Tau domains, phosphorylation, and interactions with microtubules

Abstract

We consider the interactions of tau protein with microtubules from two points of view, phosphorylation and domain structure. Tau can be phosphorylated at many sites and by several kinases, notably by proline-directed kinases (MAPK, GSK-3, cdk5) which generate Alzheimer-like antibody epitopes. Other kinases phosphorylate Ser 262, a site that has a particularly pronounced influence on the affinity of tau for microtubules. All of these sites can be cleared by phosphatases PP-2a and calcineurin. The site Ser262 lies within the repeat domain of tau. However, when probing the domains of tau for their effects on microtubule binding, nucleation, assembly, or bundling, the repeat domain has only a weak influence. Whereas the repeat domain of tau binds to microtubules with low affinity, repeat-less tau binds strongly yet unproductively in terms of microtubule assembly. Productive binding of tau to microtubules depends on the combination of (some) repeats with the flanking regions, as if the flanking regions acted as "jaws" for the proper positioning of tau on the microtubule surface.

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.
