The kinetochore, a multi-protein complex assembled on centromeres, is essential to segregate chromosomes during cell division. Deficiencies in kinetochore function can lead to chromosomal instability and aneuploidy-a hallmark of cancer cells. Kinetochore

CENP-A Is Dispensable for Mitotic Centromere Function after Initial Centromere/Kinetochore Assembly [PDF]
Human centromeres are defined by chromatin containing the histone H3 variant CENP-A assembled onto repetitive alphoid DNA sequences. By inducing rapid, complete degradation of endogenous CENP-A, we now demonstrate that once the first steps of centromere ...

A TOGgle for Tension at Kinetochores [PDF]
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.

Budding yeast kinetochore proteins, Chl4 and Ctf19, are required to maintain SPB-centromere proximity during G1 and late anaphase. [PDF]
In the budding yeast, centromeres stay clustered near the spindle pole bodies (SPBs) through most of the cell cycle. This SPB-centromere proximity requires microtubules and functional kinetochores, which are protein complexes formed on the centromeres ...

Spatiotemporal dynamics of Spc105 regulates the assembly of the Drosophila kinetochore [PDF]
The formation of kinetochores shortly before each cell division is a prerequisite for proper chromosome segregation. The synchronous mitoses of Drosophila syncytial embryos have provided an ideal in vivo system to follow kinetochore assembly kinetics and

Checkpoint proteins come under scrutiny [PDF]
Details are emerging of the interactions between the kinetochore and various spindle checkpoint proteins that ensure that sister chromatids are equally divided between daughter cells during cell ...

Visualizing kinetochore architecture [PDF]
Kinetochores are large macromolecular assemblies that link chromosomes to spindle microtubules (MTs) during mitosis. Here we review recent advances in the study of core MT-binding kinetochore complexes using electron microcopy methods in vitro and nanometer-accuracy fluorescence microscopy in vivo.

Bod1, a novel kinetochore protein required for chromosome biorientation [PDF]
We have combined the proteomic analysis of Xenopus laevis in vitro–assembled chromosomes with RNA interference and live cell imaging in HeLa cells to identify novel factors required for proper chromosome segregation. The first of these is Bod1, a protein
