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

G Protein-Coupled Receptors in Taste Physiology and Pharmacology
Heterotrimeric G protein-coupled receptors (GPCRs) comprise the largest receptor family in mammals and are responsible for the regulation of most physiological functions.

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 ...

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.

The yeast Saccharomyces cerevisiae is powerful for studying human G protein-coupled receptors as they can be coupled to its mating pathway. Here the authors engineer baker’s yeast to produce human sterols and show that vertebrate G protein coupled ...

Lysophosphatidic Acid Signaling in Cancer Cells: What Makes LPA So Special?
Lysophosphatidic acid (LPA) refers to a family of simple phospholipids that act as ligands for G protein-coupled receptors. While LPA exerts effects throughout the body in normal physiological circumstances, its pathological role in cancer is of great ...

GPCRs in Intracellular Compartments: New Targets for Drug Discovery
The architecture of eukaryotic cells is defined by extensive membrane-delimited compartments, which entails separate metabolic processes that would otherwise interfere with each other, leading to functional differences between cells.

G Protein-Coupled Receptors in Macrophages
ABSTRACTAs the largest receptor gene family in the human genome, with >800 members, the signal-transducing G protein-coupled receptors (GPCRs) play critical roles in nearly all conceivable physiological processes, ranging from the sensing of photons and odorants to metabolic homeostasis and migration of leukocytes.

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.

Interaction of Prokineticin Receptors with Accessory Proteins
G protein-coupled receptors (GPCRs) are transmembrane proteins that mediate the intracellular pathway of signals not only through heterotrimeric GTP-binding proteins (G proteins) but also through their associations with a variety of additional partner ...
