The Drosophila histone variant H2A.V works in concert with HP1 to promote kinetochore-driven microtubule formation [PDF]
, 2015 Unlike other organisms that have evolved distinct H2A variants for different functions, Drosophila melanogaster has just one variant which is capable of filling many roles.

Bub1 kinase targets Sgo1 to ensure efficient chromosome biorientation in budding yeast mitosis. [PDF]
PLoS Genetics, 2007 During cell division all chromosomes must be segregated accurately to each daughter cell. Errors in this process give rise to aneuploidy, which leads to birth defects and is implicated in cancer progression.

The kinesin Eg5 inhibitor K858 induces apoptosis but also survivin-related chemoresistance in breast cancer cells [PDF]
, 2016 Inhibitors of kinesin spindle protein Eg5 are characterized by pronounced antitumor activity. Our group has recently synthesized and screened a library of 1,3,4-thiadiazoline analogues with the pharmacophoric structure of K858, an Eg5 inhibitor.

Mad3 KEN boxes mediate both Cdc20 and Mad3 turnover, and are critical for the spindle checkpoint. [PDF]
PLoS ONE, 2007 Mitotic progression is controlled by proteolytic destruction of securin and cyclin. The mitotic E3 ubiquitin ligase, known as the anaphase promoting complex or cyclosome (APC/C), in partnership with its activators Cdc20p and Cdh1p, targets these proteins

A new survivin tracer tracks, delocalizes and captures endogenous survivin at different subcellular locations and in distinct organelles [PDF]
, 2016 Survivin, the smallest member of the inhibitor of apoptosis protein family, plays a central role during mitosis and exerts a cytoprotective function. Survivin is highly expressed in most cancer types and contributes to multiple facets of carcinogenesis ...

Attachment and tension in the spindle assembly checkpoint [PDF]
Journal of Cell Science, 2002 Faithful transmission of chromosomes during mitosis is ensured by the spindle assembly checkpoint. This molecular safeguard examines whether prerequisites for chromosome segregation have been satisfied and thereby determines whether to execute or to delay chromosome segregation.

Precocious activation of APC/C-Cdh1 at pre-anaphase causes genome instability [PDF]
, 2008 Faithful chromosome segregation and thereby accurate gene transmission are crucial for all organisms. Until proper attachment of the mitotic spindle to the kinetochore is established, the ubiquitin ligase (E3) Cdc20-activated APC/C (anaphase promoting ...

Regulation of AURORA B function by mitotic checkpoint protein MAD2 [PDF]
, 2016 Cell cycle checkpoint signaling stringently regulates chromosome segregation during cell division. MAD2 is one of the key components of the spindle and mitotic checkpoint complex that regulates the fidelity of cell division along with MAD1, CDC20, BUBR1,

Neoplasia: An International Journal for Oncology Research, 2008 CHFR is an E3 ubiquitin ligase and an early mitotic checkpoint protein implicated in many cancers and in the maintenance of genomic stability. To analyze the role of CHFR in genomic stability, by siRNA, we decreased its expression in genomically stable ...

Precocious centriole disengagement and centrosome fragmentation induced by mitotic delay
Nature Communications, 2017 The spindle assembly checkpoint delays mitotic progression until sister chromatids are bi-oriented. Here the authors show that moderate delays in mitotic progression induce centrosome fragmentation and centriole disengagement and that spindle bipolarity ...
