Recent advances in plant kinetochore research [PDF]
Faithful chromosome segregation is crucial for cell division in eukaryotes, facilitated by the kinetochore, a multi-subunit protein complex that connects chromosomes to the spindle microtubules.

Quantitative Analysis of Kinetochore Protein Levels and Inter-Kinetochore Distances in Mammalian Cells During Mitosis [PDF]
The mammalian kinetochore is a multi-layered protein complex that forms on the centromeric chromatin. The kinetochore serves as the attachment hub for the plus ends of microtubules emanating from the centrosomes during mitosis.

Meiosis-specific distal cohesion site decoupled from the kinetochore [PDF]
Primary constriction of the M-phase chromosome serves as a marker for the kinetochore position. Underlying this observation is the concept that the kinetochore is spatially linked with the pericentromere where sister-chromatids are cohered. Here, we find

Integrating Functions at the Kinetochore [PDF]
Kinetochore components have catalytic as well as structural activities. New evidence illustrates how these proteins integrate spindle morphogenesis with regulation of the timing and accuracy of chromosome segregation.

Kinetochore structure: electron spectroscopic imaging of the kinetochore. [PDF]
The structure of the kinetochore in thin section has been studied in the Indian muntjac by an electron spectroscopic imaging technique. This procedures allows the analysis of the distribution of phosphorus within the layers of the kinetochore. The results indicate that this element is a major component of both the inner and outer plates whereas it is ...

Tension Management in the Kinetochore [PDF]
The kinetochore is the protein machine built at the centromere that integrates mechanical force and chemical energy from dynamic microtubules into directed chromosome motion. The kinetochore also provides a powerful signaling function that is able to alter the properties of the spindle checkpoint and initiate a signal transduction cascade that leads to

Structural plasticity of the living kinetochore [PDF]
The kinetochore is a large, evolutionarily conserved protein structure that connects chromosomes with microtubules. During chromosome segregation, outer kinetochore components track depolymerizing ends of microtubules to facilitate the separation of ...

The spindle assembly checkpoint (SAC) prevents anaphase onset in response to chromosome attachment defects, and SAC silencing is essential for anaphase onset. Following anaphase onset, activated Cdc14 phosphatase dephosphorylates the substrates of cyclin-

DNA content of a functioning chicken kinetochore [PDF]
© The Author(s) 2014. In order to understand the three-dimensional structure of the functional kinetochore in vertebrates, we require a complete list and stoichiometry for the protein components of the kinetochore, which can be provided by genetic and ...

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
