WebCyclins and cyclin-dependent kinases control when cells divide, making them important targets for cancer therapy. Cyclin A (green) and cyclin-dependent kinase 2 (blue) with ATP (magenta). Division of cells is tightly regulated, and for very good reason. During early development of an embryo, many cells divide and multiply. 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.
