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 ...
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 ...
Platelet-derived growth factor receptor association with Na(+)/H(+) exchanger regulatory factor potentiates receptor activity.
(Mol Cell Biol, 2000-11)
Platelet-derived growth factor (PDGF) is a potent mitogen for many cell types. The
PDGF receptor (PDGFR) is a receptor tyrosine kinase that mediates the mitogenic effects
of PDGF by binding to and/or phosphorylating a variety ...
The role of β-arrestins in the termination and transduction of G-protein-coupled receptor signals
(Journal of Cell Science, 2002-02-01)
β-arrestins are versatile adapter proteins that form complexes with most G-protein-coupled
receptors (GPCRs) following agonist binding and phosphorylation of receptors by G-protein-coupled
receptor kinases (GRKs). They play ...
