Description: sphingosine-1-phosphate receptor 1 RefSeq Summary (NM_001400): 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]. Transcript (Including UTRs) Position: hg18 chr1:101,474,893-101,479,664 Size: 4,772 Total Exon Count: 2 Strand: + Coding Region Position: hg18 chr1:101,477,129-101,478,277 Size: 1,149 Coding Exon Count: 1
ID:S1PR1_HUMAN DESCRIPTION: RecName: Full=Sphingosine 1-phosphate receptor 1; Short=S1P receptor 1; Short=S1P1; AltName: Full=Endothelial differentiation G-protein coupled receptor 1; AltName: Full=Sphingosine 1-phosphate receptor Edg-1; Short=S1P receptor Edg-1; AltName: CD_antigen=CD363; 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. This inducible epithelial cell G-protein-coupled receptor may be involved in the processes that regulate the differentiation of endothelial cells. Seems to be coupled to the G(i) subclass of heteromeric G proteins. SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein. TISSUE SPECIFICITY: Endothelial cells, and to a lesser extent, in vascular smooth muscle cells, fibroblasts, melanocytes, and cells of epithelioid origin. INDUCTION: By the tumor promoter phorbol 12-myristate 13-acetate (PMA) in the presence of cycloheximide. PTM: S1P-induced endothelial cell migration requires the PKB/AKT1- mediated phosphorylation of the third intracellular loop at the Thr-236 residue. SIMILARITY: Belongs to the G-protein coupled receptor 1 family.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.
ModBase Predicted Comparative 3D Structure on P21453
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
