It is generally believed that the signal transduction of AT1 angiotensin receptor (AT1R), the major receptor of angiotensin II, requires ligand binding and subsequent adoption of its active conformation. Activated AT1R induces a plethora of signaling pathways, in contrast to inactive AT1R, which was thought to be silent in terms of signaling. We hypothesized that unliganded, but phosphorylated AT1R may recruit β-arrestins, the key proteins of receptor desensitization, int...
