Microtubules are regulated by microtubule-associated proteins. However, little is known about the structure of microtubule-associated proteins in complex with microtubules. Herein we show that the microtubule-associated protein Tau, which is intrinsically disordered in solution, locally folds into a stable structure upon binding to microtubules. While Tau is highly flexible in solution and adopts a β-sheet structure in amyloid fibrils, in complex with microtubules the conserved hexapeptides at the beginning of the Tau repeats two and three convert into a hairpin conformation. Thus, binding to microtubules stabilizes a unique conformation in Tau.
