Gain of function mutants: Ion channels and G protein-coupled receptors [PDF]
Many ion channels and receptors display striking phenotypes for gain-of-function mutations but milder phenotypes for null mutations. Gain of molecular function can have several mechanistic bases: selectivity changes, gating changes including constitutive

Signal Transduction of Sphingosine-1-Phosphate G Protein—Coupled Receptors
Sphingosine-1-phosphate (S1P) is a bioactive lipid capable of eliciting dramatic effects in a variety of cell types. Signaling by this molecule is by a family of five G protein—coupled receptors named S1P1–5 that signal through a variety of pathways to ...

A modeling strategy for G-protein coupled receptors
Cell responses can be triggered via G-protein coupled receptors (GPCRs) that interact with small molecules, peptides or proteins and transmit the signal over the membrane via structural changes to activate intracellular pathways.

G Protein-Coupled Receptor Kinases Take Central Stage
The relevance of the family of G protein-coupled receptor kinases (GRKs) is based on its key participation in the regulation and intracellular dynamics of the largest family of membrane receptors, namely G protein-coupled receptors (GPCRs) [...]

Current applications of mini G proteins to study the structure and function of G protein-coupled receptors [PDF]
G protein-coupled receptors (GPCRs) regulate intracellular signalling pathways that contribute to virtually all aspects of cell function. Characterising GPCRs in each of their conformational states is key to understanding their mechanism of action, but ...

G-protein-coupled receptor kinases
Rhodopsin kinase and the beta-adrenergic receptor kinase (beta ARK) catalyse the phosphorylation of the activated forms of the G-protein-coupled receptors, rhodopsin and the beta 2-adrenergic receptor (beta 2AR), respectively. The interaction between receptor and kinase is independent of second messengers and appears to involve a multipoint attachment ...

Lysophospholipid G Protein-coupled Receptors [PDF]
The many biological responses documented for lysophospholipids that include lysophosphatidic acid and sphingosine 1-phosphate can be mechanistically attributed to signaling through specific G protein-coupled receptors. At least nine receptors have now been identified, and the total number is likely to be larger.

The tyrosine phosphatase CD148 is an essential positive regulator of platelet activation and thrombosis [PDF]
Platelets play a fundamental role in hemostasis and thrombosis. They are also involved in pathologic conditions resulting from blocked blood vessels, including myocardial infarction and ischemic stroke.

G Protein–Coupled Receptor Deorphanizations [PDF]
G protein–coupled receptors (GPCRs) are major regulators of intercellular interactions. They initiate these actions by being activated by a wide variety of natural ligands. Historically, ligands were discovered first, but the advent of molecular biology reversed this trend.
