Background: Carboxypeptidase B1/CPB1

Carboxypeptidase B1, encoded by the CPB1 gene, specifically cleaves the C-terminal Arg and Lys residues with a preference for Arg (1). The deduced amino acid sequence of mouse CPB1 consists of a signal peptide (residues 1 to 15), a pro region (residue 16 to 108), and a mature chain (residues 109 to 415). The purified rmCPB1 corresponds to the pro form, which can be activated by trypsin, the only pancreatic protease capable of generating active enzyme from the zymogen in vitro (1).
