Domains of tau Protein and Interactions with Microtubules

Abstract

The role of the neuronal microtubule-associated protein tau has been studied by generating a series of tau constructs differing in one or several of its subdomains: length and composition of the repeat domains, extensions of the repeats in the N- or C-terminal direction, constructs without repeats, assembly vs projection domain, and number of N-terminal inserts. The interaction of the mutant tau proteins with microtubules was judged by several independent methods. (i) Direct binding assays between tau and taxol-stabilized microtubules yield dissociation constants and stoichiometries. (ii) Light scattering and X-ray scattering of assembling microtubule solutions reflect the capacity of tau to promote microtubule nucleation, elongation, and bundling in bulk solution. (iii) Dark field microscopy of assembling microtubules allows one to assess the efficiency of nucleation and bundling separately. The repeat region alone, the N-terminal domains alone, or the C-terminal tail alone binds only weakly to microtubules. However, binding is strongly enhanced by combinations such as the repeat region plus one or both of the flanking regions which could be viewed as "jaws" for tau on the microtubule surface (the proline-rich domain P upstream of the repeats and the "fifth" repeat R' downstream). Such combinations make tau's binding productive in terms of microtubule assembly and stabilization, while the combination of the flanking regions without repeats binds only unproductively. Efficien…

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Tau is a microtubule-associated protein that stabilizes microtubules by interacting with tubulin heterodimers, supporting axonal structure and neuronal morphology.

    “The microtubule-associated protein tau (MAPT) was first identified as a key regulator of microtubule stability and assembly [1]. Tau stabilizes microtubules by interacting with tubulin heterodimers, thereby supporting axonal structure and maintaining neuronal morphology [2–4].”
  • Tau occurs in six different isoforms in the human central nervous system.

    “Tau occurs in six different isoforms in the human central nervous system13, 14.”

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.
