How Aurora B and the spindle assembly checkpoint pathway collaborate during every cell cycle to accurately attach every single pair of sister chromatids to the mitotic spindle in the correct, bioriented manner?

#Unit 2. Cellular Organization
  1. Aurora B phosphorylate microtubule-binding component of the kinetochore, the Ndc80 complex, leads to the generation of attached kinetochores, which are recognized by the spindle assembly checkpoint pathway.
  2. Aurora B phosphorylate microtubule-binding component of the kinetochore, the Ndc80 complex, leads to the generation of unattached kinetochores, which are recognized by the spindle assembly checkpoint pathway.
  3. Aurora B dephosphorylate microtubule-binding component of the kinetochore, the Ndc80 complex, leads to the generation of unattached kinetochores, which are recognized by the spindle assembly checkpoint pathway.
  4. Aurora B ubiquitinylates microtubule-binding component of the kinetochore, the Ndc80 complex, leads to the degradation of unattached kinetochores, which are recognized by the spindle assembly checkpoint pathway.
