Summation

SFN (14-3-3-sigma) dimer binds the complex of CCNB1 (cyclin B1) and CDK1 (Cdc2) in the cytosol and prevents the translocation of the CCNB1:CDK1 complex into the nucleus. This induces G2 cell cycle arrest as nuclear localization of the CCNB1:CDK1 complex is necessary for phosphorylation of nuclear target proteins that are needed for the G2/M transition (Chan et al. 1999).
