Insight into microtubule disassembly by kinesin-13s from the structure of Kif2C bound to tubulin

Kinesin-13s are microtubule depolymerizing enzymes. Here the authors present the crystal structure of a DARPin fused construct comprising the short neck region and motor domain of kinesin-13 in complex with an αβ-tubulin heterodimer, which shows that kinesin-13 functions by stabilizing a curved tubulin conformation.
