Recombinant human cytosolic carboxypeptidase 6 (AGBL4) is a metalloprotease belonging to the ATP/GTP-binding protein-like (AGBL) subfamily of carboxypeptidases. It is primarily involved in the post-translational processing of tubulin and other proteins by selectively cleaving C-terminal glutamates, a process critical for regulating protein function and stability. AGBL4. also known as CCP6. plays a key role in maintaining microtubule dynamics through its enzymatic activity in detyrosination cycles, which influence cellular processes like mitosis, intracellular transport, and neuronal development. Structurally, it contains a conserved carboxypeptidase domain and putative catalytic zinc-binding motifs. Dysregulation of AGBL4 has been associated with neurodevelopmental disorders, male infertility, and cancer progression. Studies highlight its tissue-specific expression patterns, particularly in the brain and testis, suggesting specialized roles in neural circuitry and spermatogenesis. Recombinant forms of AGBL4 enable biochemical characterization of its enzymatic mechanisms and substrate specificity, aiding research into microtubule-related pathologies and therapeutic targeting. Recent work also explores its interaction with tubulin isotypes and potential regulatory networks involving post-translational modifications, underscoring its broader implications in cellular homeostasis and disease.
