Role of beta-arrestin 2 downstream of dopamine receptors in the basal ganglia [PDF]

open access: yesFrontiers in Neuroanatomy, 2011
Multifunctional scaffolding protein beta-arrestins (βArr) and the G protein receptor kinases (GRK) are involved in the desensitization of several G protein coupled-receptors (GPCR).

Beta-arrestin 1 regulation of reward-motivated behaviors and glutamatergic function. [PDF]

open access: yesPLoS ONE, 2017
The two highly homologous non-visual arrestins, beta-arrestin 1 and 2, are ubiquitously expressed in the central nervous system, yet knowledge of their disparate roles is limited.

The constitutively active V2 receptor mutants conferring NSIAD are weakly sensitive to agonist and antagonist regulation. [PDF]

open access: yesPLoS ONE, 2009
Patients having the nephrogenic syndrome of inappropriate antidiuresis present either the R137C or R137L V2 mutated receptor. While the clinical features have been characterized, the molecular mechanisms of functioning of these two mutants remain elusive.

G Protein-Dependent Activation of the PKA-Erk1/2 Pathway by the Striatal Dopamine D1/D3 Receptor Heteromer Involves Beta-Arrestin and the Tyrosine Phosphatase Shp-2

open access: yesBiomolecules, 2023
The heteromer composed of dopamine D1 and D3 receptors (D1R–D3R) has been defined as a structure able to trigger Erk1/2 and Akt signaling in a G protein-independent, beta-arrestin 1-dependent way that is physiologically expressed in the ventral striatum ...

Physiological and pharmacological implications of beta-arrestin regulation [PDF]

open access: yesPharmacology & Therapeutics, 2009
G protein-coupled receptor-targeted drug discovery as well as "compound reassessment" requires the utilization of diverse screens to determine agonist efficacies and potencies beyond the scope of ligand binding and G protein coupling. Such efforts have arisen from extensive studies, both in cellular and animal models, demonstrating that these seven ...

β-arrestin2 in infiltrated macrophages inhibits excessive inflammation after myocardial infarction. [PDF]

open access: yesPLoS ONE, 2013
Beta-arrestins (β-arrestin1 and β-arrestin2) are known as cytosolic proteins that mediate desensitization and internalization of activated G protein-coupled receptors.

On the origins of arrestin and rhodopsin

open access: yesBMC Evolutionary Biology, 2008
Background G protein coupled receptors (GPCRs) are the most numerous proteins in mammalian genomes, and the most common targets of clinical drugs. However, their evolution remains enigmatic.

Beta-Arrestin-Mediated Signaling in the Heart

open access: yesCirculation Journal, 2008
Beta-arrestin is a multifunctional adapter protein well known for its role in G-protein-coupled receptor (GPCR) desensitization. Exciting new evidence indicates that beta-arrestin is also a signaling molecule capable of initiating its own G-protein-independent signaling at GPCRs.

Polypeptide variants of beta-arrestin and arrestin3

open access: yesJournal of Biological Chemistry, 1993
Retinal arrestin (S-antigen) inactivates the phototransduction cascade by binding to light-activated phosphorylated rhodopsin and thereby "arresting" coupling to the G protein transducin. beta-Arrestin (beta arr), a ubiquitous arrestin homolog, acts analogously to desensitize the beta 2-adrenergic receptor by disrupting Gs receptor interaction.

Triphenylmethane Dye Activation of Beta-Arrestin

open access: yesBiochemistry, 2013
β-Arrestins regulate G protein-coupled receptor signaling as competitive inhibitors and protein adaptors. Low molecular weight biased ligands that bind receptors and discriminate between the G protein dependent arm and β-arrestin, clathrin-associated arm of receptor signaling are considered therapeutically valuable as a result of this distinctive ...
