Molecular basis of outer kinetochore assembly on CENP-T

eLife, 2016
Stable kinetochore-microtubule attachment is essential for cell division. It requires recruitment of outer kinetochore microtubule binders by centromere proteins C and T (CENP-C and CENP-T).

Exploring Plant Meiosis: Insights from the Kinetochore Perspective

Current Issues in Molecular Biology, 2023
The central player for chromosome segregation in both mitosis and meiosis is the macromolecular kinetochore structure, which is assembled by >100 structural and regulatory proteins on centromere DNA.

Recruitment of the Ulp2 protease to the inner kinetochore prevents its hyper-sumoylation to ensure accurate chromosome segregation.

PLoS Genetics, 2019
The kinetochore is the central molecular machine that drives chromosome segregation in all eukaryotes. Genetic studies have suggested that protein sumoylation plays a role in regulating the inner kinetochore; however, the mechanism remains elusive. Here,

Human kinetochores are swivel joints that mediate microtubule attachments

eLife, 2016
Chromosome segregation is a mechanical process that requires assembly of the mitotic spindle – a dynamic microtubule-based force-generating machine.

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.

A Rho for the kinetochore

The Journal of Cell Biology, 2004
![Graphic][1] Chromosome alignment on the spindle (top) is lost if Cdc42 is inactivated (bottom). Narumiya/Macmillan Results from Shingo Yasuda, Shuh Narumiya (Kyoto University, Kyoto, Japan), and colleagues reveal microtubules at the cell cortex, are also needed for microtubule–

Chromosome biorientation produces hundreds of piconewtons at a metazoan kinetochore

Nature Communications, 2016
Chromosomes bind microtubules (MT) from opposite spindle poles and the generated tension stabilizes kinetochore-MT attachments. Here the authors measure kinetochore forces by engineering two force sensors and propose that kinetochore fibers exert ...

CENP-meta, an essential kinetochore kinesin required for the maintenance of metaphase chromosome alignment in Drosophila. [PDF]

, 2000
CENP-meta has been identified as an essential, kinesin-like motor protein in Drosophila. The 257-kD CENP-meta protein is most similar to the vertebrate kinetochore-associated kinesin-like protein CENP-E, and like CENP-E, is shown to be a component of ...

Prime movers : mechanochemistry of mitotic kinesins [PDF]

, 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.

Recent Progress on the Localization of the Spindle Assembly Checkpoint Machinery to Kinetochores

Cells, 2019
Faithful chromosome segregation during mitosis is crucial for maintaining genome stability. The spindle assembly checkpoint (SAC) is a surveillance mechanism that ensures accurate mitotic progression.
