Light intensity-dependent arrestin switching for inactivation of a light-sensitive GPCR, bistable opsin [PDF]

iScience
Summary: Inactivation of most light-sensitive G protein-coupled receptor (GPCR) opsins involves arrestin binding to terminate cell responses. In the zebrafish pineal organ, UV sensitive parapinopsin 1 (PP1)-expressing cells exhibit color opponency ...

Historical Perspective of the G Protein-Coupled Receptor Kinase Family

Cells, 2021
Agonist activation of G protein-coupled receptors promotes sequential interaction of the receptor with heterotrimeric G proteins, G protein-coupled receptor kinases (GRKs), and arrestins. GRKs play a central role in mediating the switch from G protein to

The Atypical Chemerin Receptor GPR1 Displays Different Modes of Interaction with β-Arrestins in Humans and Mice with Important Consequences on Subcellular Localization and Trafficking

Cells, 2022
Atypical chemokine receptors (ACKRs) have emerged as a subfamily of chemokine receptors regulating the local bioavailability of their ligands through scavenging, concentration, or transport.

Interactions between β-arrestin proteins and the cytoskeletal system, and their relevance to neurodegenerative disorders

Frontiers in Endocrinology, 2023
β-arrestins, which have multiple cellular functions, were initially described as proteins that desensitize rhodopsin and other G protein-coupled receptors.

TORC1 Signaling Controls the Stability and Function of α-Arrestins Aly1 and Aly2

Biomolecules, 2022
Nutrient supply dictates cell signaling changes, which in turn regulate membrane protein trafficking. To better exploit nutrients, cells relocalize membrane transporters via selective protein trafficking.

Endothelial β‐arrestins regulate mechanotransduction by the type II bone morphogenetic protein receptor in primary cilia

Pulmonary Circulation, 2022
Modulation of endothelial cell behavior and phenotype by hemodynamic forces involves many signaling components, including cell surface receptors, intracellular signaling intermediaries, transcription factors, and epigenetic elements.

Differential Regulation of GPCRs—Are GRK Expression Levels the Key?

Frontiers in Cell and Developmental Biology, 2021
G protein-coupled receptors (GPCRs) comprise the largest family of transmembrane receptors and their signal transduction is tightly regulated by GPCR kinases (GRKs) and β-arrestins.

ACKR4 Recruits GRK3 Prior to β-Arrestins but Can Scavenge Chemokines in the Absence of β-Arrestins

Frontiers in Immunology, 2020
Chemokines are essential for guiding cell migration. Atypical chemokine receptors (ACKRs) contribute to the cell migration process by binding, internalizing and degrading local chemokines, which enables the formation of confined gradients.

RNAi targeting Caenorhabditis elegans α-arrestins has small or no effects on lifespan [version 2; referees: 2 approved, 1 approved with reservations]

F1000Research, 2017
Background: α-arrestins are a family of proteins that are implicated in multiple biological processes, including metabolism and receptor desensitization.

c-Src regulates Akt signaling in response to ghrelin via beta-arrestin signaling-independent and -dependent mechanisms. [PDF]

PLoS ONE, 2009
The aim of the present study was to identify the signaling mechanisms to ghrelin-stimulated activation of the serine/threonine kinase Akt. In human embryonic kidney 293 (HEK293) cells transfected with GHS-R1a, ghrelin leads to the activation of Akt ...
