Carboxypeptidase A6 (CPA6) is a metallocarboxypeptidase enzyme that in humans is encoded by the CPA6 gene.[5] It is highly expressed in the adult mouse olfactory bulb and is broadly expressed in the embryonic brain and other tissues.[6]

The protein encoded by this gene belongs to the family of carboxypeptidases, which catalyze the release of C-terminal amino acid, and have functions ranging from digestion of food to selective biosynthesis of neuroendocrine peptides. Polymorphic variants and a reciprocal translocation t(6;8)(q26;q13) involving this gene, have been associated with Duane retraction syndrome.[5]

CPA6 processes several neuropeptides, including [Met]- and [Leu]-enkephalin, angiotensin I, and neurotensin in vitro.[6] Whereas CPA6 is capable of converting the enkephalins and neurotensin into inactive forms, it can convert the inactive angiotensin I into the active angiotensin II.[6] CPA6 may have additional roles in processing peptides and proteins in vivo, but the nature of these substrates and the effects of these cleavages are currently unknown.
