Kinetochore protein depletion underlies cytokinesis failure and somatic polyploidization in the moss Physcomitrella patens

open access: yeseLife, 2019
Lagging chromosome is a hallmark of aneuploidy arising from errors in the kinetochore–spindle attachment in animal cells. However, kinetochore components and cellular phenotypes associated with kinetochore dysfunction are much less explored in plants ...

Ybp2 associates with the central kinetochore of Saccharomyces cerevisiae and mediates proper mitotic progression. [PDF]

open access: yesPLoS ONE, 2008
The spindle checkpoint ensures the accurate segregation of chromosomes by monitoring the status of kinetochore attachment to microtubules. Simultaneous mutations in one of several kinetochore and cohesion genes and a spindle checkpoint gene cause a ...

Compare and contrast the reaction coordinate diagrams for chemical reactions and cytoskeletal force generators. [PDF]

open access: yes, 2013
Reaction coordinate diagrams are used to relate the free energy changes that occur during the progress of chemical processes to the rate and equilibrium constants of the process.

Exploring Plant Meiosis: Insights from the Kinetochore Perspective

open access: yesCurrent 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.

Chromosome segregation in plant meiosis [PDF]

open access: yes, 2014
Faithful chromosome segregation in meiosis is essential for ploidy stability over sexual life cycles. In plants, defective chromosome segregation caused by gene mutations or other factors leads to the formation of unbalanced or unreduced gametes creating

Molecular basis of outer kinetochore assembly on CENP-T

open access: yeseLife, 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).

Identification of four unconventional kinetoplastid kinetochore proteins KKT22–25 in Trypanosoma brucei [PDF]

open access: yesOpen Biology, 2019
The kinetochore is a multi-protein complex that drives chromosome segregation in eukaryotes. It assembles onto centromere DNA and interacts with spindle microtubules during mitosis and meiosis. Although most eukaryotes have canonical kinetochore proteins,

Kinetochore structure: electron spectroscopic imaging of the kinetochore. [PDF]

open access: yesThe Journal of cell biology, 1989
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 ...

A comparison of the distribution of actin and tubulin in the mammalian mitotic spindle as seen by indirect immunofluorescence [PDF]

open access: yes, 1977
Rabbit antibodies against actin and tubulin were used in an indirect immunofluorescence study of the structure of the mitotic spindle of PtK1 cells after lysis under conditions that preserve anaphase chromosome movement. During early prophase there is no

Plasmodium Condensin Core Subunits SMC2/SMC4 Mediate Atypical Mitosis and Are Essential for Parasite Proliferation and Transmission [PDF]

open access: yes, 2020
Condensin is a multi-subunit protein complex regulating chromosome condensation and segregation during cell division. In Plasmodium spp., the causative agent of malaria, cell division is atypical and the role of condensin is unclear.
