Instability of a class a G protein-coupled receptor oligomer interface.
The quaternary structure of G protein-coupled receptors (GPCRs) can influence their trafficking and ability to transduce signals. GPCR oligomers are generally portrayed as long-lived entities, although the stability of these complexes has not been studied. Here we show that D2 dopamine receptor protomers interact transiently at a specific oligomer interface. Selective immobilization of cyan flu...
متن کاملG-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 کاملApplication of oligomer interface prediction method in Class A G-protein coupled receptors
About 1000 genes encoding GPCRs (G-protein Coupled Receptors) exist in human genome. Over 30% of clinically marketed drugs are active at this family and GPCRs are one of the most important target classes of proteins for drug. Over the past 25 years, the formation of GPCR homo and hetero oligomer has been suggested by biochemical and pharmacological evidence. More recently, it was revealed that ...
متن کاملGPCR-OKB: the G Protein Coupled Receptor Oligomer Knowledge Base
SUMMARY Rapid expansion of available data about G Protein Coupled Receptor (GPCR) dimers/oligomers over the past few years requires an effective system to organize this information electronically. Based on an ontology derived from a community dialog involving colleagues using experimental and computational methodologies, we developed the GPCR-Oligomerization Knowledge Base (GPCR-OKB). GPCR-OKB ...
متن کاملDimerization of the class A G protein-coupled neurotensin receptor NTS1 alters G protein interaction.
G protein-coupled receptors (GPCRs) have been found as monomers but also as dimers or higher-order oligomers in cells. The relevance of the monomeric or dimeric receptor state for G protein activation is currently under debate for class A rhodopsin-like GPCRs. Clarification of this issue requires the availability of well defined receptor preparations as monomers or dimers and an assessment of t...
