Target Information
Protein p21 is a tumor suppressor protein that inhibits Cyclin-dependent kinases (CDK) and is transcriptionally activated by p53. It plays a key role in the cellular response to genotoxic stress and is a major transcriptional target of p53. Nuclear p21 binds and inhibits CDK1 and CDK2, blocking cell cycle progression from G1 to S phase or G2 to mitosis after DNA damage, allowing DNA repair. In the cytoplasm, p21 has anti-apoptotic activity by inhibiting caspase 3 and the apoptotic kinases ASK1 and JNK. It exhibits dual roles in carcinogenesis, functioning both as a tumor suppressor and as an oncogene depending on context.
