Outline of Final Research Achievements

In this study, first we identified the consensus sequence of the novel phosphorylation motif (non-S/TP motif) of Cdk1 and clarified the relationship between Cdk1 phosphorylations of the non-S/TP motif and the classical S/TP motif. Furthermore, we showed the binding of multiple M phase kinases to the S/TP motif and also the mode of the bindings. Moreover, we demonstrated the concerted regulation of the M phase by binding of the multiple M phase kinases to the S/TP motif. Thus, our study showed the molecular basis of the mechanism by which Cdk1 functions as the master M phase kinase.
