Bub1 Kinase Targets Sgo1 to Ensure Efficient Chromosome Biorientation in Budding Yeast Mitosis (2007)

Josefin Fernius, Kevin G. Hardwick

During cell division all chromosomes must be segregated accurately to each daughter cell. Errors in this process give rise to aneuploidy, which leads to birth defects and is implicated in cancer...

The Spindle Checkpoint of Budding Yeast Depends on a Tight Complex between the Mad1 and Mad2 Proteins

Chen, Rey-Huei, Brady, D. Michelle, Smith, Dana, Murray, Andrew W., Hardwick, Kevin G.

The spindle checkpoint arrests the cell cycle at metaphase in the presence of defects in the mitotic spindle or in the attachment of chromosomes to the spindle. When spindle assembly is disrupted,...

Distinct Chromosome Segregation Roles for Spindle Checkpoint Proteins

Warren, Cheryl D., Brady, D. Michelle, Johnston, Raymond C., Hanna, Joseph S., Hardwick, Kevin G., Spencer, Forrest A.

The spindle checkpoint plays a central role in the fidelity of chromosome transmission by ensuring that anaphase is initiated only after kinetochore-microtubule associations of all sister chromatid...

Fission Yeast Mad3p Is Required for Mad2p To Inhibit the Anaphase-Promoting Complex and Localizes to Kinetochores in a Bub1p-, Bub3p-, and Mph1p-Dependent Manner

Millband, David N., Hardwick, Kevin G.

The spindle checkpoint delays the metaphase-to-anaphase transition in response to spindle and kinetochore defects. Genetic screens in budding yeast identified the Mad and Bub proteins as key...

Kinetochore Targeting of Fission Yeast Mad and Bub Proteins Is Essential for Spindle Checkpoint Function but Not for All Chromosome Segregation Roles of Bub1p†

Vanoosthuyse, Vincent, Valsdottir, Rebekka, Javerzat, Jean-Paul, Hardwick, Kevin G.

Several lines of evidence suggest that kinetochores are organizing centers for the spindle checkpoint response and the synthesis of a “wait anaphase” signal in cases of incomplete or improper...

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 Function

Kadura, Sheila, He, Xiangwei, Vanoosthuyse, Vincent, Hardwick, Kevin G., Sazer, Shelley

During mitosis, the spindle assembly checkpoint (SAC) responds to faulty attachments between kinetochores and the mitotic spindle by imposing a metaphase arrest until the defect is corrected, thereby...

Mad3 KEN Boxes Mediate both Cdc20 and Mad3 Turnover, and Are Critical for the Spindle Checkpoint

King, Emma M.J., Hardwick, Kevin G.

Mitotic progression is controlled by proteolytic destruction of securin and cyclin. The mitotic E3 ubiquitin ligase, known as the anaphase promoting complex or cyclosome (APC/C), in partnership with...

Shugoshin 2 Regulates Localization of the Chromosomal Passenger Proteins in Fission Yeast Mitosis

Vanoosthuyse, Vincent, Prykhozhij, Sergey, Hardwick, Kevin G.

Fission yeast has two members of the Shugoshin family, Sgo1 and Sgo2. Although Sgo1 has clearly been established as a protector of centromere cohesion in meiosis I, the roles of Sgo2 remain elusive....

Novel sfi1 Alleles Uncover Additional Functions for Sfi1p in Bipolar Spindle Assembly and Function

Anderson, Victoria E., Prudden, John, Prochnik, Simon, Giddings, Thomas H., Hardwick, Kevin G.

A variety of spindle and kinetochore defects have been shown to induce a mitotic delay through activation of the spindle checkpoint. With the aim of identifying novel mitotic defects we carried out a...

Ipl1p-dependent phosphorylation of Mad3p is required for the spindle checkpoint response to lack of tension at kinetochores

King, Emma M.J., Rachidi, Najma, Morrice, Nick, Hardwick, Kevin G., Stark, Michael J.R.

The spindle checkpoint delays anaphase onset until all chromosomes are correctly attached to microtubules. Ipl1 protein kinase (Aurora B) is required to correct inappropriate...
