The Neuronal Microtubule‐Associated Protein Tau Is a Substrate for Caspase‐3 and an Effector of Apoptosis
Abstract
We have identified a class of tau fragments inducing apoptosis in different cellular contexts, including a human teratocarcinoma‐derived cell line (NT2 cells) representing committed human neuronal precursors. We have found a transition point inside the tau molecule beyond which the fragments lose their ability to induce apoptosis. This transition point is located around one of the putative caspase‐3 cleavage sites. This is the only site that can be effectively used by caspase‐3 in vitro, releasing the C‐terminal 19 amino acids of tau. These results establish tau as a substrate for an apoptotic protease that turns tau itself into an effector of apoptosis. Accordingly, tau may be involved in a self‐propagating process like what has been predicted for the pathogenesis of different neurodegenerative disorders.

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.
