Samurai sword sets spindle size

Cell. 2011 Dec 9;147(6):1224-5. doi: 10.1016/j.cell.2011.11.039.


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.
