Protein Structure

UniProt Annotation

Function

Receptor for the lysosphingolipid sphingosine 1- phosphate (S1P). S1P is a bioactive lysophospholipid that elicits diverse physiological effect on most types of cells and tissues. When expressed in rat HTC4 hepatoma cells, is capable of mediating S1P-induced cell proliferation and suppression of apoptosis. {ECO:0000269PubMed:10617617}.

Subcellular Localization

Cell membrane; Multi-pass membrane protein.

Disease Associations

Tissue Specificity

Expressed in all tissues, but most abundantly in heart, placenta, kidney, and liver.
