Target Information
Protein p21 is a tumor suppressor protein that inhibits Cyclin-dependent kinases (CDK) and is transcriptionally activated by p53. It plays a crucial role in the cellular response to genotoxic stress and is a major transcriptional target of p53.
In the nucleus, p21 binds to and inhibits Cdk1 and Cdk2, blocking cell cycle transitions (G1 to S phase and G2 to mitosis) after DNA damage, facilitating DNA repair.
In the cytoplasm, p21 exhibits anti-apoptotic activity by inhibiting caspase 3, ASK1, and JNK.
It has dual roles in carcinogenesis—acting both as a tumor suppressor and as an oncogene depending on cellular context.
