  • Target

    • 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.
    • Tissue specificity

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

      Belongs to the G-protein coupled receptor 1 family.
    • Cellular localization

      Cell membrane.
