Movie S1.

Kinetochores retain Mps1 when tracking with disassembling microtubule tips. A kinetochore particle (from SBY15285) tracks with the disassembling tip of a microtubule (green) while carrying Mps1-SNAP-549 (cyan) and Mtw1-CLIP-647 (red). Colors are deliberately offset; the cyan-red pair is a colocalized, dual-color kinetochore particle.
