Description: During the eukaryotic cell cycle, activation of Cdc2 (Cdk1) kinase regulates the transition into M-phase. Cdc2 forms a complex with cyclin B, and activation of this complex is controlled by dephosphorylation of Cdc2 at tyrosine 15 and threonine 14. Phosphorylation at Tyr15 and is carried out by Wee1 and Myt1 protein kinases, while Tyr15 dephosphorylation is carried out by the cdc25 phosphatase.
