Sphingosine-1-phosphate receptor 1 (S1P receptor 1 or S1P1) also known as endothelial differentiation gene 1 (EDG1) is a protein that in humans is encoded the S1PR1 gene. S1PR1 is a G-protein-coupled receptor which binds the bioactive signaling molecule sphingosine 1-phosphate (S1P). S1PR1 belongs to a sphingosine-1-phosphate receptor subfamily comprising five members (S1PR1-5).
