Aminopeptidase N (UniProt: P15144; also known as EC:126.96.36.199, AP-N, hAPN, Alanyl aminopeptidase, Aminopeptidase M, AP-M, Microsomal aminopeptidase, Myeloid plasma membrane glycoprotein CD13, gp150, CD13) is encoded by the ANPEP (also known as APN, CD13, PEPN) gene (Gene ID: 290) in human. Aminopeptidase N is a single-pass type II membrane protein that is also found as a soluble form in cells. It is widely expressed as a homodimer of 280 kDa on the cell surface in many tissues, including intestinal epithelia and the nervous system. It serves as a broad specificity aminopeptidase that plays a role in the final digestion of peptides generated from hydrolysis of proteins by gastric and pancreatic proteases. It preferentially cleaves N-terminus neutral amino acids, most notably alanine residue. Aminopeptidase N is involved in many physiological processes, including antigen presentation regulation, differentiation, proliferation, apoptosis, cancer metastasis, and angiogenesis. It is also involved in the processing of various peptides including peptide hormones, such as angiotensin III and IV, neuropeptides, and chemokines. Human Aminopeptidase N consists of a short N-terminal cytoplasmic end (aa 2-8), a transmembrane domain (aa 9-32), and a large extracellular portion (aa 33-967), which is composed of a Ser/Thr-rich region (aa 33-68) and the metalloprotease domain (aa 69-967).
