Popis: Phosphorylation of the Ndc80 kinetochore protein by the Ipl1/Aurora B kinase reduces its microtubule binding activity in vitro. We found that kinetochore-bound Ndc80 is phosphorylated on Ipl1 sites in vivo, but this phosphorylation is not essential. Instead, we show that additional Ipl1 targets contribute to segregation and the spindle checkpoint.
