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.

Latrunculin A delays anaphase onset in fission yeast by disrupting an ase1-independent pathway controlling mitotic spindle stability [PDF]
It has been proposed previously that latrunculin A, an inhibitor of actin polymerization, delays the onset of anaphase by causing spindle misorientation in fission yeast.

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

Mad3 KEN boxes mediate both Cdc20 and Mad3 turnover, and are critical for the spindle checkpoint [PDF]
Mitotic progression is controlled by proteolytic destruction of securin and cyclin. The mitotic E3 ubiquitin ligase, known as the anaphase promoting complex or cyclosome (APC/C), in partnership with its activators Cdc20p and Cdh1p, targets these proteins

On the regulation of chromosome segregation in human cells : implications of Bub1 Kinase inhibition during cell division [PDF]
The maintenance of correct chromosome number (euploidy) during cell division is essential for health. Loss of euploidy is observed in most cancers and is linked to tumorigenesis.

Characterization of mitotic checkpoint complexes [PDF]
In eukaryotes, chromosome segregation critically depends on the establishment of productive contacts between kinetochores (KTs), specialized chromosomal structures, and the spindle microtubules (MTs).

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 ...

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.
