Angiotensin II type 1 receptor, or AT1 receptor is the best characterized angiotensin receptor. It has vasopressor effects and regulates aldosterone secretion. It is an important effector controlling blood pressure and volume in the cardiovascular system. Angiotensin II receptor antagonists are drugs indicated for hypertension, diabetic nephropathy and congestive heart failure. Angiotensin II receptor type 1 has been shown to interact with Zinc finger and BTB domain-containing protein 16. The protein's mRNA has been reported to interact with Mir-132 microRNA as part of an RNA silencing mechanism that reduces receptor expression.
