Our findings indicate that several acetylation sites in tau are responsive to HDAC6 and that acetylation on Lys-321 (within a KCGS motif) is both essential for acetylation-mediated inhibition of tau aggregation in vitro and a molecular tactic for preventing phosphorylation on the downstream Ser-324 residue. Tau phosphorylation of Ser-324 (pSer-324) has not previously been evaluated in the context of tauopathy, and here we observed increased deposition of pSer-324-positive tau both in mouse models of tauopathy and in patients with Alzheimer's disease. These findings uncover a novel acetylation-phosphorylation switch at Lys-321/Ser-324 that coordinately regulates tau polymerization and function.
