Background

ENPEP, or glutamyl aminopeptidase, is a type II integral membrane protein with an extracellular zinc-binding domain. ENPEP plays a significant role in the renin-angiotensin system (RAS) by participating in the catabolic pathway, forming angiotensin III from angiotensin II through the hydrolysis of the N-terminal aspartate (or glutamate), thereby regulating blood pressure and blood vessel formation. ENPEP is widely expressed in a subset of vascular smooth muscle cells, likely pericytes, in systemic vasculature, the heart, and the brain. It is expressed at high levels in the epithelial cells of the kidney glomerulus and proximal tubule cells, where it contributes to the regulation of blood pressure and may contribute to the risk of atrial fibrillation, angiogenesis, hypertension, and tumorigenesis.
