Arrestin, beta 1

beta-arrestin, beta-arrestin 1, arrestin-2, a beta-arrestin
Members of arrestin/beta-arrestin protein family are thought to participate in agonist-mediated desensitization of G-protein-coupled receptors and cause specific dampening of cellular responses to stimuli such as hormones, neurotransmitters, or sensory signals. Arrestin beta 1 is a cytosolic protein and acts as a cofactor in the beta-adrenergic receptor kinase (BARK) mediated desensitization of beta-adrenergic receptors. Besides the central nervous system, it is expressed at high levels in peripheral blood leukocytes, and thus the BARK/beta-arrestin system is believed to play a major role in regulating receptor-mediated immune functions. Alternatively spliced transcripts encoding different isoforms of arrestin beta 1 have been described. [provided by RefSeq, Jan 2011] (from NCBI)

Papers on beta-arrestin
Long Receptor Residence Time of C26 Contributes to Super Agonist Activity at the Human β2 Adrenoceptor.
Charlton et al., Nottingham, United Kingdom. In Mol Pharmacol, Feb 2016
We have further characterised the novel β2 adrenoceptor agonist C26 (7-[(R)-2-((1R,2R)-2-benzyloxycyclopentylamino)-1-hydroxyethyl]-4-hydroxybenzothiazolone), which displays higher intrinsic activity than the endogenous ligand adrenaline in cAMP accumulation, β-arrestin-2 recruitment and receptor internalization assays.
Topical Docosahexaenoic Acid (DHA) Accelerates Skin Wound Healing in Rats and Activates GPR120.
Araújo et al., Campinas, Brazil. In Biol Res Nurs, Feb 2016
Upon DHA topical treatment, wound healing was significantly accelerated and was accompanied by the molecular activation of GPR120, as determined by its association with β-arrestin-2.
In vivo veritas, the next frontier for functionally selective GPCR ligands.
Beaulieu, Canada. In Methods, Feb 2016
In doing so, we placed special attention on strategies allowing to discriminate between G-protein and beta-arrestin mediated mechanisms.
Stalk-dependent and stalk-independent signaling by the adhesion G protein-coupled receptors GPR56 (ADGRG1) and BAI1 (ADGRB1).
Hall et al., United States. In J Biol Chem, Jan 2016
For G1, however, the results were mixed, with the SL mutant exhibiting robust activity in several signaling assays (including TGFα shedding, activation of NFAT luciferase and beta-arrestin recruitment) but reduced activity relative to ΔNT in a distinct assay (activation of SRF luciferase).
KISS1R signaling promotes invadopodia formation in human breast cancer cell via β-arrestin2/ERK.
Bhattacharya et al., London, Canada. In Cell Signal, Jan 2016
However, we have previously shown that in breast cancer cells lacking the estrogen receptor (ERα), kisspeptin-10 stimulates cell migration and invasion by cross-talking with the epidermal growth factor receptor (EGFR), via a β-arrestin-2-dependent mechanism.
Regulation of N-Formyl Peptide Receptor Signaling and Trafficking by Arrestin-Src Kinase Interaction.
Prossnitz et al., Albuquerque, United States. In Plos One, Dec 2015
To better understand the role of Src kinase in this process, in the current study we employed a previously described arrestin-2 (arr2) mutant deficient in Src kinase binding (arr2-P91G/P121E).
Drug Design targeting the CXCR4/CXCR7/CXCL12 pathway.
Zhong et al., Omaha, United States. In Curr Top Med Chem, Oct 2015
The function of CXCR7 is generally considered to be mediated by: (a) recruiting β-arrestin-2; (b) heterodimerizing with CXCR4; and (c) acting as a "scavenger" of CXCL12, thus lowering the level of CXCL12 to weaken the activity of CXCR4.
Treatment of acromegaly in the era of personalized and predictive medicine.
Puig Domingo, Badalona, Spain. In Clin Endocrinol (oxf), Jul 2015
This review will discuss the development of a potential treatment algorithm for acromegaly addressing the biochemical control of the disease as well of its associated comorbidities, under a personalized approach based upon markers of prognostic and predictive significance, such as tumour size, MRI adenoma signal, GH value after acute octreotide test, granular adenoma pattern, Ki-67, somatostatin receptor phenotype, aryl hydrocarbon-interacting protein expression, gsp mutations, RAF kinase activity, E-cadherin and beta-arrestin-1.
Activated protein C: biased for translation.
Mosnier et al., Los Angeles, United States. In Blood, Jun 2015
For these beneficial effects, APC alters cell signaling networks and gene expression profiles by activating protease-activated receptors 1 and 3. APC's activation of these G protein-coupled receptors differs completely from thrombin's activation mechanism due to biased signaling via either G proteins or β-arrestin-2.
Molecular Physiology of Enteric Opioid Receptors.
Akbarali et al., Lansing, United States. In Am J Gastroenterol, 2014
This may be due to differential β-arrestin-2-dependent opioid receptor desensitization and internalization in enteric nerves in the colon compared with the small intestine and in neuronal pain pathways.
Omega-3 fatty acids prevent inflammation and metabolic disorder through inhibition of NLRP3 inflammasome activation.
