Aminopeptidase N (ANPEP), partial, human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 34-219aa. Protein Length: Partial. Tag Info: N-terminal 10xHis-GST-tagged and C-terminal Myc-tagged. Target Protein Sequence: SQEKNKNANS SPVASTTPSA SATTNPASAT TLDQSKAWNR YRLPNTLKPD SYRVTLRPYL TPNDRGLYVF KGSSTVRFTC KEATDVIIIH SKKLNYTLSQ GHRVVLRGVG GSQPPDIDKT ELVEPTEYLV VHLKGSLVKD SQYEMDSEFE GELADDLAGF YRSEYMEGNV RKVVATTQMQ AADARK. Purity: Greater than 85% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Broad specificity aminopeptidase which plays a role in the final digestion of peptides generated from hydrolysis of proteins by gastric and pancreatic proteases. Also involved in the processing of various peptides including peptide hormones, such as angiotensin III and IV, neuropeptides, and chemokines. May also be involved the cleavage of peptides bound to major histocompatibility complex class II molecules of antigen presenting cells. May have a role in angiogenesis and promote cholesterol crystallization. May have a role in amino acid transport by acting as binding partner of amino acid transporter SLC6A19 and regulating its activity. (Microbial infection) Acts as a receptor for human coronavirus 229E/HCoV-229E. In case of human coronavirus 229E (HCoV-229E) infection, serves as receptor for HCoV-229E spike glycoprotein (Microbial infection) Mediates as well Human cytomegalovirus (HCMV) infection.
