ID:GP126_HUMAN DESCRIPTION: RecName: Full=G-protein coupled receptor 126; AltName: Full=Developmentally regulated G-protein-coupled receptor; AltName: Full=Vascular inducible G protein-coupled receptor; Flags: Precursor; FUNCTION: Orphan receptor. May be required for normal differentiation of promyelinating Schwann cells and for normal myelination of axons. Signals probably through G-proteins to transiently elevate cAMP levels (By similarity). SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein. Note=Detected on the cell surface of activated but not resting umbilical vein. TISSUE SPECIFICITY: Expressed in placenta and to a lower extent in pancreas and liver. Detected in aortic endothelial cells but not in skin microvascular endothelial cells. INDUCTION: Up-regulated by bacterial lipopolysaccharides (LPS) and thrombin, but not by other inflammatory stimuli in primary umbilical veins. PTM: Proteolytically cleaved into 2 conserved sites: one in the GPS domain (S1 site) and the other in the middle of the extracellular domain (S2 site). The proteolytic cleavage at S1 site generates an extracellular subunit and a seven-transmembrane subunit. Furin is involved in the cleavage of the S2 site generating a soluble fragment. Processing at the GPS domain occurred independent of and probably prior to the cleavage at the S2 site. POLYMORPHISM: Genetic variations in GPR126 influences stature as a quantitative trait (STQTL) [MIM:606255]. Adult height is an easily observable and highly heritable complex continuous trait. Because of this, it is a model trait for studying genetic influence on quantitative traits. SIMILARITY: Belongs to the G-protein coupled receptor 2 family. LN-TM7 subfamily. SIMILARITY: Contains 1 CUB domain. SIMILARITY: Contains 1 GPS domain. SIMILARITY: Contains 1 pentaxin domain. SEQUENCE CAUTION: Sequence=AAO13250.1; Type=Miscellaneous discrepancy; Note=Sequencing errors; Sequence=BAB55406.1; Type=Erroneous initiation; Sequence=BAC11393.1; Type=Erroneous initiation; Sequence=CAE45930.1; Type=Erroneous initiation; Sequence=CAI20053.1; Type=Erroneous gene model prediction;
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.

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.
