WebG1 cyclins bind to Cdk proteins during G1. Once bound and activated, the Cdk signals the cell's exit from G1 and entry into S phase. When the cell reaches an appropriate size and the cellular environment is correct for DNA replication, the cyclins begin to degrade. G1 cyclin degradation deactivates the Cdk and leads to entry into S phase.
