Background

  • Function

    P21 plays an important role in controlling cell cycle progression and DNA damage-induced G2 arrest. Involved in p53/TP53 mediated inhibition of cellular proliferation in response to DNA damage. Also involved in p53-independent DNA damage-induced G2 arrest mediated by CREB3L1 in astrocytes and osteoblasts. Binds to and inhibits cyclin-dependent kinase activity, preventing phosphorylation of critical cyclin-dependent kinase substrates and blocking cell cycle progression. Functions in the nuclear localization and assembly of cyclin D-CDK4 complex and promotes its kinase activity towards RB1. At higher stoichiometric ratios, inhibits the kinase activity of the cyclin D-CDK4 complex. Inhibits DNA synthesis by DNA polymerase delta by competing with POLD3 for PCNA binding. Negatively regulates the CDK4- and CDK6-driven phosphorylation of RB1 in keratinocytes, thereby resulting in the release of E2F1 and subsequent transcription of E2F1-driven G1/S phase promoting genes[1][2].

  • Subcellular Localization

    Cytoplasm; Nucleus

  • Expression


    Tissue_specificity:It is expressed in all adult tissues, but the expression level in the brain is 5 times lower.

    Induction:Activated by p53/TP53, mezerein (antileukemic compound) and IFNB1. Repressed by HDAC1

  • Subunit

    Interacts with HDAC1; the interaction is prevented by competitive binding of C10orf90/FATS to HDAC1 facilitating acetylation and protein stabilization of CDKN1A/p21 (By similarity). Interacts with MKRN1 (PubMed:19536131). Interacts with PSMA3 (PubMed:11350925). Interacts with PCNA (PubMed:11595739, PubMed:18703516, PubMed:18794347, PubMed:8861913). Component of the ternary complex, cyclin D-CDK4-CDKN1A. Interacts (via its N-terminal domain) with CDK4; the interaction promotes the assembly of the cyclin D-CDK4 complex, its nuclear translocation and promotes the cyclin D-dependent enzyme activity of CDK4 (PubMed:9106657). Binding to CDK2 leads to CDK2/cyclin E inactivation at the G1-S phase DNA damage checkpoint, thereby arresting cells at the G1-S transition during DNA repair (PubMed:19445729). Interacts with PIM1 (PubMed:12431783). Interacts with STK11 and NUAK1 (PubMed:25329316). Interacts wih DTL (PubMed:23213251). Interacts with isoform 1 and isoform 2 of TRIM39 (PubMed:23213251). Interacts with PKP3; the interaction sequesters CDKN1A to the cytoplasm thereby repressing its role as an inhibitor of CDK4- and CDK6-driven RB1 phosphorylation (By similarity)
