Renin substrate – Growth Factors and Cytokines

Residues 1-14 of the plasma glycoprotein angiotensinogen (ANG). ANG is a macromolecular precursor of angiotensin I and subsequent angiotensin family members. Angiotensins regulate blood pressure and electrolyte balance. ANG is selectively cleaved by the aspartic protease, renin, to initiate the angiotensin-processing cascade. This region represents the renin cleavage site of ANG, also known as renin substrate.
