WebCyclin E. Cyclin E is the limiting factor for G1 phase progression and S phase entry. The cyclin E gene is a target of E2Fs, and the protein associates with Cdk2 and activates its … Cyclin E is a member of the cyclin family. Cyclin E binds to G1 phase Cdk2, which is required for the transition from G1 to S phase of the cell cycle that determines initiation of DNA duplication. The Cyclin E/CDK2 complex phosphorylates p27 (an inhibitor of Cyclin D), tagging it for degradation, thus promoting expression of Cyclin A, allowing progression to S …
