Modeling Dual Pathways for the Metazoan Spindle Assembly Checkpoint [PDF]
Proc. Natl. Acad. Sci. 103 16758-16763 (2006), 2006 Using computational modelling, we investigate mechanisms of signal transduction focusing on the spindle assembly checkpoint where a single unattached kinetochore is able to signal to prevent cell cycle progression. This inhibitory signal switches off rapidly once spindle microtubules have attached to all kinetochores.

Spindle assembly checkpoint: the third decade [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2011 The spindle assembly checkpoint controls cell cycle progression during mitosis, synchronizing it with the attachment of chromosomes to spindle microtubules. After the discovery of themitotic arrest deficient(MAD) andbudding uninhibited by benzymidazole(BUB) genes as crucial checkpoint components in 1991, the second decade of checkpoint studies (2001 ...

Requirement for proteolysis in spindle assembly checkpoint silencing [PDF]
Cell Cycle, 2010 Anaphase initiation requires ubiquitin-dependent proteolysis of crucial substrates through activation of the ubiquitin ligase Anaphase promoting Complex/Cyclosome (ApC/C) in association with its coactivator Cdc20. To prevent chromosome segregation errors, effector proteins of a safeguard mechanism called spindle assembly checkpoint (SAC), Mad2 and ...

Some assembly required: Redefining the mitotic checkpoint
Molecular & Cellular Oncology, 2017 The spindle assembly checkpoint (also known as the spindle or mitotic checkpoint) is a surveillance system that ensures fidelity of chromosome segregation.

PLoS ONE, 2010 Microtubule-targeting drugs induce mitotic delay at pro-metaphase by preventing the spindle assembly checkpoint to be satisfied. However, especially after prolonged treatments, cells can escape this arrest in a process called mitotic slippage.

Spindle assembly checkpoint is sufficient for complete Cdc20 sequestering in mitotic control [PDF]
Comput Struct Biotechnol J. 2015 Apr 9;13:320-8, 2016 The spindle checkpoint assembly (SAC) ensures genome fidelity by temporarily delaying anaphase onset, until all chromosomes are properly attached to the mitotic spindle. The SAC delays mitotic progression by preventing activation of the ubiquitin ligase anaphase-promoting complex (APC/C) or cyclosome; whose activation by Cdc20 is required for sister ...

No stretch for spindle assembly checkpoint [PDF]
The Journal of Cell Biology, 2008 ![][1] Kinetochores (red) attach to the spindle (green), whereas chromatin (blue) is largely excluded. Dividing cells aren't quite as obsessed with quality control as previously thought, according to results from [O'Connell and colleagues][2].

Modeling potent pathways for APC/C inhibition: pivotal roles for MCC and BubR1 [PDF]
OMICS: A Journal of Integrative Biology. May 2015, 19(5): 294-305, 2016 The highly conserved spindle assembly checkpoint (SAC) ensures that the sister chromatids of the duplicated genome are not separated and distributed to the spindle poles before all chromosomes have been properly linked to the microtubules of the mitotic spindle.

MAP kinase meets mitosis: A role for Raf Kinase Inhibitory Protein in spindle checkpoint regulation
Cell Division, 2007 Raf Kinase Inhibitory Protein (RKIP) is an evolutionarily conserved protein that functions as a modulator of signaling by the MAP kinase cascade.

Accurate chromosome segregation by probabilistic self-organization [PDF]
BMC Biology 2015 13:65, 2014 Background: For faithful chromosome segregation during cell division, correct attachments must be established between sister chromosomes and microtubules from opposite spindle poles through kinetochores (chromosome bi-orientation). Incorrect attachments of kinetochore microtubules (kMTs) lead to chromosome mis-segregation and aneuploidy, which is often
