21453, this protein is listed as having 382 residues in length and a mass of 42.9 kDa. The following protein function has been assigned: 'G-protein coupled receptor for the bioactive lysosphingolipid sphingosine 1-phosphate (S1P) that seems to be coupled to the G(i) subclass of heteromeric G proteins.' A subcellular localization as 'cell membrane' is noted. Orthologs are reported in these species: mouse, rat, zebrafish, chimpanzee, guinea pig. S1PR1 may also be known by other designations: 'sphingosine 1-phosphate receptor 1, S1P receptor 1, S1P receptor Edg-1, endothelial differentiation G-protein coupled receptor 1, endothelial differentiation, sphingolipid G-protein-coupled receptor, 1, sphingosine 1-phosphate receptor EDG1, sphingosine 1-phosphate receptor Edg-1'.
