    1. Spindle checkpoint proteins are severely depleted from unattached kinetochores in fission yeast cells lacking Bub3p.
      Title: Bub3p facilitates spindle checkpoint silencing in fission yeast.
    2. find that Bub3 is also dispensable for shugoshin localization to the centromeres, which is the second known function of Bub1.
      Title: Bub1 and Bub3 promote the conversion from monopolar to bipolar chromosome attachment independently of shugoshin.
    3. the bub3 mutation only weakly affected the stability of minichromosome Ch16 compared with other spindle assembly checkpoint mutants
      Title: Schizosaccharomyces pombe Bub3 is dispensable for mitotic arrest following perturbed spindle formation.
    4. Bub1p-A78V is defective in both nuclear accumulation and kinetochore targeting; a threshold level of nuclear Bub1p is necessary for the nuclear accumulation of Bub3p and Mad3p
