Abstract

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 acetyla- tion levels have been associated with the pathophysiology of a number of diseases, including various forms of neurodegenerative conditions, cancer, and even cystic fibrosis. In this review, we will highlight the biological and clinical significance of microtubule acetylation and the potential of targeting this pathway for therapeutics.
