| Type: | Family | Name: | G protein-coupled receptor 162 |
| Description: | G protein-coupled receptors (GPCRs) constitute a vast protein family that encompasses a wide range of functions, including various autocrine, paracrine and endocrine processes. They show considerable diversity at the sequence level, on the basis of which they can be separated into distinct groups []. The term clan can be used to describe the GPCRs, as they embrace a group of families for which there are indications of evolutionary relationship, but between which there is no statistically significant similarity in sequence []. The currently known clan members include rhodopsin-like GPCRs (Class A, GPCRA), secretin-like GPCRs (Class B, GPCRB), metabotropic glutamate receptor family (Class C, GPCRC), fungal mating pheromone receptors (Class D, GPCRD), cAMP receptors (Class E, GPCRE) and frizzled/smoothened (Class F, GPCRF) [, , , , ]. GPCRs are major drug targets, and are consequently the subject of considerable research interest. It has been reported that the repertoire of GPCRs for endogenous ligands consists of approximately 400 receptors in humans and mice []. Most GPCRs are identified on the basis of their DNA sequences, rather than the ligand they bind, those that are unmatched to known natural ligands are designated by as orphan GPCRs, or unclassified GPCRs [].The rhodopsin-like GPCRs (GPCRA) represent a widespread protein family that includes hormone, neurotransmitter and light receptors, all of which transduce extracellular signals through interaction with guanine nucleotide-binding (G) proteins. Although their activating ligands vary widely in structure and character, the amino acid sequences of the receptors are very similar and are believed to adopt a common structural framework comprising 7 transmembrane (TM) helices [, , ].Computational methods, including percent identity plots, hydropathy profiles and BLAST, have been used to analyse a gene-rich cluster at human chromosome 12p13 and to compare it with its syntenic region in mouse chromosome 6 [, , ]. Of 6 genes identified, a number were novel receptors, including GPR153 (also known as PGR1) and GPR162 (also known as GRCA) []. GPR153 is a cerebellar target of the Gli1 transcription factor, which is involved in the maintenance and proliferation of grabule neuron precursor cells in the cerebellum, and like GPR162 has a noted role in food uptake and decision making processes [].This entry represents G-protein coupled receptor 162. | Short Name: | GPR162 |
