Activation and targeting of extracellular signal-regulated kinases by beta-arrestin scaffolds.
(Proc Natl Acad Sci U S A, 2001-02-27)
Using both confocal immunofluorescence microscopy and biochemical approaches, we have examined the role of beta-arrestins in the activation and targeting of extracellular signal-regulated kinase 2 (ERK2) following stimulation ...
Augmentation of cardiac contractility mediated by the human beta(3)-adrenergic receptor overexpressed in the hearts of transgenic mice.
BACKGROUND: Stimulation of beta(1)- and beta(2)-adrenergic receptors (ARs) in the heart results in positive inotropy. In contrast, it has been reported that the beta(3)AR is also expressed in the human heart and that its ...
Generation of high curvature membranes mediated by direct endophilin bilayer interactions.
(J Cell Biol, 2001-10-15)
Endophilin 1 is a presynaptically enriched protein which binds the GTPase dynamin and the polyphosphoinositide phosphatase synptojanin. Perturbation of endophilin function in cell-free systems and in a living synapse has ...
beta-Arrestin 1 and 2 differentially regulate heptahelical receptor signaling and trafficking.
(Proc Natl Acad Sci U S A, 2001-02-13)
The two widely coexpressed isoforms of beta-arrestin (termed beta arrestin 1 and 2) are highly similar in amino acid sequence. The beta-arrestins bind phosphorylated heptahelical receptors to desensitize and target them ...
beta-Arrestin1 modulates lymphoid enhancer factor transcriptional activity through interaction with phosphorylated dishevelled proteins.
(Proc Natl Acad Sci U S A, 2001-12-18)
One aspect of the function of the beta-arrestins is to serve as scaffold or adapter molecules coupling G-protein coupled receptors (GPCRs) to signal transduction pathways distinct from traditional second messenger pathways. ...
