Live-imaging of mitotic cells expressing EB1-GFP demonstrates that APC(1-1450) compromises the dynamics of EB1-comets, increasing the frequency of EB1-GFP pausing. Together these data provide novel insight into how APC may regulate mitotic spindle function and how errors in chromosome segregation are tolerated in tumor cells.

Huang, J., Raff, J. W. The disappearance of cyclin B at the end of mitosis is to the spindle poles and has a role in mitotic spindle checkpoint inactivation. J. Cell

It inhibits the formation of mitotic spindle. It plays a crucial role in a living organism's life cycle. However The mitotic spindle is composed of microtubule proteins that slowly increase in length during the The checkpoint kinase 1 (Chk1) is known for its role in DNA damage response, especially the G2/M and the mitotic spindle checkpoint, supporting the idea of an The spindle apparatus is a network of microtubules that forms within a dividing eukaryotic cell. Some of these microtubules attach to the cell walls, others attach Spindle fibers are microscopic protein structures that help divide chromosomes during cell division.

Mitotic spindle: focus on the function of huntingtin. Godin JD(1), Humbert S. Author information: (1)Institut Curie, Orsay, France. Mitotic spindle assembly and orientation are tightly regulated to allow the appropriate segregation of genetic material and cell fate determinants during symmetric and asymmetric divisions. 2011-06-01 · Huntingtin modulates mitotic spindle orientation in cultured cells and in cortical progenitors, thus favoring neuronal differentiation. • The function of huntingtin during spindle orientation is conserved in Drosophila. • Components of the machinery responsible for mitotic spindle orientation have already been implicated in human diseases. To further characterize spindle pole coalescence in polyploid NBs, we used Plp and Cnn to label centrioles and PCM. Mitotic polyploid NBs contained condensed chromosomes arranged in a multilobed configuration separating large spindle poles, which could be visualized as large Cnn structures containing multiple Plp-positive dots (Fig.

Investigating mitotic spindle assembly and function in vitro using Xenopus laevis egg extracts. Eva Hannak 1 & Rebecca Heald 1 Function.

Required for the execution of the mitotic checkpoint which monitors the process of kinetochore-spindle attachment and delays the onset of anaphase when this process is not complete. It inhibits the activity of the anaphase promoting complex by sequestering CDC20 until all chromosomes are aligned at the metaphase plate.1 Publication

Mitotic spindle orientation can influence tissue organization and vice versa. Cells orient their spindles by rotating them parallel or perpendicular to the cell – and hence the tissue – axis. Spindle orientation in turn controls the placement of daughter cells within a tissue, influencing tissue morphology. Recent findings implicating tumor suppressor proteins in spindle orientation bring

Microtubules are nucleated from a crystalline array of proteins organized in the nuclear envelope, known as the spindle pole body in yeast (analogous to the centrosome in larger eukaryotes). The spindle has two classes of nuclear microtubules: kinetochore microtubules and interpolar matid separation and spindle elongation can occur to seg-regate the chromosomes. Finally, after spindle elongation, the spindle breaks down as the cells exit mitosis.

The Saccharomyces cerevisiae mitotic spindle in budding yeast is exemplified by its simplicity and elegance. Microtubules are nucleated from a crystalline array of proteins organized in the nuclear envelope, known as the spindle pole body in yeast (analogous to the centrosome in larger eukaryotes).

Protein phosphorylation has long been implicated in controlling spindle function and chromosome segregation, and genetic studies have identified several protein kinases and phosphatases that are likely to regulate these processes. Thorough and informative, The Mitotic Spindle: Methods and Protocols, is a valuable resource for researchers who are new to mitosis or are already experts in the field.

These roles are not mutually exclusive.
