Regulating G protein-coupled receptors by topological inversion

open access: yeseLife, 2019
G protein-coupled receptors (GPCRs) are a family of proteins containing seven transmembrane helices, with the N- and C-terminus of the protein located at the extracellular space and cytosol, respectively.

Role of G-protein coupled receptors in cardiovascular diseases

open access: yesFrontiers in Cardiovascular Medicine, 2023
Cardiovascular diseases (CVDs) are the leading cause of death globally, with CVDs accounting for nearly 30% of deaths worldwide each year. G-protein-coupled receptors (GPCRs) are the most prominent family of receptors on the cell surface, and play an ...

Evolving the lock to fit the key to create a family of G protein-coupled receptors potently activated by an inert ligand

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2007
We evolved muscarinic receptors in yeast to generate a family of G protein-coupled receptors (GPCRs) that are activated solely by a pharmacologically inert drug-like and bioavailable compound (clozapine-N-oxide).

G-protein-coupled receptor kinases

open access: yesKidney International, 1996
beta-Adrenergic receptors are prototypes of the many G-protein-coupled receptors. Activation and inactivation of these receptors are regulated by multiple mechanisms which can affect either their function or their expression. The most obvious changes of such receptor systems are induced by activation of the receptors themselves by their respective ...

Signal Transduction of Sphingosine-1-Phosphate G Protein—Coupled Receptors

open access: yesThe Scientific World Journal, 2006
Sphingosine-1-phosphate (S1P) is a bioactive lipid capable of eliciting dramatic effects in a variety of cell types. Signaling by this molecule is by a family of five G protein—coupled receptors named S1P1–5 that signal through a variety of pathways to ...

A modeling strategy for G-protein coupled receptors

open access: yesAIMS Biophysics, 2016
Cell responses can be triggered via G-protein coupled receptors (GPCRs) that interact with small molecules, peptides or proteins and transmit the signal over the membrane via structural changes to activate intracellular pathways.

Algebraic study of receptor-ligand systems: a dose-response analysis [PDF]

open access: yesarXiv, 2022
The study of a receptor-ligand system generally relies on the analysis of its dose-response (or concentration-effect) curve, which quantifies the relation between ligand concentration and the biological effect (or cellular response) induced when binding its specific cell surface receptor.

Powdered G-Protein-Coupled Receptors [PDF]

open access: yesThe Journal of Physical Chemistry Letters, 2016
Preparation and storage of functional membrane proteins such as G-protein-coupled receptors (GPCRs) are crucial to the processes of drug delivery and discovery. Here, we describe a method of preparing powdered GPCRs using rhodopsin as the prototype. We purified rhodopsin in CHAPS detergent with low detergent to protein ratio so the bulk of the sample ...

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) [...]
