Visualization of arrestin recruitment by a G-protein-coupled receptor.
G-protein-coupled receptors (GPCRs) are critically regulated by β-arrestins, which not only desensitize G-protein signalling but also initiate a G-protein-independent wave of signalling. A recent surge of structural data ...
Heptahelical receptor signaling: beyond the G protein paradigm.
(J Cell Biol, 1999-05-31)
Beta-agonist- and prostaglandin E1-induced translocation of the beta-adrenergic receptor kinase: evidence that the kinase may act on multiple adenylate cyclase-coupled receptors.
(Proc Natl Acad Sci U S A, 1986-09)
beta-Adrenergic receptor kinase (beta-AR kinase) is a cytosolic enzyme that phosphorylates the beta-adrenergic receptor only when it is occupied by an agonist [Benovic, J. Strasser, R. H., Caron, M. G. & Lefkowitz, R. J. ...
In vivo ventricular gene delivery of a beta-adrenergic receptor kinase inhibitor to the failing heart reverses cardiac dysfunction.
BACKGROUND: Genetic manipulation to reverse molecular abnormalities associated with dysfunctional myocardium may provide novel treatment. This study aimed to determine the feasibility and functional consequences of in vivo ...
beta-arrestin-1 competitively inhibits insulin-induced ubiquitination and degradation of insulin receptor substrate 1.
(Mol Cell Biol, 2004-10)
beta-arrestin-1 is an adaptor protein that mediates agonist-dependent internalization and desensitization of G-protein-coupled receptors (GPCRs) and also participates in the process of heterologous desensitization between ...
Cloning and expression of a human kidney cDNA for an alpha 2-adrenergic receptor subtype.
(Proc Natl Acad Sci U S A, 1988-09)
An alpha 2-adrenergic receptor subtype has been cloned from a human kidney cDNA library using the gene for the human platelet alpha 2-adrenergic receptor as a probe. The deduced amino acid sequence resembles the human platelet ...
beta-Arrestin-mediated PDE4 cAMP phosphodiesterase recruitment regulates beta-adrenoceptor switching from Gs to Gi.
(Proc Natl Acad Sci U S A, 2003-02-04)
Phosphorylation of the beta(2) adrenoreceptor (beta(2)AR) by cAMP-activated protein kinase A (PKA) switches its predominant coupling from stimulatory guanine nucleotide regulatory protein (G(s)) to inhibitory guanine nucleotide ...
Multiple endocytic pathways of G protein-coupled receptors delineated by GIT1 sensitivity.
(Proc Natl Acad Sci U S A, 2000-02-01)
Recently, we identified a GTPase-activating protein for the ADP ribosylation factor family of small GTP-binding proteins that we call GIT1. This protein initially was identified as an interacting partner for the G protein-coupled ...
Role of endocytosis in the activation of the extracellular signal-regulated kinase cascade by sequestering and nonsequestering G protein-coupled receptors.
(Proc Natl Acad Sci U S A, 2000-02-15)
Acting through a number of distinct pathways, many G protein-coupled receptors (GPCRs) activate the extracellular signal-regulated kinase (ERK)/mitogen-activated protein kinase (MAPK) cascade. Recently, it has been shown ...
