Background: Tubulin acetylation is a hallmark of microtubule stabilization, which may modulate the binding of microtubule-associated proteins. Results: Microtubules are hyperacetylated because of stress-induced cellular signaling upstream of the tubulin acetyltransferase MEC-17/αTAT1. Conclusion: MEC-17/αTAT1 is regulated by p300, reactive oxygen species, and AMP-activated protein kinase. Significance: Microtubule hyperacetylation is important for cell adaptation to stress through autophagy induction and for cell survival.
