CPA4 Human

Source: Sf9, Baculovirus cells.Sterile Filtered colorless solution.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.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.CPA4 is expressed with an 8 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
