The spindle assembly checkpoint
Current Opinion in Cell Biology, 1996The spindle assembly checkpoint monitors proper chromosome attachment to spindle microtubules and is conserved from yeast to humans. Checkpoint components reside on kinetochores of chromosomes and show changes in phosphorylation and localization as cells proceed through mitosis.

The Spindle Assembly and Spindle Position Checkpoints
Annual Review of Genetics, 2003▪ Abstract The mitotic spindle segregates chromosomes to opposite ends of the cell in preparation for cell division. Chromosome attachment to the spindle is monitored by the spindle assembly checkpoint, and at least in yeast cells, penetration of one spindle pole into the bud is monitored by the spindle position checkpoint.

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 ...

Cdh1 is an antagonist of the spindle assembly checkpoint
Cellular Signalling, 2014The spindle assembly checkpoint (SAC) monitors unsatisfied connections of microtubules to kinetochores and prevents anaphase onset by inhibition of the ubiquitin ligase E3 anaphase-promoting complex or cyclosome (APC/C) in association with the activator Cdc20.

Slipping past the spindle assembly checkpoint
Nature Cell Biology, 2013Error-free genome segregation depends on the spindle assembly checkpoint (SAC), a signalling network that delays anaphase onset until chromosomes have established proper spindle attachments. Three reports now quantitatively examine the sensitivity and robustness of the SAC response.

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

Sister chromatid tension and the spindle assembly checkpoint
Current Opinion in Cell Biology, 2009The spindle assembly checkpoint (SAC) is a feedback control system that monitors the state of kinetochore/microtubule attachment during mitosis and halts cell cycle progression until all chromosomes are properly aligned at the metaphase plate. The state of chromosome-microtubule attachment is implicated as a crucial factor in the checkpoint response ...

Analysis of the Spindle-Assembly Checkpoint in HeLa Cells [PDF]
, 2004 The spindle-assembly checkpoint involves signaling at kinetochores, which leads to the arrest of mitotic progression in the absence of microtubule attachment or spindle tension. Here, we detail procedures for the analysis of the spindle-assembly checkpoint in adherent mammalian cells.

Germline mutations in BUB1B, encoding BUBR1, one of the crucial components of the spindle assembly checkpoint (SAC), have been shown to cause variable phenotypes, including the recessive mosaic variegated aneuploidy (MVA) syndrome, which predisposes to ...

Determinants of robustness in spindle assembly checkpoint signalling
Nature Cell Biology, 2013The spindle assembly checkpoint is a conserved signalling pathway that protects genome integrity. Given its central importance, this checkpoint should withstand stochastic fluctuations and environmental perturbations, but the extent of and mechanisms underlying its robustness remain unknown.
