G-protein Coupled Receptor Dimerization
A growing body of evidence suggests that GPCRs exist and function as dimers or higher oligomers. The evidence for GPCR dimerization comes from biochemical, biophysical and functional studies. In addition, researchers have shown the occurrence of heterodimerization between different members of the GPCR family. Two receptors can interact with each other to make a dimer through their extracellular...
متن کاملCharacterization of an orphan G protein - coupled receptor , GPR 20 , that constitutively activates
GPR20 was isolated as an orphan G protein-coupled receptor from genomic DNA by PCR amplification. Although GPR20 was closely related to nucleotide or lipid receptors, the functional role of this receptor, as well as its endogenous ligand, remain unclear. Here, we demonstrate that GPR20 is constitutively active in the absence of ligand, leading to continuous activation of its coupled G proteins....
متن کاملEvidence for an interaction of neuronostatin with the orphan G protein-coupled receptor, GPR107.
Neuronostatin, derived from the somatostatin preprohormone, is a recently described peptide that is produced by several tissues involved in cardiovascular regulation and metabolism, including the hypothalamus. Injection of neuronostatin into the lateral cerebroventricle led to a dose-related increase in mean arterial pressure (MAP) in rats. Any attempt to inhibit the production of neuronostati...
متن کاملLactate inhibits lipolysis in fat cells through activation of an orphan G-protein-coupled receptor, GPR81.
Lactic acid is a well known metabolic by-product of intense exercise, particularly under anaerobic conditions. Lactate is also a key source of energy and an important metabolic substrate, and it has also been hypothesized to be a signaling molecule directing metabolic activity. Here we show that GPR81, an orphan G-protein-coupled receptor highly expressed in fat, is in fact a sensor for lactate...
متن کاملAngiogenic sprouting into neural tissue requires Gpr124, an orphan G protein-coupled receptor.
The vasculature of the CNS is structurally and functionally distinct from that of other organ systems and is particularly prone to developmental abnormalities and hemorrhage. Although other embryonic tissues undergo primary vascularization, the developing nervous system is unique in that it is secondarily vascularized by sprouting angiogenesis from a surrounding perineural plexus. This sproutin...
