A Molecular View of Kinetochore Assembly and Function
Biology, 2017 Kinetochores are large protein assemblies that connect chromosomes to microtubules of the mitotic and meiotic spindles in order to distribute the replicated genome from a mother cell to its daughters.

Cold Spring Harbor Perspectives in Biology, 2014 A critical requirement for mitosis is the distribution of genetic material to the two daughter cells. The central player in this process is the macromolecular kinetochore structure, which binds to both chromosomal DNA and spindle microtubule polymers to direct chromosome alignment and segregation. This review will discuss the key kinetochore activities

The path of DNA in the kinetochore [PDF]
Current Biology, 2006 The kinetochore is the protein-DNA complex at eukaryotic centromeres that functions as the attachment site for spindle microtubules. In budding yeast, the centromere spans 120 bp, there is a single microtubule per kinetochore, and the entire spindle is composed of 16 kinetochore microtubules plus four interpolar microtubules from each pole.

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.

Modeling Dual Pathways for the Metazoan Spindle Assembly Checkpoint [PDF]
, 2006 Using computational modelling, we investigate mechanisms of signal transduction focusing on the spindle assembly checkpoint where a single unattached kinetochore is able to signal to prevent cell cycle progression.

Structure of the inner kinetochore CCAN complex assembled onto a centromeric nucleosome
Nature, 2019 In eukaryotes, accurate chromosome segregation in mitosis and meiosis maintains genome stability and prevents aneuploidy. Kinetochores are large protein complexes that, by assembling onto specialized Cenp-A nucleosomes1,2, function to connect centromeric

Reductionism at the vertebrate kinetochore [PDF]
Journal of Cell Biology, 2012 The kinetochore forms the site of attachment for mitotic spindle microtubules driving chromosome segregation. The interdependent protein interactions in this large structure have made it difficult to dissect the function of its components. In this issue, Hori et al. (2013. J. Cell Biol.

Co-silencing of human Bub3 and dynein highlights an antagonistic relationship in regulating kinetochore-microtubule attachments [PDF]
, 2015 We previously reported that the spindle assembly checkpoint protein Bub3 is involved in regulating kinetochore-microtubule (KT-MT) attachments. Also, Bub3 was reported to interact with the microtubule motor protein dynein.

Checkpoint proteins come under scrutiny [PDF]
, 2013 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 ...

Cell Reports, 2014 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.
