Functionally active targeting domain of the beta-adrenergic receptor kinase: an inhibitor of G beta gamma-mediated stimulation of type II adenylyl cyclase.
(Proc Natl Acad Sci U S A, 1994-04-26)
The beta-adrenergic receptor kinase (beta ARK) phosphorylates its membrane-associated
receptor substrates, such as the beta-adrenergic receptor, triggering events leading
to receptor desensitization. beta ARK activity is ...
Myocardial expression of a constitutively active alpha 1B-adrenergic receptor in transgenic mice induces cardiac hypertrophy.
(Proc Natl Acad Sci U S A, 1994-10-11)
Transgenic mice were generated by using the alpha-myosin heavy chain promoter coupled
to the coding sequence of a constitutively active mutant alpha 1B-adrenergic receptor
(AR). These transgenic animals demonstrated ...
An approach to the study of G-protein-coupled receptor kinases: an in vitro-purified membrane assay reveals differential receptor specificity and regulation by G beta gamma subunits.
(Proc Natl Acad Sci U S A, 1994-04-26)
Phosphorylation of GTP-binding-regulatory (G)-protein-coupled receptors by specific
G-protein-coupled receptor kinases (GRKs) is a major mechanism responsible for agonist-mediated
desensitization of signal transduction processes. ...
