Sensing centromere tension: Aurora B and the regulation of kinetochore function

Open access
Lampson, Michael A., Cheeseman, Iain M.·2011·Trends in Cell Biology

Abstract

Maintaining genome integrity during cell division requires regulated interactions between chromosomes and spindle microtubules. To ensure that daughter cells inherit the correct chromosomes, the sister kinetochores must attach to opposite spindle poles. Tension across the centromere stabilizes correct attachments, whereas phosphorylation of kinetochore substrates by the conserved Ipl1/Aurora B kinase selectively eliminates incorrect attachments. Here, we review our current understanding of how mechanical forces acting on the kinetochore are linked to biochemical changes to control chromosome segregation. We discuss models for tension sensing and regulation of kinetochore function downstream of Aurora B, and mechanisms that specify Aurora B localization to the inner centromere and determine its interactions with substrates at distinct locations.

  • A balanced phosphorylation/dephosphorylation system is critical to maintain the fine spatial gradients of Aurora B phosphorylation at the kinetochore, where tension is thought to allow substrate movement into and out of the regions of highest Aurora B kinase activity.

    “This type of balanced phosphorylation/dephosphorylation system is going to be critical to maintain the fine spatial gradients of Aurora B phosphorylation at the kinetochore, wherein tension is thought to allow substrate movement into and out of the regions of highest Aurora B kinase activity [59].”

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.
