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 ...
Independent beta-arrestin 2 and G protein-mediated pathways for angiotensin II activation of extracellular signal-regulated kinases 1 and 2.
(Proc Natl Acad Sci U S A, 2003-09-16)
Stimulation of a mutant angiotensin type 1A receptor (DRY/AAY) with angiotensin II (Ang II) or of a wild-type receptor with an Ang II analog ([sarcosine1,Ile4,Ile8]Ang II) fails to activate classical heterotrimeric G protein ...
Smoothened signal transduction is promoted by G protein-coupled receptor kinase 2.
(Mol Cell Biol, 2006-10)
Deregulation of the Sonic hedgehog pathway has been implicated in an increasing number of human cancers. In this pathway, the seven-transmembrane (7TM) signaling protein Smoothened regulates cellular proliferation ...
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 ...
