Carboxypeptidase A1 is an enzyme that in humans is encoded by the CPA1 gene.^[3]

Three different forms of human pancreatic procarboxypeptidase A have been isolated. The A1 and A2 forms are monomeric proteins with different biochemical properties. Carboxypeptidase A1 is a monomeric pancreatic exopeptidase. It is involved in zymogen inhibition.^[3]
