catestatin
Catestatin is a protein that plays a role in the regulation of blood pressure. It is derived from a larger precursor protein called chromogranin A. Catestatin is found in various tissues, including the adrenal medulla and neurons. Its primary function is to inhibit the renin-angiotensin-aldosterone system (RAAS), a key hormonal pathway involved in maintaining blood pressure homeostasis.
When catestatin inhibits the RAAS, it leads to a reduction in angiotensin II levels, which in turn
The precise mechanisms by which catestatin exerts its effects are still being investigated. It is known to
