Quantification of beta adrenergic receptor subtypes in beta-arrestin knockout mouse airways. [PDF]
In allergic asthma Beta 2 adrenergic receptors (β2ARs) are important mediators of bronchorelaxation and, paradoxically, asthma development. This contradiction is likely due to the activation of dual signaling pathways that are downstream of G proteins or

The incidence of candidate binding sites for β-arrestin in Drosophila neuropeptide GPCRs
To support studies of neuropeptide neuromodulation, I have studied beta-arrestin binding sites (BBS’s) by evaluating the incidence of BBS sequences among the C terminal tails (CTs) of each of the 49 Drosophila melanogaster neuropeptide GPCRs.

Impaired recruitment of Grk6 and beta-Arrestin 2 causes delayed internalization and desensitization of a WHIM syndrome-associated CXCR4 mutant receptor. [PDF]
WHIM (warts, hypogammaglobulinemia, infections, and myelokatexis) syndrome is a rare immunodeficiency syndrome linked to heterozygous mutations of the chemokine receptor CXCR4 resulting in truncations of its cytoplasmic tail.

Scaffolding of Mitogen-Activated Protein Kinase Signaling by β-Arrestins
β-arrestins were initially identified to desensitize and internalize G-protein-coupled receptors (GPCRs). Receptor-bound β-arrestins also initiate a second wave of signaling by scaffolding mitogen-activated protein kinase (MAPK) signaling ...

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

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 ...

The Two β-Arrestins Regulate Distinct Metabolic Processes: Studies with Novel Mutant Mouse Models
The two β-arrestins (β-arrestin-1 and -2; alternative names: arrestin-2 and -3, respectively) are well known for their ability to inhibit signaling via G protein-coupled receptors.

On the origins of arrestin and rhodopsin
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.

β-arrestin2 in infiltrated macrophages inhibits excessive inflammation after myocardial infarction. [PDF]
Beta-arrestins (β-arrestin1 and β-arrestin2) are known as cytosolic proteins that mediate desensitization and internalization of activated G protein-coupled receptors.

Desensitization, internalization, and signaling functions of beta-arrestins demonstrated by RNA interference. [PDF]
Beta-arrestins bind to activated G protein-coupled receptor kinase-phosphorylated receptors, which leads to their desensitization with respect to G proteins, internalization via clathrin-coated pits, and signaling via a growing list of "scaffolded ...
