The SREB (Super Conserved Receptor Expressed in Brain) are a group of related G-protein coupled receptors. [1] Since no endogenous ligands have yet been identified for these receptors, they are classified as orphan receptors.
In biochemistry, an orphan receptor is a protein that has a similar structure to other identified receptors but whose endogenous ligand has not yet been identified. If a ligand for an orphan receptor is later discovered, the receptor is referred to as an "adopted orphan". Conversely, the term orphan ligand refers to a biological ligand whose cognate receptor has not yet been identified.
There are two known parathyroid hormone receptors in mammals termed PTH1R and PTH2R. These receptors bind parathyroid hormone and are members of the GPCR family of transmembrane proteins.
There are three known mammalian tachykinin receptors termed NK1, NK2 and NK3. All are members of the 7 transmembrane G-protein coupled receptor family and induce the activation of phospholipase C, producing inositol triphosphate (so called Gq-coupled).
The Gs alpha subunit is a heterotrimeric G protein subunit that activates the cAMP-dependent pathway by activating adenylyl cyclase. It is one of the three main families of G proteins: Gαi/Gαo, Gαq, and Gαs. A mnemonic for remembering this subunit is to look at the first letter.
The EGF module-containing Mucin-like hormone Receptors (EMRs) are closely related subgroup of G protein-coupled receptors (GPCRs). These receptors have a unique hybrid structure in which an extracellular epidermal growth factor (EGF)-like domain is fused to a GPCR domain through a mucin-like stalk. There are four variants of EMR labeled 1-4, each encoded by a separate gene. These receptors are predominantly expressed in cells of the immune system and bind ligands such as CD55.
The prokineticin receptor is a G protein-coupled receptor which binds the peptide hormone prokineticin. There are two variants each encoded by a different gene. These receptors mediate gastrointestinal smooth muscle contraction and angiogenesis.
The free fatty acid receptor is a G-protein coupled receptor which binds free fatty acids. There are four variants of the receptor, each encoded by a separate gene. Preliminary findings suggest that FFAR2 and FFAR3 may interact to form a FFAR2-FFAR3 receptor heteromer.
The Retinoic Acid-Inducible orphan G-protein-coupled receptors (RAIG) are a group of four closely related G protein-coupled receptors whose expression is induced by retinoic acid.
The MAS1 oncogene is a G protein-coupled receptor which binds the angiotensin-II metabolite Angiotensin (1-7). The MAS1 receptor when activated by binding angiotensin-(1-7) opposes many of the effects of angiotensin-II activated angiotensin receptor. Hence MAS1 receptor agonists have similar therapeutic effects as angiotensin-II receptor antagonists including lowering blood pressure.
The neuropeptide B/W receptors are members of the G-protein coupled receptor superfamily of integral membrane proteins which bind the neuropeptides B and W. These receptors are predominantly expressed in the CNS and have a number of functions including regulation of the secretion of cortisol.
GPCR neuropeptide receptors are G-protein coupled receptors which bind various neuropeptides. Members include:
The prolactin-releasing peptide receptor (PrRPR) also known as G-protein coupled receptor 10 (GPR10) is a protein that in humans is encoded by the PRLHR gene.
Probable G-protein coupled receptor 27 is a protein that in humans is encoded by the GPR27 gene.
Probable G-protein coupled receptor 173 is a protein that in humans is encoded by the GPR173 gene.
Relaxin/insulin-like family peptide receptor 4, also known as RXFP4, is a human G-protein coupled receptor.
Probable G-protein coupled receptor 85 is a protein that in humans is encoded by the GPR85 gene.
Olfactory receptor 2T10 is a protein that in humans is encoded by the OR2T10 gene.
Olfactory receptor 6T1 is a protein that in humans is encoded by the OR6T1 gene.
Olfactory receptor 4M2 is a protein that in humans is encoded by the OR4M2 gene.
Olfactory receptor 2T27 is a protein that in humans is encoded by the OR2T27 gene.
The leukotriene (LT) receptors are G protein-coupled receptors that bind and are activated by the leukotrienes. They include the following proteins:
Medical Subject Headings (MeSH) is a comprehensive controlled vocabulary for the purpose of indexing journal articles and books in the life sciences; it serves as a thesaurus that facilitates searching. Created and updated by the United States National Library of Medicine (NLM), it is used by the MEDLINE/PubMed article database and by NLM's catalog of book holdings. MeSH is also used by ClinicalTrials.gov registry to classify which diseases are studied by trials registered in ClinicalTrials.
