Journal ArticleDOI

Agonists induce conformational changes in transmembrane domains III and VI of the β2 adrenoceptor

TL;DR: Findings suggest that IANBD bound to 125Cys and 285Cys are exposed to a more polar environment upon agonist binding, and indicate that movements of transmembrane segments III and VI are involved in activation of G protein‐coupled receptors.
Journal ArticleDOI

Functionally Different Agonists Induce Distinct Conformations in the G Protein Coupling Domain of the β2Adrenergic Receptor

TL;DR: Monitoring ligand-induced conformational changes in the G protein-coupling domain of the β2 adrenergic receptor provides new insight into the structural consequence of antagonist binding and the basis of agonism and partial agonism.
Journal ArticleDOI

Agonist-induced conformational changes in the G-protein-coupling domain of the beta 2 adrenergic receptor.

TL;DR: The authors' studies, when compared with studies of activation in rhodopsin, indicate a general mechanism for GPCR activation; however, a notable difference is the relatively slow kinetics of the conformational changes in the β2AR, which may reflect the different energetics of activation by diffusible ligands.
Journal ArticleDOI

Mutation of a Highly Conserved Aspartic Acid in the β2 Adrenergic Receptor: Constitutive Activation, Structural Instability, and Conformational Rearrangement of Transmembrane Segment 6

TL;DR: It is proposed that protonation of the aspartic acid leads to release of constraining intramolecular interactions, resulting in movements of TM 6 and, thus, conversion of the receptor to the active state.
