Human Aminopeptidase N/CD13 APC-conjugated Antibody

The human ANPEP gene encodes Aminopeptidase N (APN), which is also known as Microsomal Aminopeptidase, Alanyl Aminopeptidase, Aminopeptidase M, CD13, or Membrane Protein p161 (1-3). The deduced amino acid sequence of human APN consists of a short cytoplasmic tail (residues 2 to 8), a transmembrane region (residue 9 to 32), a Ser/Thr rich region and a zinc metalloprotease domain (residues 69 to 966). The amino acid sequence of human APN is 78% and 77% identical to that of rat and mouse, respectively. Widely expressed in many cells, tissues and species, APN cleaves the N-terminal amino acids from bioactive peptides, leading to their inactivation or degradation. The roles of APN in many fields, such as neuroscience, hematopoeitic cells, immune system, angiogenesis, cancer and viral infection, have been reviewed (3).
