General Comments
APN (ANPEP) is a neutral metallo-aminopeptidase that catalyses the removal of neutral and basic amino acids from the N-terminus of protein or peptide substrates. Since dysregulated APN expression has been associated with inflammatory diseases and some types of cancer, pharmacological inhibition of APN may offer effective therapy for these indications.
