When the angiotensin II binds to the angiotensin receptor in the ligand binding pocket, the conformation of the trans-membrane domain changes to create a cytosolic cleft for the binding and activation of G proteins. In this cleft, several conserved residues can be found, which form functional motifs present in all [[GPCRs]] <ref> PMID:30608150 </ref>. | When the angiotensin II binds to the angiotensin receptor in the ligand binding pocket, the conformation of the trans-membrane domain changes to create a cytosolic cleft for the binding and activation of G proteins.

AngII mediates AT1 receptor activation via stacking interactions between Phe8(AngII)/<scene name='82/829348/His_256/2'>His256</scene>(AT1 receptor) and Tyr4(AngII)/<scene name='82/829348/Asn_111/1'>Asn111</scene>(AT1 receptor). This phenomenon results in a conformational change in transmembrane (TM)3-TM6 helixes and in interaction between TM2 and TM7. | AngII mediates AT1 receptor activation via stacking interactions between Phe8(AngII)/<scene name='82/829348/His_256/2'>His256</scene>(AT1 receptor) and Tyr4(AngII)/<scene name='82/829348/Asn_111/1'>Asn111</scene>(AT1 receptor).
