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 acts as a major transcriptional target of p53.
In the nucleus, p21 binds and inhibits CDK1 and CDK2, blocking the transition from G1 to S phase or G2 to mitosis after DNA damage, allowing DNA repair.
In the cytoplasm, p21 exhibits anti-apoptotic activity by binding to and inhibiting caspase 3, ASK1, and JNK. Thus, p21 has dual roles in carcinogenesis, functioning both as a tumor suppressor and an oncogene depending on context.
