Quizplus · Accepted Answer

The tumor suppressor protein p53 activates the synthesis of p21, a cyclin-dependent kinase (Cdk) inhibitor, which stops the cell cycle at the G1 checkpoint to allow for DNA repair or apoptosis if damage cannot be repaired. This prevents damaged cells from replicating and potentially becoming cancerous. p53 does not inhibit phosphodiesterase, stimulate cell cycle progression, or phosphorylate Cdk on an inhibitory site.
