The human AT1 receptor consists of a 376 amino acid string <ref> [http://www.ebi.ac.uk/thornton-srv/databases/cgi-bin/pdbsum/GetPage.pl?pdbcode=4zud&template=main.html Protein Database (PDBsum): 4zud.

The protein is composed of <scene name='82/829348/Helix_a/1'>18 α helixes</scene> and a <scene name='82/829348/B_sheet/1'>single β sheet</scene> composed of 3 β strands. Moreover, 7 α helixes are made of a majority of hydrophobic amino acids. These helixes are long enough to cross the membrane and create a <scene name='82/829348/Transmambrane_protein/1'>hydrophobic domain</scene> which is situated into the membrane. The human angiotensin receptor is therefore an α helical trans-membrane protein. | ||
Since the angiotensin receptor belongs to the GPCRs family, those 7 α helixes contain 3 extracellular and 3 intracellular loops. The N terminus corresponds to the extracellular domain. The C terminal domain is located intracellularly. | Since the angiotensin receptor belongs to the GPCRs family, those 7 α helixes contain 3 extracellular and 3 intracellular loops.
