Calcium depletion destabilises kinetochore fibres by the removal of CENP-F from the kinetochore [PDF]

open access: yesScientific Reports, 2017
The attachment of spindle fibres to the kinetochore is an important process that ensures successful completion of the cell division. The Ca2+ concentration increases during the mitotic phase and contributes microtubule stability. However, its role in the

Recent advances in plant kinetochore research [PDF]

open access: yesFrontiers in Cell and Developmental Biology
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.

Plant kinetochore complex: composition, function, and regulation [PDF]

open access: yesFrontiers in Plant Science
The kinetochore complex, an important protein assembly situated on the centromere, plays a pivotal role in chromosome segregation during cell division.

Poleward force at the kinetochore in metaphase depends on the number of kinetochore microtubules. [PDF]

open access: yesThe Journal of cell biology, 1990
To examine the dependence of poleward force at a kinetochore on the number of kinetochore microtubules (kMTs), we altered the normal balance in the number of microtubules at opposing homologous kinetochores in meiosis I grasshopper spermatocytes at metaphase with a focused laser microbeam.

The Saccharomyces cerevisiae kinetochore

open access: yesFEBS Letters, 1996
Accurate chromosome segregation is DApenDAnt on a specialized chromosomal structure, the kinetochore/centromere. The only essential constituent of the S. cerevisiae kinetochore established today is CBF3, a multisubunit complex that binds to S. cerevisiae centromere DNA.

Sds22 regulates aurora B activity and microtubule-kinetochore interactions at mitosis [PDF]

open access: yes, 2010
We have studied Sds22, a conserved regulator of protein phosphatase 1 (PP1) activity, and determined its role in modulating the activity of aurora B kinase and kinetochore-microtubule inter-actions.

Bub1 autophosphorylation feeds back to regulate kinetochore docking and promote localized substrate phosphorylation [PDF]

open access: yes, 2015
During mitosis, Bub1 kinase phosphorylates histone H2A-T120 to promote centromere sister chromatid cohesion through recruitment of shugoshin (Sgo) proteins. The regulation and dynamics of H2A-T120 phosphorylation are poorly understood. Using quantitative

The Kinetochore [PDF]

open access: yesCold 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

Bod1, a novel kinetochore protein required for chromosome biorientation [PDF]

open access: yes, 2007
We have combined the proteomic analysis of Xenopus laevis in vitro–assembled chromosomes with RNA interference and live cell imaging in HeLa cells to identify novel factors required for proper chromosome segregation. The first of these is Bod1, a protein

Step-wise assembly, maturation and dynamic behavior of the human CENP-P/O/R/Q/U kinetochore sub-complex [PDF]

open access: yes, 2012
Kinetochores are multi-protein megadalton assemblies that are required for attachment of microtubules to centromeres and, in turn, the segregation of chromosomes in mitosis. Kinetochore assembly is a cell cycle regulated multi-step process.
