The spindle checkpoint in Xenopus Laevis
Frontiers in Bioscience, 2008The spindle checkpoint ensures accurate chromosome segregation by delaying anaphase onset until all kinetochores have properly established bipolar attachment to spindle microtubules. This mechanism is important for all eukaryotic cells and is evolutionarily conserved.

Spindle-Assembly Checkpoint and Gastrointestinal Cancer
New England Journal of Medicine, 2011To the Editor: Rio Frio et al. (Dec. 30 issue)1 report on a germline homozygous mutation in the spindle-assembly checkpoint gene BUB1B in a patient with a nonclassic form of the mosaic variegated aneuploidy syndrome, resulting in reduced expression, increased levels of constitutive aneuploidy, and multiple gastrointestinal neoplasms starting at 34 ...

The spindle checkpoint: tension versus attachment
Trends in Cell Biology, 2005The spindle checkpoint ensures the fidelity of chromosome segregation by preventing cell-cycle progression until all the chromosomes make proper bipolar attachments to the mitotic spindle and come under tension. Despite significant advances in our understanding of spindle checkpoint function, the primary signal that activates the spindle checkpoint ...

The spindle assembly checkpoint in budding yeast
1997Publisher Summary This chapter discusses the spindle assembly checkpoint in budding yeast. As cells proceed through cycles of growth and division they are often challenged by environmental insult and injury as well as spontaneous errors in cellular processes. The response to cell damage requires that cells sense the damage, arrest the cell cycle, and

Analyzing the Spindle Checkpoint in Yeast and Frogs
2004The spindle checkpoint is an evolutionarily conserved regulatory mechanism that ensures correct segregation of chromosomes at mitosis and meiosis. The kinetochore plays an integral role in spindle checkpoint signaling by integrating chromosome attachment to the spindle with cell cycle progression. A single kinetochore can inhibit cell cycle progression

The kinetochore and spindle checkpoint in vertebrate cells
Frontiers in Bioscience, 2008The centromere is a specialized region of eukaryotic chromosomes that is essential for faithful chromosome segregation during mitosis and meiosis. A kinetochore is assembled at the centromere of each chromatid of a replicated chromosome and forms a dynamic interface with microtubules of the mitotic spindle.
