Pig Glutamyl Aminopeptidase (Aminopeptidase A) (ENPEP) ELISA Kit

Background

Glutamyl aminopeptidase (ENPEP), also known as aminopeptidase A (APA) or CD249, is a zinc-dependent metallopeptidase involved in the regulation of blood pressure, modulation of immune responses, and amino acid metabolism. ENPEP is encoded by the ENPEP gene and functions primarily by cleaving N-terminal glutamyl and aspartyl residues from peptide substrates. As a member of the M1 family of aminopeptidases, ENPEP is a single-pass membrane protein found predominantly in kidney, intestine, and endothelial tissues. It also exists in various immune cells and is a critical regulator in the renin-angiotensin system (RAS), where it facilitates the conversion of angiotensin II to angiotensin III, thereby influencing blood pressure and fluid balance. ENPEP’s role in the RAS system is pivotal because of its impact on hypertension, cardiovascular diseases, and kidney functions. Additionally, ENPEP has implications in immune response regulation, making it a potential target in the treatment of inflammatory and autoimmune diseases. Research into ENPEP function and expression patterns is essential to better understand how this enzyme could be modulated for therapeutic benefits in hypertension, metabolic disorders, and immune system-related diseases.
