Spindle assembly checkpoint protein dynamics reveal conserved and unsuspected roles in plant cell division. [PDF]
BACKGROUND: In eukaryotes, the spindle assembly checkpoint (SAC) ensures that chromosomes undergoing mitosis do not segregate until they are properly attached to the microtubules of the spindle.

Spindle assembly checkpoint, aneuploidy and tumorigenesis [PDF]
Faithfully distributing chromosomes into two daughter cells in mitosis is essential for the maintenance of the integrity of the genome genome. The fidelity is achieved through a number of cellular processes among which is the spindle assembly checkpoint (SAC), an elaborate molecular pathway that monitors the attachment of microtubules to kinetochores ...

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.

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

Noise resistance in the spindle assembly checkpoint [PDF]
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

Kinetic framework of spindle assembly checkpoint signalling [PDF]
The mitotic spindle assembly checkpoint (SAC) delays anaphase onset until all chromosomes have attached to both spindle poles. Here, we investigated SAC signalling kinetics in response to acute detachment of individual chromosomes using laser microsurgery. Most detached chromosomes delayed anaphase until they had realigned to the metaphase plate.

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

Checkpoint kinase 2 (CHK2) plays an important role in safeguarding the mitotic progression, specifically the spindle assembly, though the mechanism of regulation remains poorly understood.

TRIP13 is a protein-remodeling AAA+ ATPase that catalyzes MAD2 conformation switching
The AAA+ family ATPase TRIP13 is a key regulator of meiotic recombination and the spindle assembly checkpoint, acting on signaling proteins of the conserved HORMA domain family.

Requirement for proteolysis in spindle assembly checkpoint silencing [PDF]
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 ...
