ENPEP / aminopeptidase A Protein Description

ENPEP, also known as aminopeptidase A, is a member of the peptidase M1 family. Peptidase M1 family proteins locate in 6 components and are expressed in 26 plant structures. They function in metallopeptidase activity and zinc ion binding. They are also involved in response to cadmium ion and proteolysis. ENPEP is expressed by epithelial cells of the proximal tubule cells and the glomerulus of the nephron. It also can be detected in a variety of other tissues. ENPEP is a zinc-dependent membrane-bound aminopeptidase that catalyzes the cleavage of glutamatic and aspartatic amino acid residues from the N-terminus of polypeptides. It degrades vasoconstricting angiotensin II into angiotensin III and therefore helps to regulate blood pressure. ENPEP probably plays a role in regulating growth and differentiation of early B-lineage cells. It also may play a role in the catabolic pathway of the renin-angiotensin system.
