The mitotic exit network
What is it? The mitotic exit network – commonly known by the acronym MEN — is a signal transduction cascade which triggers the exit of mitosis. The MEN has been characterized in the budding yeast Saccharomyces cerevisiae, and the protein names below refer to components from this species, though many are conserved in vertebrates. The main switch of this cascade is the small G protein Tem1 and it...

متن کاملProtein Phosphatases Drive Mitotic Exit
Mitosis is the final stage of the cell cycle that results in the formation of two independent daughter cells with an equal and identical complement of chromosomes (Figure 1). This requires a complex series of events such as nuclear envelope breakdown, spindle formation, equal chromosome segregation, packaging of chromosomes into daughter nuclei and constriction of the plasma membrane at the cel...
متن کاملMitotic exit in two dimensions.
Metaphase of mitosis is brought about in all eukaryotes by activation of cylin-dependent kinase (Cdk1), whereas exit from mitosis requires down-regulation of Cdk1 activity and dephosphorylation of its target proteins. In budding yeast, the completion of mitotic exit requires the release and activation of the Cdc14 protein-phosphatase, which is kept inactive in the nucleolus during most of the c...
متن کاملGene expression and mitotic exit induced by microtubule-stabilizing drugs.
To explore the molecular mechanisms underlying the actions of Taxol and the functionally related molecule epothilone B (EpoB), we have analyzed the gene expression profiles in A549 cells in response to increasing concentrations of these microtubule-stabilizing drugs. An almost identical expression pattern was observed in cells treated with either Taxol or EpoB. Low concentrations of the drugs i...
