Carboxypeptidase A4 is an enzyme that in humans is encoded by the CPA4 gene.This gene is a member of the carboxypeptidase A/B subfamily and it is located in a cluster with three other family members on chromosome 7. Carboxypeptidases are zinc-containing exopeptidases that catalyze the release of carboxy-terminal amino acids and are synthesized as zymogens that are activated by proteolytic cleavage. This gene could be involved in the histone hyperacetylation pathway.
