clarify the molecular mechanisms governing ligand efficacy and potency at the β2 adrenergic receptor (β2AR Through an in-depth mutational analysis of β2AR, the researchers identified specific residues that influence By identifying key β2AR residues that influence efficacy and potency, pharmaceutical researchers can GPCRs, including β2AR, play key roles in various conditions, such as asthma, cardiovascular diseases, For instance, a patient with a specific variant of the β2AR gene that reduces potency might require a

Agonist activation of the β2-adrenoceptor (β2AR) causes its S-nitrosylation that is required for the Eliminating β2AR S-nitrosylation by mutation of C265 augments β2AR protein kinase A signaling, enables β2AR nitric oxide (NO) signaling, renders mice resistant to bronchoconstriction, and protects mice from

in 2017 showed that Gs played a pivotal role in calcium signalling at the β2-adrenergic receptors (β2AR Overall, the increased calcium signalling was attributed to the release of ATP via β2AR-Gs mediated activation However, IP1 signalling through the non-cognate Gq was not important for the increased β2AR-Gs-mediated

We computationally docked ~2700 known β2AR ligands to multiple β2AR structures, generating ca 75 000

variability analysis to monitor the transitions of the Gs protein in complex with the β2-adrenergic receptor (β2AR reveal a dynamic of conformational changes initiated by the binding of an agonist isoproterenol to β2AR

As signaling via the GPCRs, β2-adrenergic receptor (β2AR), and metabotropic glutamate receptor 2 (mGluR2 Here, we report that β-arrestins are not only essential for β2AR and mGluR2-mediated increase in pathogenic

research are: Nb80: This nanobody stabilized an active-state conformation of the β2 adrenergic receptor (β2AR It has slower dissociation kinetics at the β2AR and was used to capture the structure of β2AR bound to Nb35: This nanobody selectively binds to the β2AR·Gs complex and prevents the dissociation of the nucleotide-free Nb37: Similar to Nb35, this nanobody selectively binds to the β2AR·Gs complex and helps reveal the conformational

conformational changes induced by the binding of a nanobody (Nb80) on the active-like β2 adrenergic receptor (β2AR Dimensionality reduction analysis shows that Nb80 stabilizes structural features of the β2AR with an

Genomics, in turn, played a crucial role in the discovery and sequencing of the beta-adrenergic receptor (βAR For example over 160 SNPs have been reported for the β2AR gene, with some of these SNPs having clinical

allosteric antagonists are under investigation for several GPCRs, including CCR2, CCR7, CCR9, CXCR2, and β2AR

The β 2-adrenergic receptor ( β 2AR) is a prototypical and extensively studied GPCR that can provide biosensors, second messenger assays, and biochemical techniques, we characterize the properties of β 2AR-F193A This single point mutation in extracellular loop 2 of the β 2AR is sufficient to intrinsically bias the β 2AR away from β -arrestin interaction and demonstrates altered regulatory outcomes downstream of this
