MCA2183PE recognises mouse aminopeptidase N (APN), a cell surface protein homologous with human CD13. In the mouse, CD13 is a non-covalently linked homodimer of approximately 150 kDa subunits expressed by a variety of cells including monocytes, macrophages, dendritic cell and veiled cells. Clone R3-63 has been reported to block mouse APN enzyme activity (1). Serotec recommend the use of MCA2183XZ for this purpose.
Purification
Purified IgG prepared by affinity chromatography on Protein G from tissue culture supernatant
CD13 also known as Aminopeptidase N is a zinc dependent exopeptidase which cleaves amino acids from the N termini of target proteins including neuropeptides and cytokines. CD13 is expressed on all cells of the myeloid lineage as well as epithelial cells of the intestine, placenta, liver and kidney. CD13 is upregulated in a number of tumour types including lung, melanoma, thyroid and hepatocarcinoma and has been shown to correlate with poor prognosis. CD13 is a crucial molecule in tumour angiogenesis. CD13 is also the receptor for viruses from the coronavirus family.Synonyms: ANPEP, APN, Alanyl aminopeptidase, Aminopeptidase M, Aminopeptidase N, Microsomal aminopeptidase, Myeloid plasma membrane glycoprotein CD13, PEPN, gp150
