Regulation of G protein-coupled receptor signaling by scaffold proteins.
(Circ Res, 2002-10-18)
The actions of many hormones and neurotransmitters are mediated through stimulation
of G protein-coupled receptors. A primary mechanism by which these receptors exert
effects inside the cell is by association with heterotrimeric ...
Differential mechanisms of morphine antinociceptive tolerance revealed in (beta)arrestin-2 knock-out mice.
(J Neurosci, 2002-12-01)
Morphine induces antinociception by activating mu opioid receptors (muORs) in spinal
and supraspinal regions of the CNS. (Beta)arrestin-2 (beta)arr2), a G-protein-coupled
receptor-regulating protein, regulates the muOR in ...
Defective lymphocyte chemotaxis in beta-arrestin2- and GRK6-deficient mice.
(Proc Natl Acad Sci U S A, 2002-05-28)
Lymphocyte chemotaxis is a complex process by which cells move within tissues and
across barriers such as vascular endothelium and is usually stimulated by chemokines
such as stromal cell-derived factor-1 (CXCL12) acting ...
