The G-protein-coupled receptor (GPCR) superfamily comprises an estimated 600–1,000 members and is the largest known class of molecular targets with proven therapeutic value. With this background on the structure and general properties of the GPCRs and the G-proteins, we can now look at what happens when a signal arrives at the cell surface and binds to a GPCR. The binding of a signal molecule by the extracellular part of the G-protein linked receptor causes the cytosolic tail of the receptor to interact with, and alter the conformation of, a G-protein. G-protein coupled receptor (GPCR): β -adrenergic signalling pathway G-protein coupled receptors (GPCRs) G protein–coupled receptors (GPCRs) are receptors that are closely related with a member of the guanosine nucleotide–binding protein (G protein) family. The signal transduction through GPCRs are defined by three essential components:. a plasma membrane receptor with seven transmembrane Emerging findings disclose unexpected components of G protein-coupled receptor (GPCR) signaling and cell biology.
Distinct phosphorylation sites in a prototypical GPCR differently orchestrate β-arrestin interaction, Aug 29, 2012 BRET biosensors that have been developed to investigate biology, pharmacology, and signaling of G protein-coupled receptors (GPCRs). Since GPCRs are integral membrane proteins, interaction of membrane lipids with them constitutes an important area of research in GPCR biology.
Chemical and synthetic biology approaches to understand GPCR dynamics. GPCRs are highly dynamic receptors and conformational flexibility is a key determinant of their multimodal signaling scheme.

Recent developments hint at roles for GPCRs in the EV life cycle and, conversely, at roles for EVs in GPCR signal transduction. We highlight key points of convergence, discuss their relevance to current GPCR and EV paradigms, and speculate on how this intersection could lend itself to future therapeutic avenues. 2019-11-25

The binding of a signal molecule by the extracellular part of the G-protein linked receptor causes the cytosolic tail of the receptor to interact with, and alter the conformation of, a G-protein. This has two consequences: First, the alpha subunit of the G- protein loses its GDP and binds a GTP instead.
