β-Arrestin-dependent deactivation of mouse melanopsin.
In mammals, the expression of the unusual visual pigment, melanopsin, is restricted to a small subset of intrinsically photosensitive retinal ganglion cells (ipRGCs), whose signaling regulate numerous non-visual functions including sleep, circadian ...

Differential β-arrestin2 requirements for constitutive and agonist-induced internalization of the CB1 cannabinoid receptor [PDF]
CB1 cannabinoid receptor (CB1R) undergoes both constitutive and agonist-induced internalization, but the underlying mechanisms of these processes and the role of beta-arrestins in the regulation of CB1R function are not completely understood.

Distinct phosphorylation clusters determines the signalling outcome of the free fatty acid receptor FFA4/GPR120 [PDF]
It is established that long-chain free fatty acids including ω-3 fatty acids mediate an array of biological responses through members of the free fatty acid receptor family, which includes FFA4.

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

Surfactant protein-A modulates LPS-induced TLR4 localization and signaling via β-arrestin 2. [PDF]
The soluble C-type lectin surfactant protein (SP)-A mediates lung immune responses partially via its direct effects on alveolar macrophages (AM), the main resident leukocytes exposed to antigens. SP-A modulates the AM threshold of lipopolysaccharide (LPS)

β-Arrestin1 and 2 differentially regulate PACAP-induced PAC1 receptor signaling and trafficking. [PDF]
A pituitary adenylate cyclase-activating polypeptide (PACAP)-specific receptor, PAC1R, is coupled with multiple signal transduction pathways including stimulation of adenylate cyclase, phospholipase C and extracellular-signal regulated kinase (ERK)1/2 ...

Identification of chemokine receptors as potential modulators of endocrine resistance in oestrogen receptor–positive breast cancers [PDF]
Introduction Endocrine therapies target oestrogenic stimulation of breast cancer (BC) growth, but resistance remains problematic. Our aims in this study were (1) to identify genes most strongly associated with resistance to endocrine therapy by ...

Arrestin-biased AT1R agonism induces acute catecholamine secretion through TRPC3 coupling
Angiotensin II type 1 receptor (AT1R)-mediated acute catecholamine release is modulated by β-arrestin. Here the authors show that β-arrestin-1 recruits the Ca2+channel TRPC3 and the PLCγ to the AT1R-β-arrestin complex, triggering G protein-independent ...

The Effects of Apelin and Elabela Ligands on Apelin Receptor Distinct Signaling Profiles
Apelin and Elabela are endogenous peptide ligands for Apelin receptor (APJ), a widely expressed G protein-coupled receptor. They constitute a spatiotemporal dual ligand system to control APJ signal transduction and function.
