Tau acetylation at K280 regulates tau phosphorylation.

Here we identified tau phosphorylation profile in the context of p300-induced acetylation and K280A-mutant tau, demonstrating that tau acetylation affects phosphorylation differently by residues and that acetylation at K280 is a determinant of phosphorylation at some residues in the context of pathologic acetyltransferase activity. Yet, our results suggest there is a complex interplay yet to be explored between tau acetylation with tau phosphorylation.
