Fission yeast bub1 is a mitotic centromere protein essential for the spindle checkpoint and the preservation of correct ploidy through mitosis [PDF]
The spindle checkpoint ensures proper chromosome segregation by delaying anaphase until all chromosomes are correctly attached to the mitotic spindle.

Bub1 is a fission yeast kinetochore scaffold protein, and is sufficient to recruit other spindle checkpoint proteins to ectopic sites on chromosomes [PDF]
The spindle checkpoint delays anaphase onset until all chromosomes have attached in a bi-polar manner to the mitotic spindle. Mad and Bub proteins are recruited to unattached kinetochores, and generate diffusible anaphase inhibitors.

New mitotic regulators released from chromatin
Faithful action of the mitotic spindle segregates duplicated chromosomes into daughter cells. Perturbations of this process result in chromosome mis-segregation, leading to chromosomal instability and cancer development.

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 ...

Bub1 kinase in the regulation of mitosis
Accurate chromosome segregation is required for cell survival and organismal development. During mitosis, the spindle assembly checkpoint acts as a safeguard to maintain the high fidelity of mitotic chromosome segregation by monitoring the attachment of ...

Spindle assembly checkpoint silencing and beyond [PDF]
The Spindle Assembly Checkpoint (SAC) prevents anaphase onset in the absence of kinetochore-microtubule attachment, ensuring that cells with unattached kinetochores do not proceed into anaphase.

On the regulation of chromosome segregation in human cells : implications of Bub1 Kinase inhibition during cell division [PDF]
The maintenance of correct chromosome number (euploidy) during cell division is essential for health. Loss of euploidy is observed in most cancers and is linked to tumorigenesis.

Tubulin dimers concentrate within an ER spindle envelope because cytoplasmic organelles outside the envelope occupy significant volume. In many animal species, the oocyte meiotic spindle, which is required for chromosome segregation, forms without ...

The requirements for oocyte meiotic cytokinesis during polar body extrusion are not well understood. In particular, the relationship between the oocyte meiotic spindle and polar body contractile ring dynamics remains largely unknown.
