Phosphorylation of mitotic kinesin-like protein 2 by polo-like kinase 1 is required for cytokinesis [PDF]
We have investigated the function of mitotic kinesin-like protein (MKlp) 2, a kinesin localized to the central spindle, and demonstrate that its depletion results in a failure of cleavage furrow ingression and cytokinesis, and disrupts localization of ...

Fission yeast cells undergo nuclear division in the absence of spindle microtubules. [PDF]
Mitosis in eukaryotic cells employs spindle microtubules to drive accurate chromosome segregation at cell division. Cells lacking spindle microtubules arrest in mitosis due to a spindle checkpoint that delays mitotic progression until all chromosomes ...

Relocation of Aurora B from centromeres to the central spindle at the metaphase to anaphase transition requires MKlp2 [PDF]
Mitotic kinases of the Polo and Aurora families are key regulators of chromosome segregation and cytokinesis. Here, we have investigated the role of MKlp1 and MKlp2, two vertebrate mitotic kinesins essential for cytokinesis, in the spatial regulation of ...

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]
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 ...

Mitotic spindle proteomics in Chinese hamster ovary cells.
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.

Bub1 is a fission yeast kinetochore scaffold protein, and is sufficient to recruit other spindle checkpoint proteins to ectopic sites on chromosomes [PDF]
The spindle checkpoint delays anaphase onset until all chromosomes have attached in a bi-polar manner to the mitotic spindle. Mad and Bub proteins are recruited to unattached kinetochores, and generate diffusible anaphase inhibitors.

Smurf2 as a novel mitotic regulator: From the spindle assembly checkpoint to tumorigenesis
The execution of the mitotic program with high fidelity is dependent upon precise spatiotemporal regulation of posttranslational protein modifications.

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.

Mitotic centromere-associated kinesin (MCAK) : a potential cancer drug target [PDF]
The inability to faithfully segregate chromosomes in mitosis results in chromosome instability, a hallmark of solid tumors. Disruption of microtubule dynamics contributes highly to mitotic chromosome instability.
