WebAurora B plays a crucial role in ensuring correct chromosome–microtubule attachments by releasing kinetochores in two ways: It weakens the attachment of the outer kinetochore proteins to the microtubule and directly destabilizes the kinetochore-attached microtubule tip (Lampson et al. 2004; Sarangapani et al. 2013).
