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 ...
