説明

<jats:title>Tackling microtubule-tau interactions</jats:title> <jats:p> Alzheimer's disease is a major cause of death in the elderly. Disease progression is associated with the accumulation of neurofibrillary tangles composed of tau, a protein important for neuronal development and function. Tangle formation is preceded by phosphorylation events that cause tau to dissociate from its native binding partner, microtubules. Microtubule-tau interactions have been mysterious. Kellogg <jats:italic>et al.</jats:italic> used cryo–electron microscopy and molecular modeling to show how tau interacts with the outer surface of the microtubule, stapling together tubulin subunits and thus stabilizing the polymer. A key tau amino acid within the tightly bound segment between tubulin subunits corresponds to a clinically relevant site of tau phosphorylation, explaining the competition between microtubule interaction and tau aggregation. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6394" page="1242" related-article-type="in-this-issue" vol="360" xlink:href="10.1126/science.aat1780">1242</jats:related-article> </jats:p>
