Extended Data Fig. 4: Atomic resolution model of A1R transmembrane domains, the Gα protein α5-helix, ADO, and representative regions of Gβ and Gγ in the cryo-EM density map.
From: Structure of the adenosine-bound human adenosine A1 receptor–Gi complex
a, The molecular model is shown in stick representation and the cryo-EM map in mesh contoured at 0.06. b–d, A1R residues (b, c,) and Gαi2 α5-helix residues (d). The molecular model is shown in stick representation and the cryo-EM map in mesh contoured at 0.06.
