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

The role of dimerisation in the cellular trafficking of G-protein-coupled receptors [PDF]

open access: yes, 2010
The concept that G-protein-coupled receptors can exist as homomeric and/or heteromeric complexes is now well established. Despite this, how dynamic such interactions are and if this may be modulated during receptor trafficking remain topics of debate ...

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.

Prediction of Structure, Function, and Spectroscopic Properties of G-Protein-Coupled Receptors: Methods and Applications [PDF]

open access: yes, 2004
G-protein-coupled receptors are of great pharmaceutical interest, comprising the majority of targets for currently marketed drugs. The theme of my thesis is the development of the structure prediction method, MembStruk, for the superfamily of G-protein ...

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 ...

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,

Regulators of G protein signalling proteins in the human myometrium [PDF]

open access: yes, 2009
The contractile state of the human myometrium is controlled by extracellular signals that promote relaxation or contraction. Many of these signals function through G proteincoupled receptors at the cell surface, stimulating heterotrimeric G proteins and ...

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.

On the hierarchical classification of G Protein-Coupled Receptors [PDF]

open access: yes, 2007
Motivation: G protein-coupled receptors (GPCRs) play an important role in many physiological systems by transducing an extracellular signal into an intracellular response. Over 50% of all marketed drugs are targeted towards a GPCR.

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.
