Metaphase Spindle Assembly [PDF]

open access: yesBiology, 2017
A microtubule-based bipolar spindle is required for error-free chromosome segregation during cell division. In this review I discuss the molecular mechanisms required for the assembly of this dynamic micrometer-scale structure in animal cells.

The Spindle Assembly Checkpoint [PDF]

open access: yesCurrent Biology, 2012
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.

Mechanisms of Mitotic Spindle Assembly [PDF]

open access: yesAnnual Review of Biochemistry, 2016
Life depends on cell proliferation and the accurate segregation of chromosomes, which are mediated by the microtubule (MT)-based mitotic spindle and ∼200 essential MT-associated proteins. Yet, a mechanistic understanding of how the mitotic spindle is assembled and achieves chromosome segregation is still missing.

Mechanism of spindle assembly in Schizosaccharomyces pombe - The role of microtubule pivoting in spindle assembly [PDF]

open access: yes, 2016
At the onset of cell division microtubules growing from spindle pole bodies (SPB) interact with each other to form the mitotic spindle enabling proper chromosome positioning and segregation. However, the exact mechanism of microtubule dynamics and microtubule associated proteins (MAPs) underlying spindle assembly is still not well understood.

The elegans of spindle assembly [PDF]

open access: yesCellular and Molecular Life Sciences, 2010
The Caenorhabditis elegans one-cell embryo is a powerful system in which to study microtubule organization because this large cell assembles both meiotic and mitotic spindles within the same cytoplasm over the course of 1 h in a stereotypical manner. The fertilized oocyte assembles two consecutive acentrosomal meiotic spindles that function to reduce ...

The spindle assembly checkpoint [PDF]

open access: yesCurrent Biology, 2008
(Current Biology 18, R391–R395; July 22, 2008)Because of an editorial mistake, Figure 1Figure 1 of this Primer shows pairs of kinetochores (indicated by pairs of yellow dots) during telophase, instead of single kinetochores as indicated in the corrected figure that appears here. The journal regrets this error.Figure 1The SAC as a synchronization device(

Meiotic regulation of TPX2 protein levels governs cell cycle progression in mouse oocytes. [PDF]

open access: yesPLoS ONE, 2008
Formation of female gametes requires acentriolar spindle assembly during meiosis. Mitotic spindles organize from centrosomes and via local activation of the RanGTPase on chromosomes.

Spindle Assembly Factor Protection [PDF]

open access: yesMolecular Cell, 2014
In this issue, Song et al. (2014) describe how microtubules and the RAN GTPase/importin-β system collaborate to control timing of HURP action and its turnover via the anaphase promoting complex (APC)-proteasome system, thereby ensuring temporal control of late mitotic events.

RNA stimulates Aurora B kinase activity during mitosis. [PDF]

open access: yesPLoS ONE, 2014
Accurate chromosome segregation is essential for cell viability. The mitotic spindle is crucial for chromosome segregation, but much remains unknown about factors that regulate spindle assembly.

Kinesin-5 Eg5 is essential for spindle assembly and chromosome alignment of mouse spermatocytes

open access: yesCell Division, 2020
Background Microtubule organization is essential for bipolar spindle assembly and chromosome segregation, which contribute to genome stability. Kinesin-5 Eg5 is known to be a crucial regulator in centrosome separation and spindle assembly in mammalian ...
