Previous Symbols for S1PR1 Gene
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. [provided by RefSeq, Jul 2008]
GeneCards Summary for S1PR1 Gene
S1PR1 (Sphingosine-1-Phosphate Receptor 1) is a Protein Coding gene. Among its related pathways are Signaling by GPCR and NF-KappaB Family Pathway. GO annotations related to this gene include G-protein coupled receptor activity and sphingolipid binding. An important paralog of this gene is LPAR1.
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, although they are found at their highest density on leukocytes. S1P receptors couple to different G proteins to mediate a range of biological effects; Gi/o modulates cellular survival, proliferation and motility; G12/13 modulates cytoskeletal remodeling and cell-shape changes and Gq modulates a range of cellular effector functions.
