Target Information
Protein p21 is a tumor suppressor protein that inhibits cyclin-dependent kinases (CDK) and is transcriptionally activated by p53.
p21 plays an essential role in the cellular response to genotoxic stress and is a major transcriptional target of p53.
In the nucleus, p21 binds and inhibits CDK1 and CDK2, blocking the G1/S and G2/M transitions after DNA damage to allow repair.
In the cytoplasm, p21 exhibits anti-apoptotic activity by binding and inhibiting caspase 3, ASK1, and JNK.
This dual function contributes to both tumor suppression and oncogenic processes depending on cellular context.
