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.

A G-Protein Coupled Receptor and Macular Degeneration

open access: yesCells, 2020
Age-related macular degeneration (AMD) is a leading cause of irreversible blindness in the world. The risk of AMD increases with age and is most common among the white population. Here, we discuss the convergence of factors related to race, pigmentation,

Regulation Role of Non-Rhodopsin G Protein-coupled Receptor Kinases on Tumor

open access: yesZhongliu Fangzhi Yanjiu, 2019
G protein-coupled receptor kinases (GRKs) are involved in a wide range of cellular physiology and pathological activities by specifically phosphorylating activated G-protein coupled receptors (GPCRs) to terminate GPCR signaling and phosphorylating non ...

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.

The Metastasis Suppressor Gene KiSS-1 Encodes Kisspeptins, the Natural Ligands of the Orphan G Protein-coupled Receptor GPR54*

open access: yesJournal of Biological Chemistry, 2001
Natural peptides displaying agonist activity on the orphan G protein-coupled receptor GPR54 were isolated from human placenta. These 54-, 14,- and 13-amino acid peptides, with a common RF-amide C terminus, derive from the product of KiSS-1, a metastasis ...

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.

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

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.

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 ...
