abstract = {Pathogenic aggregation of the protein tau is a hallmark of
Alzheimer's disease and several other tauopathies.
Tauopathies are characterized by the deposition of specific
tau isoforms as disease-related tau filament structures. The
molecular processes that determine isoform-specific
deposition of tau are however enigmatic. Here we show that
acetylation of tau discriminates its isoform-specific
aggregation. We reveal that acetylation strongly attenuates
aggregation of four-repeat tau protein, but promotes amyloid
formation of three-repeat tau. We further identify
acetylation of lysine 298 as a hot spot for isoform-specific
tau aggregation. Solid-state NMR spectroscopy demonstrates
that amyloid fibrils formed by unmodified and acetylated
three-repeat tau differ in structure indicating that
site-specific acetylation modulates tau structure. The
results implicate acetylation as a critical regulator that
guides the selective aggregation of three-repeat tau and the
development of tau isoform-specific neurodegenerative
diseases.},
