G-Proteins and Endothelial Responses
Blood Vessels, 2008G-proteins are transducing proteins that couple a large number of membrane-bound receptors to a variety of intracellular effector systems. Pertussis toxin ADP-ribosylates certain G-proteins causing inhibition of their function. In porcine coronary arteries, pertussis toxin inhibited the endothelium-dependent relaxations evoked by alpha-2-adrenergic or ...

G Proteins In Signal Transduction
Annual Review of Pharmacology and Toxicology, 1990The last five years have seen major advances in our understanding of the central and generalized role of G-proteins as transducers of receptor signals into effector responses as outlined in Scheme 1. Signal-transducing G pro teins, in contrast to other GTP-binding proteins, are heterotrimers formed of one GTP-binding (and hydrolyzing) a subunit, one ...

Structure of G Protein–Coupled Receptors and G Proteins
Science's STKE, 2005This Teaching Resource provides lecture notes and slides for a class covering the structure and function of G protein–coupled receptors and is part of the course "Cell Signaling Systems: A Course for Graduate Students." The lecture begins with a discussion of the crystal structure of rhodopsin and G protein subunits and then proceeds to describe the ...

Conditional Mutagenesis of G-Protein Coupled Receptors and G-Proteins
2007The G-protein-coupled receptor signaling system, consisting of a huge variety of receptors as well as of many G-proteins and effectors, operates in every cell and is involved in many physiological and pathological processes. The versatility of this system and the involvement of specific components makes G-protein-coupled receptors and their signaling ...
