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 ...
Desensitization, internalization, and signaling functions of beta-arrestins demonstrated by RNA interference.
(Proc Natl Acad Sci U S A, 2003-02-18)
Beta-arrestins bind to activated G protein-coupled receptor kinase-phosphorylated
receptors, which leads to their desensitization with respect to G proteins, internalization
via clathrin-coated pits, and signaling via a ...
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. ...
