Unexpectedly, Class A G protein-coupled receptors (GPCRs), a large class of signaling proteins exemplified transbilayer lipid movement, conceptualized as the swiping of a credit card (lipid) through a card reader (GPCR Conformational changes that facilitate scrambling are distinct from those associated with GPCR signaling In this review, we discuss the physiological significance of GPCR scramblase activity and the modes of

all cytomegalovirus (CMV) genomes analysed to date is the presence of G protein-coupled receptors (GPCR IMPORTANCE G protein-coupled receptors (GPCRs) act as cell surface molecular "switches" which regulate All cytomegalovirus (CMV) genomes analysed to date possess GPCR homologs with phylogenetic evidence for The mouse CMV (MCMV) GPCR homolog, designated M33, is important for cell-associated virus spread and The signalling repertoire of M33 is distinct from cellular GPCRs and little is known of the relevance

Currently, attention was mainly paid to biased signaling modulators targeting G protein-coupled receptors (GPCRs The biased signaling modulation of non-GPCR receptors has yet to be exploited. Toll-like receptor 4 (TLR4) is one such non-GPCR receptor, which involves MyD88-dependent and TRIF-dependent modulators of TLR4 would provide insight for the future development of biased modulators for other non-GPCR

this study was to identify Gα proteins mediating function of neuronal G protein-coupled receptors (GPCRs Some neuronal GPCRs (such as GTR-1, DCAR-1, DOP-2, NPR-8, NPR-12, NPR-9, and DAF-37) functioned upstream of GOA-1, some neuronal GPCRs (such as DCAR-1, DOP-2, NPR-9, NPR-8, and DAF-37) functioned upstream of GSA-1, and some neuronal GPCRs (such as DOP-2, NPR-8, DAF-37, and DCAR-1) functioned upstream of GPA Our results provide clues for understanding the important function of GPCRs-Gα signaling cascade in the

Class B G protein-coupled receptors (GPCRs) are notoriously difficult to target by small molecules because Using the parathyroid hormone type 1 receptor (PTHR) as a prototypic class B GPCR target, and a combination precise druggable sites and identify allosteric modulators of PTHR signaling that could be extended to GPCRs

allosteric binding site (IABS) has recently been identified at several G protein-coupled receptors (GPCRs To chemically induce CCR9 degradation, we then developed the first PROTAC targeting the IABS of GPCRs our CCR9-PROTAC is able to reduce CCR9 levels, thereby offering an unprecedented approach to modulate GPCR

molecular recognition of two peptidyl mating pheromones by their corresponding G-protein coupled receptors (GPCRs Here, we investigated the stringency of the two GPCRs, Mam2 and Map3, for their respective pheromones First, we switched GPCRs between S. pombe and the closely related species Schizosaccharomyces octosporus Thus, the differences in these two GPCRs might reflect the significantly distinct stringency/flexibility

ligand-binding and signaling patterns, by modulating ligand binding, as well as G-protein coupling or interaction Further difficulties arise from the existence of cross-reactivity with other GPCRs and differences in of chemokine receptors which are regulated by globular protein ligands, unlike most of the class A GPCRs These larger interfaces represent the typical protein-protein interactions which are difficult to modulate . 2009; Wang and Norcross 2008); and are also too small to be engaged by antibodies, which can only interact

vasoconstrictors, resulting in enhanced signalling through their cognate G protein-coupled receptors (GPCR Prolonged vasoconstrictor GPCR signalling increases arterial contraction and stimulates signalling pathways GPCR signalling through phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) promotes VSMC proliferation In VSMC, G protein-coupled receptor kinase 2 (GRK2) is known to regulate numerous vasoconstrictor GPCRs

Several neurotransmitters and neuromodulators, acting through G-protein-coupled receptors (GPCRs), fine-tune However, intracellular partners linking GPCRs to TASK1 modulation are not yet well-known.

Mutations in G protein-coupled receptors (GPCRs) underlie numerous diseases. Pharmacological chaperones are cell-permeant small molecules that engage nascent mutant GPCRs in the These findings aid in advancing the understanding of the effects of genetic mutations on GPCR function

G protein-coupled receptors (GPCRs) transmit extracellular signals to the inside by activation of intracellular In order to avoid interference between these interactions, we studied GRK2 binding in the presence of measured substantial differences in the agonist efficacies to induce M3R-arrestin3 versus M3R-GRK2 interaction However, the rank order of the agonists for G protein- and GRK2-M3R interaction was the same, suggesting
