Distinct cellular and subcellular distributions of G protein-coupled receptor kinase and arrestin isoforms in the striatum. [PDF]

PLoS ONE, 2012
G protein-coupled receptor kinases (GRKs) and arrestins mediate desensitization of G protein-coupled receptors (GPCR). Arrestins also mediate G protein-independent signaling via GPCRs.

Mammalian α arrestins link activated seven transmembrane receptors to Nedd4 family e3 ubiquitin ligases and interact with β arrestins. [PDF]

PLoS ONE, 2012
The complement of fungal cell surface proteins is widely regulated by ubiquitination of membrane proteins, which results in their endocytosis and vacuolar degradation.

Ubiquitin-Mediated Regulation of Endocytosis by Proteins of the Arrestin Family

Biochemistry Research International, 2012
In metazoans, proteins of the arrestin family are key players of G-protein-coupled receptors (GPCRS) signaling and trafficking. Following stimulation, activated receptors are phosphorylated, thus allowing the binding of arrestins and hence an “arrest” of

β-Arrestin-dependent and -independent endosomal G protein activation by the vasopressin type 2 receptor

eLife, 2023
The vasopressin type 2 receptor (V2R) is an essential G protein-coupled receptor (GPCR) in renal regulation of water homeostasis. Upon stimulation, the V2R activates Gαs and Gαq/11, which is followed by robust recruitment of β-arrestins and receptor ...

Distinct G protein-coupled receptor phosphorylation motifs modulate arrestin affinity and activation and global conformation

Nature Communications, 2019
The cellular functions of arrestins are determined in part by the pattern of phosphorylation on the G protein-coupled receptors (GPCRs) to which arrestins bind.

Distinct and shared roles of β-arrestin-1 and β-arrestin-2 on the regulation of C3a receptor signaling in human mast cells. [PDF]

PLoS ONE, 2011
The complement component C3a induces degranulation in human mast cells via the activation of cell surface G protein coupled receptors (GPCR; C3aR).

Quantification of beta adrenergic receptor subtypes in beta-arrestin knockout mouse airways. [PDF]

PLoS ONE, 2015
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

Differential Involvement of ACKR3 C-Tail in β-Arrestin Recruitment, Trafficking and Internalization

Cells, 2021
Background: The atypical chemokine receptor 3 (ACKR3) belongs to the superfamily of G protein-coupled receptors (GPCRs). Unlike classical GPCRs, this receptor does not activate G proteins in most cell types but recruits β-arrestins upon activation. ACKR3

To Be Biased or Not to Be: A Play for G-Protein Coupled Receptors

International Journal of Translational Medicine
G protein-coupled receptors (GPCRs) are the largest family of diverse receptors in eukaryotic organisms, playing a critical role in modulating human physiology. It therefore comes as no surprise that about 36% of all currently available drugs target this
