Swiss-Prot Acc.P15144.Aminopeptidase N (APN, CD13) is a widely expressed, membrane-bound proteolytic enzyme that breaks down peptides during digestion, cleaves cell surface antigens during antigen presentation, and acts as a receptor for human viruses, including several coronaviruses.Plays a role in the final digestion of peptides generated from hydrolysis of proteins by gastric and pancreatic proteases.
