The identification of ligands at orphan G-protein coupled receptors.
The completion of the human genome sequencing project has identified approximately 720 genes that belong to the G-protein coupled receptor (GPCR) superfamily. Approximately half of these genes are thought to encode sensory receptors. Of the remaining 360 receptors, the natural ligand has been identified for approximately 210 receptors, leaving 150 so-called orphan GPCRs with no known ligand or ...
متن کاملVirtual Screen for Ligands of Orphan G Protein-Coupled Receptors
This paper describes a virtual screening methodology that generates a ranked list of high-binding small molecule ligands for orphan G protein-coupled receptors (oGPCRs), circumventing the requirement for receptor three-dimensional structure determination. Features representing the receptor are based only on physicochemical properties of primary amino acid sequence, and ligand features use the t...
متن کاملPortraying G Protein-Coupled Receptors with Fluorescent Ligands
The thermodynamics of ligand-receptor interactions at the surface of living cells represents a fundamental aspect of G protein-coupled receptor (GPCR) biology; thus, its detailed elucidation constitutes a challenge for modern pharmacology. Interestingly, fluorescent ligands have been developed for a variety of GPCRs in order to monitor ligand-receptor binding in living cells. Accordingly, new m...
متن کاملStrategies to identify ligands for orphan G-protein-coupled receptors.
G-protein-coupled receptors are the most tractable class of protein targets for small molecule drug design. Sequencing of the human genome allied to bio-informatic analysis has identified a large number of putative receptors for which the natural ligands remain undefined. A range of currently employed and developing strategies to identify ligands that interact with these orphan receptors and to...
متن کاملActivation of G-protein-coupled receptors: a common molecular mechanism.
G-protein-coupled receptors (GPCRs) are a large family of proteins that contain a seven transmembrane helical structural motif. They mediate responses to several ligands by binding and activating intracellular heterotrimeric G proteins. Since the cloning of the first GPCR, insights gained from structure-function studies, genetics and drug development have contributed to uncovering a common mech...
