Meiotic cells escape prolonged spindle checkpoint activity through kinetochore silencing and slippage.

open access: yesPLoS Genetics, 2023
To prevent chromosome mis-segregation, a surveillance mechanism known as the spindle checkpoint delays the cell cycle if kinetochores are not attached to spindle microtubules, allowing the cell additional time to correct improper attachments.

Prime movers : mechanochemistry of mitotic kinesins [PDF]

open access: yes, 2014
Mitotic spindles are self-organizing protein machines that harness teams of multiple force generators to drive chromosome segregation. Kinesins are key members of these force-generating teams.

Mitotic spindle proteomics in Chinese hamster ovary cells.

open access: yesPLoS ONE, 2011
Mitosis is a fundamental process in the development of all organisms. The mitotic spindle guides the cell through mitosis as it mediates the segregation of chromosomes, the orientation of the cleavage furrow, and the progression of cell division.

Fission yeast bub1 is a mitotic centromere protein essential for the spindle checkpoint and the preservation of correct ploidy through mitosis [PDF]

open access: yes, 1998
The spindle checkpoint ensures proper chromosome segregation by delaying anaphase until all chromosomes are correctly attached to the mitotic spindle.

HSP70 is required for the proper assembly of pericentriolar material and function of mitotic centrosomes

open access: yesCell Division, 2019
Background At the onset of mitosis, the centrosome expands and matures, acquiring enhanced activities for microtubule nucleation and assembly of a functional bipolar mitotic spindle.

Mechanisms and Molecules of the Mitotic Spindle [PDF]

open access: yesCurrent Biology, 2004
In all eukaryotes, morphogenesis of the microtubule cytoskeleton into a bipolar spindle is required for the faithful transmission of the genome to the two daughter cells during division. This process is facilitated by the intrinsic polarity and dynamic properties of microtubules and involves many proteins that modulate microtubule organization and ...

Length-dependent anisotropic scaling of spindle shape [PDF]

open access: yes, 2014
Spindle length varies dramatically across species and during early development to segregate chromosomes optimally. Both intrinsic factors, such as regulatory molecules, and extrinsic factors, such as cytoplasmic volume, determine spindle length scaling ...

Endoplasmic reticulum membranes are continuously required to maintain mitotic spindle size and forces

open access: yesLife Science Alliance, 2023
Using microinjection approaches in Drosophila embryos, Araújo et al reveal that acute disruption of the ER at centrosome-proximal sites perturbs the architecture of the mitotic spindle, with a direct impact on nuclear positioning.

Latrunculin A delays anaphase onset in fission yeast by disrupting an ase1-independent pathway controlling mitotic spindle stability [PDF]

open access: yes, 2008
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.

Smurf2 as a novel mitotic regulator: From the spindle assembly checkpoint to tumorigenesis

open access: yesCell Division, 2009
The execution of the mitotic program with high fidelity is dependent upon precise spatiotemporal regulation of posttranslational protein modifications.
