Probable G-protein coupled receptor 75 is a protein that in humans is encoded by the GPR75 gene. [5] [6]
GPR75 is a member of the G protein-coupled receptor family. GPRs are cell surface receptors that activate guanine-nucleotide binding proteins upon the binding of a ligand. [6]
GPR75 is currently classified as an orphan GPCR and several studies are underway to identify its ligand. In one study, the chemokine CCL5 (RANTES) has been shown to stimulate calcium mobilization and inositol triphosphate formation in GPR75-transfected cells. [7]
A 2021 study reported that people with protein-truncating variants of GPR75 were associated with 5.3kg lower body weight and 54% lower odds for obesity. GPR75 knock-out mice showed resistance to weight gain under high-fat diet. [8]
Chemokine ligand 5 is a protein which in humans is encoded by the CCL5 gene. The gene has been discovered in 1990 by in situ hybridisation and it is localised on 17q11.2-q12 chromosome. It is also known as RANTES. RANTES was first described by Dr. Tom Schall who named the protein, the original source of the name Rantes was from the Argentine movie Man Facing Southeast about an alien who shows up in a mental ward who was named Rantés, the rather clunky acronym was only made to fit the name.
The KiSS1-derived peptide receptor is a G protein-coupled receptor which binds the peptide hormone kisspeptin (metastin). Kisspeptin is encoded by the metastasis suppressor gene KISS1, which is expressed in a variety of endocrine and gonadal tissues. Activation of the kisspeptin receptor is linked to the phospholipase C and inositol trisphosphate second messenger cascades inside the cell.
G protein-coupled receptor 6, also known as GPR6, is a protein which in humans is encoded by the GPR6 gene.
Neuropeptides B/W receptor 1, also known as NPBW1 and GPR7, is a human protein encoded by the NPBWR1 gene. As implied by its name, it and related gene NPBW2 are transmembranes protein that bind Neuropeptide B (NPB) and Neuropeptide W (NPW), both proteins expressed strongly in parts of the brain that regulate stress and fear including the extended amygdala and stria terminalis. When originally discovered in 1995, these receptors had no known ligands and were called GPR7 and GPR8, but at least three groups in the early 2000s independently identified their endogenous ligands, triggering the name change in 2005.
Neuropeptides B/W receptor 2, also known as NPBW2, is a human protein encoded by the NPBWR2 gene.
Probable G-protein coupled receptor 12 is a protein that in humans is encoded by the GPR12 gene.
Uracil nucleotide/cysteinyl leukotriene receptor is a G protein-coupled receptor that in humans is encoded by the GPR17 gene located on chromosome 2 at position q21. The actual activating ligands for and some functions of this receptor are disputed.
G-protein coupled receptor 31 also known as 12-(S)-HETE receptor is a protein that in humans is encoded by the GPR31 gene. The human gene is located on chromosome 6q27 and encodes a G-protein coupled receptor protein composed of 319 amino acids.
Probable G-protein coupled receptor 52 is a protein that in humans is encoded by the GPR52 gene.
Neuropeptide FF receptor 2, also known as NPFF2 is a human protein encoded by the NPFFR2 gene.
2-Oxoglutarate receptor 1 (OXGR1), also known as cysteinyl leukotriene receptor E (CysLTE) and GPR99, is a protein that in humans is encoded by the OXGR1 gene. The Gene has recently been nominated as a receptor not only for 2-oxogluterate but also for the three cysteinyl leukotrienes (CysLTs), particularly leukotriene E4 (LTE4) and to far lesser extents LTC4 and LTE4. Recent studies implicate GPR99 as a cellular receptor which is activated by LTE4 thereby causing these cells to contribute to mediating various allergic and hypersensitivity responses.
Probable G-protein coupled receptor 84 is a protein that in humans is encoded by the GPR84 gene.
Probable G-protein coupled receptor 158 (GPR158), also known as the metabotropic glycine receptor (mGlyR), is a protein that in humans is encoded by the GPR158 gene.
Pyroglutamylated RFamide peptide receptor also known as orexigenic neuropeptide QRFP receptor or G-protein coupled receptor 103 (GPR103) is a protein that in humans is encoded by the QRFPR gene.
G protein-coupled receptor 119 also known as GPR119 is a G protein-coupled receptor that in humans is encoded by the GPR119 gene.
GPR156, is a human gene which encodes a G protein-coupled receptor belonging to metabotropic glutamate receptor subfamily. By sequence homology, this gene was proposed as being a possible GABAB receptor subunit, however when expressed in cells alone or with other GABAB subunits, no response to GABAB ligands could be detected. Therefore, the function of this protein remains to be elucidated. In vitro studies on GPR156 constitutive activity revealed a high level of basal activation and coupling with members of the Gi/Go heterotrimeric G protein family.
G-protein coupled receptor 97 also known as adhesion G protein-coupled receptor G3 (ADGRG3) is a protein that in humans is encoded by the ADGRG3 gene. GPR97 is a member of the adhesion GPCR family. Adhesion GPCRs are characterized by an extended extracellular region often possessing N-terminal protein modules that is linked to a TM7 region via a domain known as the GPCR-Autoproteolysis INducing (GAIN) domain.
G-protein coupled receptor 3 is a protein that in humans is encoded by the GPR3 gene. The protein encoded by this gene is a member of the G protein-coupled receptor family of transmembrane receptors and is involved in signal transduction.
G protein-coupled receptor 50 is a protein which in humans is encoded by the GPR50 gene.
NPW is a gene that in humans encodes Neuropeptide W protein.
