Sphingosine 1 Phosphate Receptor 3 (S1PR3)

Sphingosine-1-phosphate receptor 3 also known as S1PR3 is a G protein-coupled receptor which binds the lipid signaling molecule sphingosine 1-phosphate (S1P). Hence this receptor is also known as S1P3.This gene encodes a member of the EDG family of receptors, which are G protein-coupled receptors. This protein has been identified as a functional receptor for sphingosine 1-phosphate and likely contributes to the regulation of angiogenesis and vascular endothelial cell function.According to these guidelines, a receptor is to be named with the abbreviation of the natural agonist with the highest potency, followed by a subscripted arabic number. Thus they suggested that the designation EDG3 should be changed to S1P3.
