Two Angiotensin II Receptors (IMAGE) DOE/SLAC National Accelerator Laboratory Caption Although the two angiotensin II receptors are thought to be very similar, an X-ray study showed clear differences in the pockets where the receptors bind to drug-like compounds. This illustration shows details in the pocket structures of AT2 (left) and AT1 (right).
