Cytosolic carboxypeptidase 3 (Agbl3)

Metallocarboxypeptidase which mediates both deglutamylation and deaspartylation of target proteins. Catalyzes the deglutamylation of polyglutamate side chains generated by post-translational polyglutamylation in proteins such as tubulins.

Also removes gene-encoded polyglutamates or polyaspartates in the carboxy-terminus of target proteins like MYLK. Doesn't show detyrosinase or deglycylase activities from the carboxy- terminus of tubulin.
