Antagonistic activities of CDC14B and CDK1 on USP9X regulate WT1-dependent mitotic transcription and survival

Abstract

In yeast, the phosphatase Cdc14 controls mitotic exit. Here the authors show that mammalian CDC14B antagonizes CDK1, to keep the deubiquitinase USP9X unphosphorylated and inactive, and that Wilms’ tumor protein 1 is a substrate for active USP9X that directs mitosis-specific transcription to regulate mitotic survival.
