Abstract

Histone deacetylase 6 (HDAC6), a unique cytoplasmic deacetylase, likely plays a role in neurodegeneration by coordinating cell responses to abnormal protein aggregation. Here, we provide in vitro and in vivo evidence that HDAC6 interacts with tau, a microtubule‐associated protein that forms neurofibrillary tangles in Alzheimer’s disease. This interaction is mediated by the microtubule‐binding domain on tau and the Ser/Glu tetradecapeptide domain on HDAC6. Treatment with tubacin, a selective inhibitor of tubulin deacetylation activity of HDAC6, did not disrupt HDAC6–tau interaction. Nonetheless tubacin treatment attenuated site‐specific tau phosphorylation, as did shRNA‐mediated knockdown of HDAC6. Proteasome inhibition potentiated HDAC6–tau interactions and facilitated the concentration and co‐localization of HDAC6 and tau in a perinuclear aggresome‐like compartment, independent of HDAC6 tubulin deacetylase activity. Furthermore, we observed that in Alzheimer’s disease brains the protein level of HDAC6 was significantly increased. These findings establish HDAC6 as a tau‐interacting protein and as a potential modulator of tau phosphorylation and accumulation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
