G protein-coupled receptors (GPCRs) constitute the largest single class of receptors and are responsible for mediating much of intracellular mammalian signaling. Indeed, over 40 percent of the pharmacological targets being evaluated by drug companies are related to G protein-coupled receptors. ...
G protein‐coupled receptorgenetic variationoral sensationIn humans, the 25 bitter taste receptors (T2Rs) are activated by hundreds of structurally diverse bitter compounds. However, only 5 antagonists or bitter blockers are known. In this study, using molecular modeling guided site-directed ...
G protein-coupled receptors (GPCRs) are transmembrane proteins that participate in many physiological processes and represent major pharmacological targets. Recent advances in structural biology of GPCRs have enabled the development of drugs based on the receptor structure (structure-based drug design, SB...
However, alterations of these receptors in diseases, causes of these alterations, and their relations with the development of diseases are studied only in few cases. This review considers some mechanisms of regulation of activity and expression of G-protein-coupled receptors (GPCRs) that comprise ...
G protein-coupled receptors and their effectors can now be released directly from a lipid bilayer using infrared irradiation for proteoform-level characterization by native top-down mass spectrometry. This represents a critical development for drug discovery, as the direct role of post-translational modi...
G protein coupled receptors - have membrane-bound protein associated with a trimeric G protein- initiate second messenger systems GPCR mechanism - ligand binding engages G protein- GDP is replaced w/ GTP, the α subunit dissociate from the β & γ subunits- the activated α subunit alters activi...

The past decade has seen tremendous advances in the study of G protein-coupled receptors (GPCRs), including the molecular cloning and identification of more than 100 hundred GPCR genes. But while GPCRs serve as targets for more than 300 medicines in the modern pharmacopoeia, the shrinking pool...
Bitter taste receptors (TAS2Rs) are a subfamily of G-protein coupled receptors (GPCRs). Here, the authors report a cryo-EM structure of the human TAS2R14 in complex with its signaling partner gustducin, and bound to an anti-inflammatory drug flufenamic acid (FFA). ...
More recently, it has become apparent that extracellular calcium (Ca 2+ o) also serves as an extracellular first messenger following the cloning of a Ca 2+ o-sensing receptor (CaR) that belongs to the superfamily of G protein-coupled receptors (GPCR). The CaR probably functions as a dimer...
