Feedback control of chromosome separation by a midzone Aurora B gradient.
Porto, Portugal. In Science, Aug 2014
A midzone-associated Aurora B gradient was found to monitor chromosome position along the division axis and to prevent premature chromosome decondensation by retaining Condensin I. PP1/PP2A phosphatases counteracted this gradient and promoted chromosome decondensation and NER.
Making an effective switch at the kinetochore by phosphorylation and dephosphorylation.
New York City, United States. In Chromosoma, Jun 2013
Erroneous microtubule attachment is destabilized by Aurora B-mediated phosphorylation of multiple microtubule-binding protein complexes at the kinetochore, such as the KMN network proteins and the Ska/Dam1 complex, while Plk-dependent phosphorylation of BubR1 stabilizes kinetochore-microtubule attachment by recruiting PP2A-B56.
Aurora at the pole and equator: overlapping functions of Aurora kinases in the mitotic spindle.
Brighton, United Kingdom. In Open Biol, Mar 2013
In most eukaryotes, ranging from amoebas to humans, Aurora activity appears to be required both at the spindle pole and the kinetochore, and these activities are often split between two different Aurora paralogues, termed Aurora A and B. Polar and equatorial functions of Aurora kinases have generally been considered separately, with Aurora A being mostly involved in centrosome dynamics, whereas Aurora B coordinates kinetochore attachment and cytokinesis.
