Background: Carboxypeptidase A4/CPA4

Carboxypeptidase A4 encoded by the CPA4 gene is a member of the metallocarobxypeptidase family that cleaves the C-terminal amide or ester bond of peptides that have a free C-terminal carboxyl group. The deduced amino acid sequence of mouse CPA4 consists of a signal peptide (residues 1 to 16), a pro region (residue 17 to 113), and a mature chain (residues 114 to 420). The purified recombinant mouse CPA4 corresponds mainly to the pro form, which can be activated and assayed under the conditions described in the Activity Assay Protocol.
