摘要
The highly orchestrated movements of chromosomes during mitosis depend on the formation of stable connections between microtubules and kinetochores. How kinetochores generate these linkages to harness the forces produced by dynamic microtubule plus-ends remains unknown. Three recent studies make significant progress on this front, by identifying a third component of the kinetochore-associated Ska (spindle and kinetochore associated) complex and demonstrating that the complex is required to generate stable kinetochore-microtubule attachments during mitosis in human cells.
