High capacity in G protein-coupled receptor signaling [PDF]

open access: yesNature Communications, 2018
G protein-coupled receptors (GPCRs) activate intracellular signalling pathways upon extracellular stimulation. Here authors record single cell responses of GPCR signalling which allows the direct estimation of its channel capacity for each cell along ...

G Protein-Coupled Receptor Kinases Take Central Stage

open access: yesCells, 2022
The relevance of the family of G protein-coupled receptor kinases (GRKs) is based on its key participation in the regulation and intracellular dynamics of the largest family of membrane receptors, namely G protein-coupled receptors (GPCRs) [...]

G Protein–Coupled Receptor Heteromers [PDF]

open access: yesAnnual Review of Pharmacology and Toxicology, 2016
G protein–coupled receptors (GPCRs) compose one of the largest families of membrane proteins involved in intracellular signaling. They are involved in numerous physiological and pathological processes and are prime candidates for drug development. Over the past decade, an increasing number of studies have reported heteromerization between GPCRs.

Allosteric modulation of G protein-coupled receptor signaling

open access: yesFrontiers in Endocrinology, 2023
G protein-coupled receptors (GPCRs), the largest family of transmembrane proteins, regulate a wide array of physiological processes in response to extracellular signals. Although these receptors have proven to be the most successful class of drug targets,

Interaction of the Xanthine Nucleotide Binding Goα Mutant with G Protein-coupled Receptors [PDF]

open access: yes, 1998
We constructed a double mutant version of the α subunit of Go that was regulated by xanthine nucleotides instead of guanine nucleotides (GoαX). We investigated the interaction between GoαX and G protein-coupled receptors in vitro.

Creation of photocyclic vertebrate rhodopsin by single amino acid substitution

open access: yeseLife, 2022
Opsins are universal photoreceptive proteins in animals and can be classified into three types based on their photoreaction properties. Upon light irradiation, vertebrate rhodopsin forms a metastable active state, which cannot revert back to the original

Probing the role of the cation–π interaction in the binding sites of GPCRs using unnatural amino acids [PDF]

open access: yes, 2009
We describe a general application of the nonsense suppression methodology for unnatural amino acid incorporation to probe drug–receptor interactions in functional G protein-coupled receptors (GPCRs), evaluating the binding sites of both the M2 muscarinic

Gi- and Gs-coupled GPCRs show different modes of G-protein binding. [PDF]

open access: yes, 2018
More than two decades ago, the activation mechanism for the membrane-bound photoreceptor and prototypical G protein-coupled receptor (GPCR) rhodopsin was uncovered.

C-terminal threonines and serines play distinct roles in the desensitization of rhodopsin, a G protein-coupled receptor

open access: yeseLife, 2015
Rod photoreceptors generate measurable responses to single-photon activation of individual molecules of the G protein-coupled receptor (GPCR), rhodopsin.

G protein-coupled receptors not currently in the spotlight: free fatty acid receptor 2 and GPR35 [PDF]

open access: yes, 2017
It is widely appreciated that G protein-coupled receptors have been the most successfully exploited class of targets for the development of small molecule medicines. Despite this, to date, less than 15% of the non-olfactory G protein-coupled receptors in
