XPNPEP2 Protein, Human, Recombinant (His)
(Synonyms: X-prolyl aminopeptidase (aminopeptidase P) 2, membrane-bound, APP2, AEACEI) Copy Product InfoSynonyms: X-prolyl aminopeptidase (aminopeptidase P) 2, membrane-bound, APP2, AEACEI
Catalog No. TMPY-02120 Copy Product Info
Aminopeptidase P (APP) is a hydrolase specific for N-terminal imido bonds, which are common to several collagen degradation products, neuropeptides, vasoactive peptides, and cytokines. A membrane-bound and soluble form of this enzyme (XPNPEP2) have been identified as products of two separate genes. XPNPEP2, the X-linked gene that encodes membranous aminopeptidase P (APP), has been reported to associate with APP activity. The membrane aminopeptidase P (XPNPEP2) is largely limited in distribution to endothelia and brush border epithelia. APP and XPNPEP2 contain homologous blocks of sequence common to members of the "pita bread-fold" protein family, of which Escherichia coli methionine aminopeptidase is the prototype. The C-2399A variant in XPNPEP2 is associated with reduced APP activity and a higher incidence of AE-ACEi. XPNPEP2 mRNA was detected in fibroblasts that carry the translocation, suggesting that this gene at least partially escapes X inactivation. XPNPEP2 is a candidate gene for premature ovarian failure (POF).

| Species | Human |
| Expression System | HEK293 Cells |
| Tag | C-His |
| Accession Number | O43895 |
| Construction | A DNA sequence encoding the human XPNPEP2 (O43895) (Met 1-Ala 650) without the pro peptide was expressed, with a polyhistidine tag at the C-terminus. Predicted N terminal: His 22 |
| Protein Purity | > 97 % as determined by SDS-PAGE |
| Endotoxin | < 1.0 EU/μg of the protein as determined by the LAL method. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization. |
| Reconstitution | A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information. |
| Stability & Storage | It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
| Shipping | In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice. |
| Synonyms | X-prolyl aminopeptidase (aminopeptidase P) 2, membrane-bound, APP2, AEACEI |
| Research Background |
| Molecular Weight | 72 kDa (predicted); 80 kDa (reducing condition, due to glycosylation) |
| Storage | Lyophilized powder: -20~-80°C for 1 year | Solution: -80°C for 6 months |
