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.

The kinetochore–microtubule interface at a glance

open access: yesJournal of Cell Science, 2018
Accurate chromosome segregation critically depends on the formation of attachments between microtubule polymers and each sister chromatid. The kinetochore is the macromolecular complex that assembles at the centromere of each chromosome during mitosis ...

Not just a by‐product: circular DNA molecules derived from V(D)J recombination are linked to worse prognosis in B‐cell leukemia

open access: yesMolecular Oncology, EarlyView.
Gao et al. report that circular DNA molecules created as by‐products of V(D)J recombination during lymphocyte maturation (ESCs) can replicate and be retained for much longer than previously thought in healthy cells. In BCP‐ALL cells, increased ESC abundance correlates with a greater chance of relapse likely mediated by their ability to induce genome ...

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,

Kinetochore to order

open access: yesThe Journal of Cell Biology, 2006
![][1] Overproduced CENP-A (green) induces an ectopic kinetochore (blue) with attached microtubule (red). KARPEN/ELSEVIER Extra functional kinetochores can be created by overexpressing just a single protein, according to Patrick Heun, Sylvia Erhardt, Gary Karpen (University ...

Human Shugoshin Mediates Kinetochore-Driven Formation of Kinetochore Microtubules [PDF]

open access: yesCell Cycle, 2006
The conserved protein Shugoshin (Sgo) plays a role in the maintenance of centromeric cohesion in mitosis and meiosis. Human Shugoshin (hSgo) was first identified as an overexpressed protein in breast cancers. Here we demonstrate that hSgo mediates kinetochore-driven formation of kinetochore -microtubules (MTs) during bipolar spindle assembly.

Survivin and Aurora Kinase A control cell fate decisions during mitosis

open access: yesMolecular Oncology, EarlyView.
Aurora A interacts with survivin during mitosis and regulates its centromeric role. Loss of Aurora A activity mislocalises survivin, the CPC and BubR1, leading to disruption of the spindle checkpoint and triggering premature mitotic exit, which we refer to as ‘mitotic slippage’.

Quantitative Analysis of Kinetochore Protein Levels and Inter-Kinetochore Distances in Mammalian Cells During Mitosis

open access: yesBio-Protocol
The mammalian kinetochore is a multi-layered protein complex that forms on the centromeric chromatin. The kinetochore serves as the attachment hub for the plus ends of microtubules emanating from the centrosomes during mitosis.

Recent Progress on the Localization of the Spindle Assembly Checkpoint Machinery to Kinetochores

open access: yesCells, 2019
Faithful chromosome segregation during mitosis is crucial for maintaining genome stability. The spindle assembly checkpoint (SAC) is a surveillance mechanism that ensures accurate mitotic progression.

Measuring NDC80 binding reveals the molecular basis of tension-dependent kinetochore-microtubule attachments

open access: yesbioRxiv, 2018
Proper kinetochore-microtubule attachments, mediated by the NDC80 complex, are required for error-free chromosome segregation. Erroneous attachments are corrected by the tension dependence of kinetochore-microtubule interactions.
