Sphingosine 1-phosphate (S1P) is a bioactive lipid that binds to and activates a family of GPCRs, S1P1-5 (also known as EDG receptors). Interactions between S1P and its receptors mediate cytoskeletal rearrangement and cell migration, with functional consequences in angiogenesis, lymphocyte trafficking, and smooth muscle development. S1P1 (Edg-1) signals exclusively through Gi, whereas S1P2 (Edg-5) and S1P3 (Edg-3) activate Gi, Gq and G12/13. Although S1P1 and S1P3 promote cell migration, S1P2 inhibits cell migration in several cell types; these opposing functions appear to result from differences in the ability of each receptor to activate Gi. Studies with knockout mice indicate that S1P2 and S1P3 have redundant functions in maintaining vascular integrity during embryonic development.
