OGR1 (originally identified as GPR68) is a high-affinity receptor for sphingosylphosphorylcholine (SPC). SPC is a member of a class of bioactive lipids which regulate cellular functions. These functions include cell proliferation and growth inhibition, smooth muscle contration and wound healing. SPC also stimulated signalling pathways that induce tyrosine phosphorylation, activate MAP kinases and protein kinase C, modify ion channel activity and increase intracellular Ca2+ concentration. OGR1 is expressed in placenta, lung, liver, spleen, testis, small intestine and peripheral blood leukocytes. It is not found in thymus, ovary, colon, skeletal muscle, kidney or pancreas.
