Bub1 kinase in the regulation of mitosis

Animal Cells and Systems, 2021
Accurate chromosome segregation is required for cell survival and organismal development. During mitosis, the spindle assembly checkpoint acts as a safeguard to maintain the high fidelity of mitotic chromosome segregation by monitoring the attachment of ...

Evolutionary cell biology of chromosome segregation: insights from trypanosomes [PDF]

Open Biology, 2013
Faithful transmission of genetic material is essential for the survival of all organisms. Eukaryotic chromosome segregation is driven by the kinetochore that assembles onto centromeric DNA to capture spindle microtubules and govern the movement of ...

Structural basis of Stu2 recruitment to yeast kinetochores

eLife, 2021
Chromosome segregation during cell division requires engagement of kinetochores of sister chromatids with microtubules emanating from opposite poles. As the corresponding microtubules shorten, these ‘bioriented’ sister kinetochores experience tension ...

CENP-F stabilizes kinetochore-microtubule attachments and limits dynein stripping of corona cargoes [PDF]

, 2020
Accurate chromosome segregation demands efficient capture of microtubules by kinetochores and their conversion to stable bioriented attachments that can congress and then segregate chromosomes.

chTOG is a conserved mitotic error correction factor

eLife, 2020
Accurate chromosome segregation requires kinetochores on duplicated chromatids to biorient by attaching to dynamic microtubules from opposite spindle poles, which exerts forces to bring kinetochores under tension.

TRIP13PCH-2 promotes Mad2 localization to unattached kinetochores in the spindle checkpoint response. [PDF]

, 2015
The spindle checkpoint acts during cell division to prevent aneuploidy, a hallmark of cancer. During checkpoint activation, Mad1 recruits Mad2 to kinetochores to generate a signal that delays anaphase onset.

Visualizing kinetochore architecture [PDF]

Current Opinion in Structural Biology, 2011
Kinetochores are large macromolecular assemblies that link chromosomes to spindle microtubules (MTs) during mitosis. Here we review recent advances in the study of core MT-binding kinetochore complexes using electron microcopy methods in vitro and nanometer-accuracy fluorescence microscopy in vivo.

Mammalian kinetochores count attached microtubules in a sensitive and switch-like manner. [PDF]

, 2019
The spindle assembly checkpoint (SAC) prevents anaphase until all kinetochores attach to the spindle. Each mammalian kinetochore binds many microtubules, but how many attached microtubules are required to turn off the checkpoint, and how the kinetochore ...

The Kinetochore [PDF]

Cold Spring Harbor Perspectives in Biology, 2014
A critical requirement for mitosis is the distribution of genetic material to the two daughter cells. The central player in this process is the macromolecular kinetochore structure, which binds to both chromosomal DNA and spindle microtubule polymers to direct chromosome alignment and segregation. This review will discuss the key kinetochore activities

Chromosome Segregation Is Biased by Kinetochore Size [PDF]

, 2018
Chromosome missegregation during mitosis or meiosis is a hallmark of cancer and the main cause of prenatal death in humans. The gain or loss of specific chromosomes is thought to be random, with cell viability being essentially determined by selection ...
