Divergent polo box domains underpin the unique kinetoplastid kinetochore [PDF]
Kinetochores are macromolecular machines that drive eukaryotic chromosome segregation by interacting with centromeric DNA and spindle microtubules. While most eukaryotes possess conventional kinetochore proteins, evolutionarily distant kinetoplastid ...

Kinetochore-bound Mps1 regulates kinetochore–microtubule attachments via Ndc80 phosphorylation [PDF]
Dividing cells detect and correct erroneous kinetochore–microtubule attachments during mitosis, thereby avoiding chromosome missegregation. The Aurora B kinase phosphorylates microtubule-binding elements specifically at incorrectly attached kinetochores, promoting their release and providing another chance for proper attachments to form.

In many eukaryotes, the centromere is epigenetically specified and not strictly defined by sequence. In contrast, budding yeast has a specific 125 bp sequence required for kinetochore function.

The RZZ complex requires the N-terminus of KNL1 to mediate optimal Mad1 kinetochore localization in human cells [PDF]
The spindle assembly checkpoint is a surveillance mechanism that blocks anaphase onset until all chromosomes are properly attached to microtubules of the mitotic spindle.

Calcium depletion destabilises kinetochore fibres by the removal of CENP-F from the kinetochore
The attachment of spindle fibres to the kinetochore is an important process that ensures successful completion of the cell division. The Ca2+ concentration increases during the mitotic phase and contributes microtubule stability. However, its role in the

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

Synergistic Control of Kinetochore Protein Levels by Psh1 and Ubr2.
The accurate segregation of chromosomes during cell division is achieved by attachment of chromosomes to the mitotic spindle via the kinetochore, a large multi-protein complex that assembles on centromeres.

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

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 ...

Summary: This protocol measures the 3D Euclidean distance (Δ3D) between two/three fluorescently labeled kinetochore components in fixed samples using Kinetochore Delta software (KiDv1.0.1, MATLAB based).
