The condensin complex is required for proper spindle assembly and chromosome segregation in Xenopus egg extracts. [PDF]

open access: yes, 2003
Chromosome condensation is required for the physical resolution and segregation of sister chromatids during cell division, but the precise role of higher order chromatin structure in mitotic chromosome functions is unclear.

Sad1 Spatiotemporally Regulates Kinetochore Clustering To Ensure High-Fidelity Chromosome Segregation in the Human Fungal Pathogen Cryptococcus neoformans

open access: yesmSphere, 2018
Kinetochore clustering, frequently observed in yeasts, plays a key role in genome organization and chromosome segregation. In the absence of the metaphase plate arrangement, kinetochore clustering in yeast species is believed to facilitate timely ...

The Drosophila histone variant H2A.V works in concert with HP1 to promote kinetochore-driven microtubule formation [PDF]

open access: yes, 2015
Unlike other organisms that have evolved distinct H2A variants for different functions, Drosophila melanogaster has just one variant which is capable of filling many roles.

Establishment of the vertebrate kinetochores [PDF]

open access: yesChromosome Research, 2012
The centromere is essential for accurate chromosome segregation during mitosis and meiosis to achieve transmission of genetic information to daughter cells. To facilitate accurate chromosome segregation, the centromere serves several specific functions, including microtubule binding, spindle-checkpoint control, and sister chromatid cohesion.

The Saccharomyces cerevisiae kinetochore [PDF]

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.

AI-Assisted Forward Modeling of Biological Structures

open access: yesFrontiers in Cell and Developmental Biology, 2019
The rise of machine learning and deep learning technologies have allowed researchers to automate image classification. We describe a method that incorporates automated image classification and principal component analysis to evaluate computational models

Keeping kinetochores on track

open access: yesEuropean Journal of Cell Biology, 2012
The multiple functions of kinetochores are reflected in their complex composition, with over a hundred different proteins, which self-associate in several functional subcomplexes. Most of these kinetochore proteins were identified over the last 10-12 years using a combination of genetic, cell biological, biochemical, and bioinformatic approaches in ...

Reconstruction of the kinetochore: a prelude to meiosis [PDF]

open access: yesCell Division, 2007
Abstract In eukaryotic organisms, chromosomes are spatially organized within the nucleus. Such nuclear architecture provides a physical framework for the genetic activities of chromosomes, and changes its functional organization as the cell moves through the phases of the cell cycle.

BUB-1 promotes amphitelic chromosome biorientation via multiple activities at the kinetochore

open access: yeseLife, 2018
Accurate chromosome segregation relies on bioriented amphitelic attachments of chromosomes to microtubules of the mitotic spindle, in which sister chromatids are connected to opposite spindle poles.

Loss of APC induces polyploidy as a result of a combination of defects in mitosis and apoptosis [PDF]

open access: yes, 2007
Mutations in the adenomatous polyposis coli (APC) tumor suppressor gene initiate a majority of colorectal cancers. Acquisition of chromosomal instability is an early event in these tumors.
