Background
p21 (CDKN1A, cyclin-dependent kinase inhibitor 1A) is a broad-spectrum CDK-inhibitor family protein mediating cell-cycle repression, DNA-damage response and senescence control. p21 inhibits multiple Cyclin-CDK assemblies, prevents Rb phosphorylation and arrests cells at G1 and G2 phases to repress DNA replication. As major transcriptional target downstream of p53, p21 is strongly induced upon genotoxic stress to enforce cell-cycle checkpoint. p21 also interacts with PCNA to directly suppress DNA polymerase activity. Beyond tumor-suppression, p21 modulates cell differentiation and stem-cell homeostasis, and exhibits context-dependent dual roles in cancers.
