G protein coupled receptor in apoptosis and apoptotic cell clearance [PDF]

FASEB BioAdvances
Apoptosis is a genetically programmed form of cell death that is substantially conserved across the evolutionary tree. Apoptotic cell elimination includes recognition, phagocytosis, and degradation. Failure to clear apoptotic cells can ultimately cause a

The Open Question of How GPCRs Interact with GPCR Kinases (GRKs)

Biomolecules, 2021
G protein-coupled receptors (GPCRs), which regulate a vast number of eukaryotic processes, are desensitized by various mechanisms but, most importantly, by the GPCR kinases (GRKs).

DEER Analysis of GPCR Conformational Heterogeneity

Biomolecules, 2021
G protein-coupled receptors (GPCRs) represent a large class of transmembrane helical proteins which are involved in numerous physiological signaling pathways and therefore represent crucial pharmacological targets.

G Protein-Coupled Receptor Kinases Take Central Stage

Cells, 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) [...]

Allosteric modulation of G protein-coupled receptor signaling

Frontiers 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,

Creation of photocyclic vertebrate rhodopsin by single amino acid substitution

eLife, 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

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

, 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.

Both Ligand- and Cell-Specific Parameters Control Ligand Agonism in a Kinetic Model of G Protein–Coupled Receptor Signaling [PDF]

, 2007
G protein–coupled receptors (GPCRs) exist in multiple dynamic states (e.g., ligand-bound, inactive, G protein–coupled) that influence G protein activation and ultimately response generation. In quantitative models of GPCR signaling that incorporate these

GPER-induced signaling is essential for the survival of breast cancer stem cells. [PDF]

, 2020
G protein-coupled estrogen receptor-1 (GPER), a member of the G protein-coupled receptor (GPCR) superfamily, mediates estrogen-induced proliferation of normal and malignant breast epithelial cells.

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

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