Coupling mode of receptors and G proteins
Naunyn-Schmiedeberg's Archives of Pharmacology, 2008Signaling via G-protein-coupled receptors (GPCRs) is crucial to many physiological and pathophysiological processes in multicellular organisms, and GPCRs themselves are targets for important drugs. Classical cell supplementation experiments suggest a collision coupling model, in which receptors and G proteins diffuse randomly within the cell membrane ...

Palmitoylation and G-protein coupled receptors
2022More and more it is being appreciated that not all GPCRs are the same, sub-populations of GPCRs exist within a cell and function differently than others. The question is, how does one regulate a given sub-population? One way is through the addition of post-translational modifications to G-protein coupled receptors (GPCR).

G‐protein‐coupled receptors: an update
Acta Physiologica, 2007Abstract The receptors that couple to G proteins (GPCR) and which span the cell membranes seven times (7‐TM receptors) were the focus of a symposium in Stockholm 2006. The ensemble of GPCR has now been mapped in several animal species. They remain a major focus of interest in drug development, and their diverse physiological and pathophysiological ...

Efficacy at g-protein-coupled receptors
Nature Reviews Drug Discovery, 2002At present, the drug-discovery process centres on ligands that either block or produce physiological responses. However, there are therapeutic uses for ligands that do neither of these things, but which still affect receptors in other ways. This review discusses the intimate relationship between the affinity of a ligand for its receptor, and the ...

G-protein-coupled receptors and cancer
Nature Reviews Cancer, 2007G-protein-coupled receptors (GPCRs), the largest family of cell-surface molecules involved in signal transmission, have recently emerged as crucial players in tumour growth and metastasis. Malignant cells often hijack the normal physiological functions of GPCRs to survive, proliferate autonomously, evade the immune system, increase their blood supply ...

Receptor-effector coupling by G proteins
Biochimica et Biophysica Acta (BBA) - Reviews on Biomembranes, 1990The primary structure of G proteins as deduced from purified proteins and cloned subunits is presented. When known, their functions are discussed, as are recent data on direct regulation of ionic channels by G proteins. Experiments on expression of alpha subunits, either in bacteria or by in vitro translation of mRNA synthesized from cDNA are presented

G‐Protein–Coupled Receptor Deorphanizations
2005G 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.

G protein-coupled receptors in rheumatology
Nature Reviews Rheumatology, 2014G protein-coupled receptors (GPCRs) are transmembrane receptor proteins that allow the transfer of signals across the cell membrane. In addition to their physiological role, GPCRs are involved in many pathophysiological processes including pathways relevant in rheumatoid arthritis (RA), osteoarthritis (OA) and psoriatic arthritis.

G-Protein-Coupled Receptor Microarrays
ChemBioChem, 2002Membrane-bound proteins represent the single most important class of drug targets. Arraying these proteins is difficult because they typically need to be embedded in membranes to maintain their correctly folded conformations. We describe here the fabrication of microarrays consisting of G-protein-coupled receptors (GPCRs)--the single largest family of ...

G-protein coupled receptors in bone
Frontiers in Bioscience, 1998The skeleton is a dynamic structure that undergoes continuous remodeling, a prerequisite to meeting the constant loading demands placed upon it. This process is controlled by a multitude of systemic and local factors which interact with receptors presented on the surface of both osteoblasts and osteoclasts; the osteogenic and osteolytic cells of bone ...
