title: Samurai sword sets spindle size.
abstract: Although the parts list is nearly complete for many cellular structures, mechanisms that control their size remain poorly understood. Loughlin and colleagues now show that phosphorylation of a single residue of katanin, a microtubule-severing protein, largely accounts for the difference in spindle length between two closely related frogs.
