G Protein–Coupled Receptor Rhodopsin [PDF]
The rhodopsin crystal structure provides a structural basis for understanding the function of this and other G protein–coupled receptors (GPCRs). The major structural motifs observed for rhodopsin are expected to carry over to other GPCRs, and the mechanism of transformation of the receptor from inactive to active forms is thus likely conserved ...

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.

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 ...

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 melanocortin receptors and their accessory proteins. [PDF]
The five melanocortin receptors (MCRs) named MC1R-MC5R have diverse physiological roles encompassing pigmentation, steroidogenesis, energy homeostasis and feeding behavior as well as exocrine function.

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 ...

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.

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 ...

Positive allosteric modulators of the a-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor [PDF]
L-glutamate is the major excitatory neurotransmitter in the mammalian central nervous system (CNS) and plays a fundamental role in the control of motor function, cognition and mood.
