- Kinetochore targeting of fission yeast Mad and Bub proteins is essential for spindle checkpoint function but not for all chromosome segregation roles of Bub1pVincent Vanoosthuyse
Wellcome Trust Centre for Cell Biology, ICMB, University of Edinburgh, Edinburgh EH9 3JR, United Kingdom
Mol Cell Biol 24:9786-801. 2004..Surprisingly, neither this domain nor kinetochore localization is required for other functions of Bub1p in chromosome segregation...

Wellcome Trust Centre for Cell Biology, Institute of Cell Biology, University of Edinburgh, Edinburgh EH9 3JR, United Kingdom
Genes Dev 23:2799-805. 2009..2887-2899) identify budding yeast Fin1p as a kinetochore-localized regulator of PP1 activity toward checkpoint targets. Here we review recent mechanistic insights and propose a working model for spindle checkpoint silencing...

Wellcome Trust Centre for Cell Biology, Institute of Cell Biology, University of Edinburgh, Edinburgh EH9 3JR, UK
Curr Biol 19:1176-81. 2009..We propose that PP1(Dis2)-mediated dephosphorylation of checkpoint components forms a novel spindle checkpoint silencing mechanism...
- Shugoshin 2 regulates localization of the chromosomal passenger proteins in fission yeast mitosisVincent Vanoosthuyse
Wellcome Trust Centre for Cell Biology, University of Edinburgh, Edinburgh EH9 3JR, UK
Mol Biol Cell 18:1657-69. 2007..Taken together, our results demonstrate that Sgo2 is important for chromosome biorientation and that it controls docking of the Passenger proteins on chromosomes in early mitotic cells...
- Bub1 and the multilayered inhibition of Cdc20-APC/C in mitosisVincent Vanoosthuyse
Wellcome Trust Centre for Cell Biology, University of Edinburgh, Edinburgh EH9 3JR, Scotland, UK
Trends Cell Biol 15:231-3. 2005..How the checkpoint machinery actually inhibits the APC/C is still unclear. A new paper by Tang and coworkers helps further our understanding of this complex and fundamental process...

- The A78V mutation in the Mad3-like domain of Schizosaccharomyces pombe Bub1p perturbs nuclear accumulation and kinetochore targeting of Bub1p, Bub3p, and Mad3p and spindle assembly checkpoint functionSheila Kadura
Verna and Marrs McClean Department of Biochemistry and Molecular Biology, Baylor College of Medicine, Houston, TX 77030, USA
Mol Biol Cell 16:385-95. 2005..These data indicate that Bub1p-A78V is defective in both nuclear accumulation and kinetochore targeting and that a threshold level of nuclear Bub1p is necessary for the nuclear accumulation of Bub3p and Mad3p...
