The protein encoded by this gene is structurally similar to G protein-coupled receptors and is highly expressed in endothelial cells. It binds the ligand sphingosine-1-phosphate with high affinity and high specificity, and suggested to be involved in the processes that regulate the differentiation of endothelial cells. Activation of this receptor induces cell-cell adhesion. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2016]
GeneCards Summary for S1PR1 Gene
S1PR1 (Sphingosine-1-Phosphate Receptor 1) is a Protein Coding gene. Diseases associated with S1PR1 include Autoimmune Encephalitis and Gallbladder Adenocarcinoma. Among its related pathways are Lysosphingolipid and LPA receptors and Peptide ligand-binding receptors. GO annotations related to this gene include G-protein coupled receptor activity and sphingosine-1-phosphate receptor activity. An important paralog of this gene is S1PR3.
UniProtKB/Swiss-Prot for S1PR1 Gene
G-protein coupled receptor for the bioactive lysosphingolipid sphingosine 1-phosphate (S1P) that seems to be coupled to the G(i) subclass of heteromeric G proteins. Signaling leads to the activation of RAC1, SRC, PTK2/FAK1 and MAP kinases. Plays an important role in cell migration, probably via its role in the reorganization of the actin cytoskeleton and the formation of lamellipodia in response to stimuli that increase the activity of the sphingosine kinase SPHK1. Required for normal chemotaxis toward sphingosine 1-phosphate. Required for normal embryonic heart development and normal cardiac morphogenesis. Plays an important role in the regulation of sprouting angiogenesis and vascular maturation. Inhibits sprouting angiogenesis to prevent excessive sprouting during blood vessel development. Required for normal egress of mature T-cells from the thymus into the blood stream and into peripheral lymphoid organs. Plays a role in the migration of osteoclast precursor cells, the regulation of bone mineralization and bone homeostasis (By similarity). Plays a role in responses to oxidized 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphocholine by pulmonary endothelial cells and in the protection against ventilator-induced lung injury.
Sphingosine-1-phosphate (S1P) receptors are a group of G-protein-coupled receptors that are currently divided into five subtypes; S1P1, S1P2, S1P3, S1P4 and S1P5. They are expressed in a wide variety of tissues, with each subtype exhibiting a different cell specificity.
