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.

Latrunculin A delays anaphase onset in fission yeast by disrupting an ase1-independent pathway controlling mitotic spindle stability [PDF]

open access: yes, 2008
It has been proposed previously that latrunculin A, an inhibitor of actin polymerization, delays the onset of anaphase by causing spindle misorientation in fission yeast.

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).

TRIP13PCH-2 promotes Mad2 localization to unattached kinetochores in the spindle checkpoint response. [PDF]

open access: yes, 2015
The spindle checkpoint acts during cell division to prevent aneuploidy, a hallmark of cancer. During checkpoint activation, Mad1 recruits Mad2 to kinetochores to generate a signal that delays anaphase onset.

Recruitment of the Ulp2 protease to the inner kinetochore prevents its hyper-sumoylation to ensure accurate chromosome segregation.

open access: yesPLoS Genetics, 2019
The kinetochore is the central molecular machine that drives chromosome segregation in all eukaryotes. Genetic studies have suggested that protein sumoylation plays a role in regulating the inner kinetochore; however, the mechanism remains elusive. Here,

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,

Possible role of human ribonuclease dicer in the regulation of R loops

open access: yesFEBS Open Bio, EarlyView.
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

Mammalian kinetochores count attached microtubules in a sensitive and switch-like manner. [PDF]

open access: yes, 2019
The spindle assembly checkpoint (SAC) prevents anaphase until all kinetochores attach to the spindle. Each mammalian kinetochore binds many microtubules, but how many attached microtubules are required to turn off the checkpoint, and how the kinetochore ...

Development of a personalized visualization and analysis tool to improve clinical care in complex multisystem diseases with application to scleroderma

open access: yesArthritis Care &Research, Accepted Article.
Background In complex diseases, it is challenging to assess a patient's disease state, trajectory, treatment exposures, and risk of multiple outcomes simultaneously, efficiently and at the point of care. Methods We developed an interactive patient‐level data visualization and analysis tool (VAT) that automates illustration of a scleroderma patient's ...

Human kinetochores are swivel joints that mediate microtubule attachments

open access: yeseLife, 2016
Chromosome segregation is a mechanical process that requires assembly of the mitotic spindle – a dynamic microtubule-based force-generating machine.
