Biology, 2016 Anaphase B spindle elongation is characterized by the sliding apart of overlapping antiparallel interpolar (ip) microtubules (MTs) as the two opposite spindle poles separate, pulling along disjoined sister chromatids, thereby contributing to chromosome ...

Spatiotemporal control of mitotic exit during anaphase by an aurora B-Cdk1 crosstalk
eLife, 2019 According to the prevailing ‘clock’ model, chromosome decondensation and nuclear envelope reformation when cells exit mitosis are byproducts of Cdk1 inactivation at the metaphase-anaphase transition, controlled by the spindle assembly checkpoint. However,

Anaphase A: Disassembling Microtubules Move Chromosomes toward Spindle Poles
Biology, 2017 The separation of sister chromatids during anaphase is the culmination of mitosis and one of the most strikingly beautiful examples of cellular movement.

Bypassing anaphase by fission yeast cut9 mutation: requirement of cut9+ to initiate anaphase. [PDF]
The Journal of cell biology, 1994 A novel anaphase block phenotype was found in fission yeast temperature-sensitive cut9 mutants. Cells enter mitosis with chromosome condensation and short spindle formation, then block anaphase, but continue to progress into postanaphase events such as degradation of the spindle, reformation of the postanaphase cytoplasmic microtubule arrays, septation,

Molecular Biology of the Cell, 2019 Spindle microtubules, whose dynamics vary over time and at different locations, cooperatively drive chromosome segregation. Measurements of microtubule dynamics and spindle ultrastructure can provide insight into the behaviors of microtubules, helping ...

The anaphase-promoting complex: proteolysis in mitosis and beyond. [PDF]
Molecular Cell, 2002 Key events in mitosis such as sister chromatid separation and subsequent inactivation of cyclin-dependent kinase 1 are regulated by ubiquitin-dependent proteolysis. These events are mediated by the anaphase-promoting complex (APC), a cell cycle-regulated ubiquitin ligase that assembles multiubiquitin chains on regulatory proteins such as securin and ...

Nature Communications, 2018 Female meiotic divisions are asymmetric with the formation of large oocytes and small polar bodies, thought to result from cortical spindle placement before anaphase.

Chromosome Bridges Maintain Kinetochore-Microtubule Attachment throughout Mitosis and Rarely Break during Anaphase. [PDF]
PLoS ONE, 2016 Accurate chromosome segregation during cell division is essential to maintain genome stability, and chromosome segregation errors are causally linked to genetic disorders and cancer.

A Wee1 checkpoint inhibits anaphase onset [PDF]
Journal of Cell Biology, 2013 The budding yeast Wee1 kinase Swe1 restrains the metaphase-to-anaphase transition by preventing the Cdk1-dependent phosphorylation and activation of APCCdc20.

Blocking microtubule deacetylation inhibits anaphase chromosome movements in crane-fly spermatocytes. [PDF]
PLoS ONEChromosome movement speeds during anaphase are regulated by depolymerization of microtubules. Several models describe chromosome movement during cell division but none of them consider post-translational modifications of tubulin, even though such ...
