Kinetochore Localization of Murine Bub1 Is Required for Normal Mitotic Timing and Checkpoint Response to Spindle Damage
Open accessAbstract
The mitotic checkpoint ensures proper chromosome segregation by delaying anaphase until chromosomes are aligned on the spindle. Following prolonged spindle damage, however, cells eventually exit mitosis and undergo apoptosis. We show here that a murine homolog of the yeast mitotic checkpoint gene BUB1 localizes to the kinetochore during mitosis. By expressing a dominant-negative mutant, we show that mBub1 is not only required for the checkpoint response to spindle damage, but acts in the timing of a normal mitosis. In addition, when mBub1 function is compromised, cells escape apoptosis and continue cell cycle progression, despite leaving mitosis with a disrupted spindle. These data demonstrate a role for kinetochore-associated mBub1 in regulating exit from mitosis, and suggest functional links between the mitotic checkpoint and subsequent apoptotic events in G1.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
