Target data Acts as a negative regulator of entry into mitosis (G2 to M transition) by protecting the nucleus from cytoplasmically activated cyclin B1-complexed CDK1 before the onset of mitosis by mediating phosphorylation of CDK1 on 'Tyr-15' (PubMed : 15070733, PubMed : 7743995, PubMed : 8348613, PubMed : 8428596). Specifically phosphorylates and inactivates cyclin B1-complexed CDK1 reaching a maximum during G2 phase and a minimum as cells enter M phase (PubMed : 7743995, PubMed : 8348613, PubMed : 8428596). Phosphorylation of cyclin B1-CDK1 occurs exclusively on 'Tyr-15' and phosphorylation of monomeric CDK1 does not occur (PubMed : 7743995, PubMed : 8348613, PubMed : 8428596). Its activity increases during S and G2 phases and decreases at M phase when it is hyperphosphorylated (PubMed : 7743995). A correlated decrease in protein level occurs at M/G1 phase, probably due to its degradation (PubMed : 7743995). See full target information WEE1
