New hypotheses for the GPCR 3D arrangement based on a molecular model of the human sweet-taste receptor

European Journal of Medicinal Chemistry

Abstract

A molecular model of the human sweet-taste receptor has been inferred from superpositions of 3D maps of sweetener interaction sites (themselves previously deduced from extensive structure-activity relationship studies on highly potent sweeteners) onto three well-known G protein-coupled receptors (GPCRs)-rhodopsin, beta(2)- and alpha(2A)-adrenergic receptors-assumed to be linked by common evolutionary origins. The model gives new answers to old questions on the GPCR 3D structure, such as on the orientation and arrangement of the binding helices, their interaxial distances, radial orientations and relative heights. The model should be useful as a new approach to the rational design of drugs.

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.
