eLife, 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 ...

Length-dependent anisotropic scaling of spindle shape [PDF]
, 2014 Spindle length varies dramatically across species and during early development to segregate chromosomes optimally. Both intrinsic factors, such as regulatory molecules, and extrinsic factors, such as cytoplasmic volume, determine spindle length scaling ...

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

Exploring Plant Meiosis: Insights from the Kinetochore Perspective
Current 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.

A TOGgle for Tension at Kinetochores [PDF]
Cell, 2016 Differential stability of kinetochore-microtubule attachments at low versus high tension is critical for accurate chromosome segregation. Miller et al. find that a TOG domain microtubule-binding protein imparts intrinsic tension selectivity to kinetochore-microtubule attachments.

Regulation of chromosome congression : focus on the function of hSpindly and the kinetochore recruitment of the Ska complex [PDF]
, 2011 Mitosis is a process in which cells divide their genetic materials equally into two daughter cells. During mitosis, specialized structures called kinetochores (KTs), located at the centromeric regions of chromosomes, are captured by microtubules (MTs ...

Molecular basis of outer kinetochore assembly on CENP-T
eLife, 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).

Balancing the kinetochore ledger [PDF]
Journal of Cell Biology, 2012 Reduction of polo-like kinase-1 (Plk1) at kinetochores as cells progress from prometaphase to metaphase is surprising given that the kinase is thought to stabilize kinetochore–microtubule (kt–MT) attachments. In this issue, Liu et al. (2012. J. Cell Biol.

Bub3p facilitates spindle checkpoint silencing in fission yeast [PDF]
, 2009 Although critical for spindle checkpoint signaling, the role kinetochores play in anaphase promoting complex (APC) inhibition remains unclear. Here we show that spindle checkpoint proteins are severely depleted from unattached kinetochores in fission ...

C-Terminal Motifs of the MTW1 Complex Cooperatively Stabilize Outer Kinetochore Assembly in Budding Yeast [PDF]
, 2020 Kinetochores are macromolecular protein assemblies at centromeres that mediate accurate chromosome segregation during cell division. The outer kinetochore KNL1SPC105, MIS12MTW1, and NDC80NDC80 complexes assemble the KMN network, which harbors the sites ...
