Phosphorylation of Sli15 by Ipl1 is important for proper CPC localization and chromosome stability in Saccharomyces cerevisiae [PDF]
The chromosomal passenger complex (CPC) is a key regulator of eukaryotic cell division, consisting of the protein kinase Aurora B/Ipl1 in association with its activator (INCENP/Sli15) and two additional proteins (Survivin/Bir1 and Borealin/Nbl1). Here we

The mitotic spindle checkpoint [PDF]
Fantastic progress has been made in understanding the spindle checkpoint, the guardian of balanced chromosome segregation. However, several basic questions and many details remain to be worked out. In the meantime, the use of chimeric fluorescent proteins and ever better imaging technology has enhanced the stunning videos of mitosis made today ...

Co-silencing of human Bub3 and dynein highlights an antagonistic relationship in regulating kinetochore-microtubule attachments [PDF]
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.

Oxidative Stress Overrides the Spindle Checkpoint [PDF]
Aneuploidy, an abnormal chromosome set, can ensue from failure of the spindle checkpoint, the safeguard mechanism that halts anaphase onset until mitotic spindle assembly. Inefficiency of cells to maintain the normal chromosome set across cell generations has been linked to tumorigenesis and senescence.

The Spindle Assembly Checkpoint Is Required for Hematopoietic Progenitor Cell Engraftment
Summary: The spindle assembly checkpoint plays a pivotal role in preventing aneuploidy and transformation. Many studies demonstrate impairment of this checkpoint in cancer cells.

Chromosome segregation in plant meiosis [PDF]
Faithful chromosome segregation in meiosis is essential for ploidy stability over sexual life cycles. In plants, defective chromosome segregation caused by gene mutations or other factors leads to the formation of unbalanced or unreduced gametes creating

CENP-F stabilizes kinetochore-microtubule attachments and limits dynein stripping of corona cargoes [PDF]
Accurate chromosome segregation demands efficient capture of microtubules by kinetochores and their conversion to stable bioriented attachments that can congress and then segregate chromosomes.

Loss of function of the Cik1/Kar3 motor complex results in chromosomes with syntelic attachment that are sensed by the tension checkpoint. [PDF]
The attachment of sister kinetochores by microtubules emanating from opposite spindle poles establishes chromosome bipolar attachment, which generates tension on chromosomes and is essential for sister-chromatid segregation.

HIPK2 and extrachromosomal histone H2B are separately recruited by Aurora-B for cytokinesis [PDF]
Cytokinesis, the final phase of cell division, is necessary to form two distinct daughter cells with correct distribution of genomic and cytoplasmic materials.
