Although Cyclin B1 and Cdk1 are known to bind with high affinity our results reveal that in living cells there is a pool of Cyclin B1 that is not bound to Cdk1 Furthermore we provide evidence that the affinity of Cyclin B1 for Cdk1 increases during the cell cycle indicating that the assembly of the complex is a regulated step

the existence of a pool of Cyclin B1 not bound to Cdk1 FCS and FCCS measurements reveal that the fraction of Cyclin B1 bound to Cdk1 increases as cells progress through G2 phase and this is explained by an increase in the affinity of binding We conclude that the binding between Cyclin B1 and Cdk1 is cell cycle regulated Overall our results

1 Introduction Cell cycle control relies on the rapid formation and disassembly of regulatory protein complexes At the core of the cell cycle machinery is the family of cyclindependent kinases Cdks reviewed in whose members are activated by binding a cyclin subunitCyclin B1 binds and activates Cdk1 to form the major mitotic kinase that is required for cells to enter mitosis
