Abstract

Sphingosine-1-phosphate (S1P) binds to and signals through several members of a group of G protein-coupled receptors (GPCRs) known as the S1P/EDG family. Several of these receptors are coexpressed in various cell types and recent reports have shown that biological effects of S1P often require more than one S1P receptor subtype. Recent evidence indicates that many GPCRs exist as dimers. We show that S1P receptors form both homodimers as well as heterodimers with other members of the S1P subfamily of receptors. We also discuss the role that GPCR dimers play in receptor function and what this may mean for S1P signaling.
