Formulation |
CPA4 protein solution (1mg/ml) contains Phosphate Buffered Saline (pH 7.4) and 10% glycerol. |
Purity |
Greater than 95.0% as determined by SDS-PAGE. |
Description |
CPA4 produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 413 amino acids (17-421a.a.) and having a molecular mass of 46.6kDa (Molecular size on SDS-PAGE will appear at approximately 40-57kDa).CPA4 is expressed with an 8 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques. |
Protein Background |
Carboxypeptidase A4 (CPA4) belongs to the carboxypeptidase A/B subfamily, and it is located in a cluster with 3 other family members on chromosome 7. CPA4 is a secreted, zinc-dependent metallocarboxypeptidase, which removes the C-terminal amino acid from peptides having a free C-terminal carboxyl group. CPA4 is a metalloprotease which may be involved in the histone hyperacetylation pathway. CPA4 are synthesized as zymogens which are activated by proteolytic cleavage. |
Expression host |
Sf9, Baculovirus cells. |
Synonyms |
Carboxypeptidase A4, Carboxypeptidase A3, CPA3, EC 3.4.17.1, EC 3.4.17.-, EC 3.4.17, Carboxypeptidase A4, Carboxypeptidase A3. |
Reagent Appearance |
Sterile Filtered colorless solution. |
Stability |
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles. |
