Microtubule end conversion mediated by motors and diffusing proteins with no intrinsic microtubule end-binding activity

Abstract

During cell division, it is currently unclear how kinetochores transit from lateral microtubule attachment to durable association to dynamic microtubule plus ends. Here, using in vitro reconstitution and computer modeling, the authors provide biophysical mechanism for microtubule end-conversion driven by two kinetochore components, CENP-E and Ndc80 complex
