Reverse Engineering of the Spindle Assembly Checkpoint
The Spindle Assembly Checkpoint (SAC) is an intracellular mechanism that ensures proper chromosome segregation. By inhibiting Cdc20, a co-factor of the Anaphase Promoting Complex (APC), the checkpoint arrests the cell cycle until all chromosomes are properly attached to the mitotic spindle. Inhibition of Cdc20 is mediated by a conserved network of interacting proteins. The individual functions ...
متن کاملThe spindle assembly checkpoint
Italian in 1954, so Imanishi turned to the exploration of the unexplored wide range of Karakorum Himalayas, traversing the three major glaciers in 1955. Then, in 1958, Imanishi and Itani went to Africa for the first time. In the same year, Nishibori led the all-Japanese team which succeeded in the first over-wintering stay in Antarctica. Kuwabara led the Himalayan expedition of AACK to the firs...
متن کاملThe Spindle Assembly Checkpoint
During mitosis and meiosis, the spindle assembly checkpoint acts to maintain genome stability by delaying cell division until accurate chromosome segregation can be guaranteed. Accuracy requires that chromosomes become correctly attached to the microtubule spindle apparatus via their kinetochores. When not correctly attached to the spindle, kinetochores activate the spindle assembly checkpoint ...
متن کاملKinetochore stretching inactivates the spindle assembly checkpoint
The spindle assembly checkpoint (SAC) monitors the attachment of microtubules to the kinetochore and inhibits anaphase when microtubule binding is incomplete. The SAC might also respond to tension; however, how cells can sense tension and whether its detection is important to satisfy the SAC remain controversial. We generated a HeLa cell line in which two components of the kinetochore, centrome...
متن کاملNoise resistance in the spindle assembly checkpoint
Genetically identical cells vary in the amount of expressed proteins even when growing under the same conditions. It is not yet clear how cellular information processing copes with such stochastic fluctuations in protein levels. Here we examine the capacity of the spindle assembly checkpoint to buffer temporal fluctuations in the expression of Cdc20, a critical checkpoint target whose activity ...
