The microtubule catastrophe promoter Sentin delays stable kinetochore-microtubule attachment in oocytes

The critical step in meiosis is to attach homologous chromosomes to the opposite poles. In mouse oocytes, stable microtubule end-on attachments to kinetochores are not established until hours after spindle assembly, and phosphorylation of kinetochore proteins by Aurora B/C is responsible for the del...
