Structural biology of G protein-coupled receptors.
More than 60% of the current drugs are based on G protein-coupled receptors. Paradoxically, high-resolution structures are not available to facilitate rational drug design. Difficulties in expression, purification, and crystallization of these transmembrane receptors are the reasons for the low success rate. Recent individual and network-based technology development has significantly improved o...
متن کاملStructural Studies of G Protein-Coupled Receptors
G protein-coupled receptors (GPCRs) constitute the largest and the most physiologically important membrane protein family that recognizes a variety of environmental stimuli, and are drug targets in the treatment of numerous diseases. Recent progress on GPCR structural studies shed light on molecular mechanisms of GPCR ligand recognition, activation and allosteric modulation, as well as structur...
متن کاملStructural organization of G-protein-coupled receptors
Atomic-resolution structures of the transmembrane 7-alpha-helical domains of 26 G-protein-coupled receptors (GPCRs) (including opsins, cationic amine, melatonin, purine, chemokine, opioid, and glycoprotein hormone receptors and two related proteins, retinochrome and Duffy erythrocyte antigen) were calculated by distance geometry using interhelical hydrogen bonds formed by various proteins from ...
متن کاملLarge-scale production and protein engineering of G protein-coupled receptors for structural studies
Structural studies of G protein-coupled receptors (GPCRs) gave insights into molecular mechanisms of their action and contributed significantly to molecular pharmacology. This is primarily due to technical advances in protein engineering, production and crystallization of these important receptor targets. On the other hand, NMR spectroscopy of GPCRs, which can provide information about their dy...
متن کاملG Protein-coupled receptors
G protein-coupled receptors and heterotrimeric G proteins can diffuse laterally in the plasma membrane such that one receptor can catalyze the activation (GDP/GTP exchange) of multiple G proteins. In some cases, these processes are fast enough to support molecular signal amplification, where a single receptor maintains the activation of multiple G proteins at steady-state. Amplification in cell...
