Microtubule acetylation is a key posttranslational modification that enhances organelle transport, drives cell signaling, and regulates cell cycle regulation. The optimal level of microtubule acetylation is regulated by the acetyltransferase alpha-tubulin-N-acetyltransferase 1and two deacetylases, histone deacetylase 6 and sirtuin-2. Alterations in microtubule acetylation levels have been associated with the pathophysiology of a number of diseases, including various forms of neurodegenerative
