Mitotic entry is triggered by the Cyclin B-Cdk1 kinase, which phosphorylates numer-ous substrates. The accumulation of these phosphorylated substrates relies on inhib-iting the opposing PP2A-B55 phosphatase. With its asynchronous cell divisions, the C. elegans embryo is an attractive model for disse...
