Monopolin subunit Csm1 associates with MIND complex to establish monopolar attachment of sister kinetochores at meiosis I [PDF]

open access: yes, 2013
Sexually reproducing organisms halve their cellular ploidy during gametogenesis by undergoing a specialized form of cell division known as meiosis. During meiosis, a single round of DNA replication is followed by two rounds of nuclear divisions (referred

Structural plasticity of the living kinetochore [PDF]

open access: yes, 2017
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 ...

DNA content of a functioning chicken kinetochore [PDF]

open access: yes, 2014
© 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 ...

Chromosome Segregation Is Biased by Kinetochore Size [PDF]

open access: yes, 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 ...

Kinetochore alignment within the metaphase plate is regulated by centromere stiffness and microtubule depolymerases [PDF]

open access: yes, 2010
During mitosis in most eukaryotic cells, chromosomes align and form a metaphase plate halfway between the spindle poles, about which they exhibit oscillatory movement. These movements are accompanied by changes in the distance between sister kinetochores,

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

open access: yes, 2010
Sds22 defines protein phosphatase 1 location and function at kinetochores and subsequent activity of aurora B in ...

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.

The RZZ complex requires the N-terminus of KNL1 to mediate optimal Mad1 kinetochore localization in human cells [PDF]

open access: yesOpen Biology, 2015
The spindle assembly checkpoint is a surveillance mechanism that blocks anaphase onset until all chromosomes are properly attached to microtubules of the mitotic spindle.

Modeling Dual Pathways for the Metazoan Spindle Assembly Checkpoint [PDF]

open access: yes, 2006
Using computational modelling, we investigate mechanisms of signal transduction focusing on the spindle assembly checkpoint where a single unattached kinetochore is able to signal to prevent cell cycle progression.

Divergent polo box domains underpin the unique kinetoplastid kinetochore [PDF]

open access: yesOpen Biology, 2016
Kinetochores are macromolecular machines that drive eukaryotic chromosome segregation by interacting with centromeric DNA and spindle microtubules. While most eukaryotes possess conventional kinetochore proteins, evolutionarily distant kinetoplastid ...
