  1. Phosphorylation of Bub1 by Mph1 promotes Bub1 signaling at the kinetochore to ensure accurate chromosome segregation.
    Title: Phosphorylation of Bub1 by Mph1 promotes Bub1 signaling at the kinetochore to ensure accurate chromosome segregation.
  2. Phosphorylation of the conserved MELT motifs in Spc7 by Mph1 (Mps1) recruits Bub1 and Bub3 to the kinetochore and this is required to maintain the spindle assembly checkpoint signal. [Bub1; Bub3; Spc7; Mph1]
    Title: Phosphodependent recruitment of Bub1 and Bub3 to Spc7/KNL1 by Mph1 kinase maintains the spindle checkpoint.
  3. The Ndc80 hairpin region might act as a platform for the kinetochore recruitment of Mph1.
    Title: The hairpin region of Ndc80 is important for the kinetochore recruitment of Mph1/MPS1 in fission yeast.
  4. Our results highlight the crucial role of Mph1 at kinetochores and suggest that the Mad1-Mad2 complex does not necessarily need to be enriched at kinetochores for functional SAC signaling.
    Title: Mph1 kinetochore localization is crucial and upstream in the hierarchy of spindle assembly checkpoint protein recruitment to kinetochores.
  5. MPS1/Mph1 phosphorylates the kinetochore protein KNL1/Spc7 to recruit spindle assembly checkpoint proteins and promote chromosome alignment.
    Title: MPS1/Mph1 phosphorylates the kinetochore protein KNL1/Spc7 to recruit SAC components.
  6. A kinase-dead allele of the fission yeast MPS1 homolog (Mph1) is checkpoint defective and levels of anaphase promoting complex-associated Mad2 and Mad3 are dramatically reduced in this mutant.
    Title: Kinase activity of fission yeast Mph1 is required for Mad2 and Mad3 to stably bind the anaphase promoting complex.
