A model illustrating the regulation of CPC localization in preanaphase and anaphase by Cdk1 and Ipl1/Aurora in yeast. A key to cellular components and states of spindle MT dynamics (red text) is shown. Predominant CPC localization patterns in wild-type cells are indicated as “typical” (yellow background). Other localization patterns are atypical or represent a minor part of the wild-type localization. Arrows indicate balance between Sli15 phosphorylation states. Centromere-localized CPC is not shown. (A) Regulation of CPC localization in preanaphase/metaphase. (B) Regulation of CPC localization in early/mid anaphase B. (C) Regulation of CPC localization in late anaphase B. See Discussion for details.
