Renin (Angiotensinogenase) Renin, also called angiotensinogenase, is an enzyme involved in the reninâangiotensin aldosterone system (RAAS), which regulates the bodyâs water balance and blood pressure level. The system regulates the extracellular volume in the blood plasma, lymph and interstitial fluid, as well as controlling constriction of the arteries and blood vessels.
