Single-molecule studies of the conformations of the intact β2 adrenergic receptor were performed in solution. Photon bursts from the fluorescently tagged adrenergic receptor in a micelle were...
Heterozygous α2A-adrenergic receptor mice unveil unique therapeutic benefits of partial agonists
Tan, Christopher M., Wilson, Matthew H., MacMillan, Leigh B., Kobilka, Brian K., Limbird, Lee E.
Genetic manipulation of the α2A-adrenergic receptor (α2A-AR) in mice has revealed the role of this subtype in numerous responses, including agonist-induced hypotension and sedation. Unexpectedly,...

Organization of β-adrenoceptor signaling compartments by sympathetic innervation of cardiac myocytes
Shcherbakova, Olga G., Hurt, Carl M., Xiang, Yang, Dell'Acqua, Mark L., Zhang, Qi, Tsien, Richard W., ...
The sympathetic nervous system regulates cardiac function through the activation of adrenergic receptors (ARs). β1 and β2ARs are the primary sympathetic receptors in the heart and play different...
Dosage-dependent switch from G protein-coupled to G protein-independent signaling by a GPCR
Sun, Yutong, Huang, Jianyun, Xiang, Yang, Bastepe, Murat, Jüppner, Harald, Kobilka, Brian K, ...
G-protein-coupled receptors (GPCRs) mostly signal through heterotrimeric G proteins. Increasing evidence suggests that GPCRs could function in a G-protein-independent manner. Here, we show that at...
Structure-based discovery of β2-adrenergic receptor ligands
Kolb, Peter, Rosenbaum, Daniel M., Irwin, John J., Fung, Juan José, Kobilka, Brian K., Shoichet, Brian K.
Aminergic G protein-coupled receptors (GPCRs) have been a major focus of pharmaceutical research for many years. Due partly to the lack of reliable receptor structures, drug discovery efforts have...
