title: Dam1 complexes go it alone on disassembling microtubules.
abstract: Kinetochores maintain a mechanical grip on disassembling microtubule plus ends, possibly through a 16-member Dam1 ring that acts as a sliding clamp. It turns out, however, that a ring is not required for maintaining grip: individual Dam1 complexes in vitro can diffuse on the microtubule lattice and track shortening microtubule tips.
