Crystal structure of the human β2 adrenergic G-protein-coupled receptor

Abstract: Structural analysis of G-protein-coupled receptors (GPCRs) for hormones and neurotransmitters has been hindered by their low natural abundance, inherent structural flexibility, and instability in detergent solutions. Here we report a structure of the human beta2 adrenoceptor (beta2AR), which was crystallized in a lipid environment when bound to an inverse agonist and in complex with a Fab that binds to the third intracellular loop. Diffraction data were obtained by high-brilliance microcrystallography and the … Show more

“…3d). The HETx motif is highly conserved in family B members and is equivalent to the conserved E/DRY motif in family A GPCRs, whose interactions have also been shown to stabilize the inactive state 39 . Accordingly, mutation of HETx motif residues results in constitutive activation of many family B GPCRs 40, 41 .…”

“…In this context, experimentally validated GPCR homology models have proven to be valuable tools for lead identification, and the scientific literature flourished with successful rational drug design and virtual screening examples [7][8][9][10][11]. In 2007 Kobilka and coworkers unveiled the 3D crystal structure of the human β 2 -adrenergic receptor (β 2 -AR), finally providing the long awaited proof that the structure of GPCRs generally resembles that of rhodopsin [12][13][14][15]. Comparison between rhodopsin-based models of the β 2 -AR in complex with the inverse agonist carazolol and the corresponding crystal structure supports and encourages the applicability of GPCR homology modeling and molecular docking to computer-aided drug discovery, at least for qualitative purposes [16].…”

“…Depuis la caractérisation des premiers gènes codant pour les RCPG à la fin des années 1980, les techniques de clonage recombinant permettent d'introduire facilement des séquences épitopes à l'extrémité amino-ou carboxy-terminale de chaque récepteur, contre lesquelles des anticorps spécifiques sont développés. L'épitope Flag, reconnu par les anticorps M1 et M2, a été positionné par exemple à l'extrémité amino-terminale du 2AR et permet une purification efficace du récepteur [7]. L'épitope 6×His (constitué de 6 histidines successives) est souvent introduit à l'extrémité carboxy-terminale des RCPG [22].…”
