Eine lebende Zelle ist von einem dichten Geflecht von Polymerfasern durchzogen, die unter anderem dafür zuständig sind, verschiedene Zellbestandteile an ihre Bestimmungsorte in der Zelle zu ziehen: sie trennen bei der Zellteilung die für die beiden neuen Zellen gedachten Chromosomen voneinander, oder transportieren Zellorganellen und Bläschen mit Substanzen an ihren Bestimmungsort. Ein Forschungsteam um Michel Steinmetz (Paul Scherrer Institut, Villigen, Schweiz) und Anna Akhmanova (Erasmus Medical Center, Rotterdam, Niederlande) hat nun einen Mechanismus aufgeklärt, der dazu beiträgt, dass die Enden der Polymerfasern Chromosomen, Zellorganellen und andere Zellbestandteile spezifisch erkennen und sich mit ihnen verbinden können.
