REGA-SIGN: Development of a Novel Set of NanoBRET-Based G Protein Biosensors

open access: yesBiosensors, 2023
Despite G protein-coupled receptors (GPCRs) being important theapeutic targets, the signaling properties of many GPCRs remain poorly characterized. GPCR activation primarily initiates heterotrimeric G protein signaling. To detect ligand-induced G protein

Multi-Omics Analysis of Multiple Glucose-Sensing Receptor Systems in Yeast

open access: yesBiomolecules, 2022
The yeast Saccharomyces cerevisiae has long been used to produce alcohol from glucose and other sugars. While much is known about glucose metabolism, relatively little is known about the receptors and signaling pathways that indicate glucose availability.

Multiple endocytic pathways of G protein-coupled receptors delineated by GIT1 sensitivity. [PDF]

open access: yes, 2000
Recently, we identified a GTPase-activating protein for the ADP ribosylation factor family of small GTP-binding proteins that we call GIT1. This protein initially was identified as an interacting partner for the G protein-coupled receptor kinases, and ...

Free fatty acid receptors, G protein‐coupled receptor 120 and G protein‐coupled receptor 40, are essential for oil‐induced gastric inhibitory polypeptide secretion

open access: yesJournal of Diabetes Investigation, 2019
Aims/Introduction Incretin hormone glucose‐dependent insulinotropic polypeptide/gastric inhibitory polypeptide (GIP) plays a key role in high‐fat diet‐induced obesity and insulin resistance.

Receptor Quaternary Organization Explains G Protein-Coupled Receptor Family Structure

open access: yesCell Reports, 2017
The organization of Rhodopsin-family G protein-coupled receptors (GPCRs) at the cell surface is controversial. Support both for and against the existence of dimers has been obtained in studies of mostly individual receptors.

Cryo‐EM structure of G‐protein‐coupled receptor GPR17 in complex with inhibitory G protein

open access: yesMedComm, 2022
GPR17 is a class A orphan G protein‐coupled receptor (GPCR) expressed in neurons and oligodendrocyte progenitors of the central nervous system (CNS). The signalling of GPR17 occurs through the heterotrimeric Gi, but its activation mechanism is unclear ...

G PROTEIN–COUPLED RECEPTOR KINASES [PDF]

open access: yesAnnual Review of Biochemistry, 1998
G protein–coupled receptor kinases (GRKs) constitute a family of six mammalian serine/threonine protein kinases that phosphorylate agonist-bound, or activated, G protein–coupled receptors (GPCRs) as their primary substrates. GRK-mediated receptor phosphorylation rapidly initiates profound impairment of receptor signaling, or desensitization.

Competing G protein‐coupled receptor kinases balance G protein and β‐arrestin signaling

open access: yesMolecular Systems Biology, 2012
Seven‐transmembrane receptors (7TMRs) are involved in nearly all aspects of chemical communications and represent major drug targets. 7TMRs transmit their signals not only via heterotrimeric G proteins but also through β‐arrestins, whose recruitment to ...

Significance of G Protein-Coupled Estrogen Receptor in the Pathophysiology of Irritable Bowel Syndrome, Inflammatory Bowel Diseases and Colorectal Cancer

open access: yesFrontiers in Endocrinology, 2020
The regulatory role of estrogens and nuclear estrogen receptors, i. e., estrogen receptor α and β has been reported in gastrointestinal diseases. However, the contribution of G protein-coupled estrogen receptor, the membrane-bound estrogen receptor, is ...

Molecular mechanism of Gαi activation by non-GPCR proteins with a Gα-Binding and Activating motif [PDF]

open access: yes, 2017
Heterotrimeric G proteins are quintessential signalling switches activated by nucleotide exchange on Gα. Although activation is predominantly carried out by G-protein-coupled receptors (GPCRs), non-receptor guanine-nucleotide exchange factors (GEFs) have
