Abstract: | (CIT): G protein-coupled receptors (GPCR) mediate numerous physiological responses. These responses are regulated by kinases (GRKs) followed by binding of the phosphorylated receptors to the scaffold protein, Betta-arrestin. This interaction not only dampens G protein-dependent signaling but also targets receptors for internalization and initiates additional signaling events through the ability of Betta-arrestin to scaffold signaling complexes. In the brain the dopaminergic system is presumably implicated in the control of locomotion, cognition and affect. In mice, activation of D2-like receptors modulates not only the cAMP-dependent signaling pathway but also engages an Akt/PP2A/GSK3 signaling pathway that is mediated by the ability of Betta-arrestin to scaffold these proteins. The NIH Director's Wednesday Afternoon Lecture Series includes weekly scientific talks by some of the top researchers in the biomedical sciences worldwide. |
