    text
  • localizes at interphase centrosomes, where it accumulates following DNA damage or spindle poisons
  • basic FUNCTION
  • involved in the regulation of gene transcription and cell proliferation
  • inhibiting the RB growth-suppressing function by interfering with RB-mediated HDAC1 recruitment on E2F target gene promoters
  • acting as HDAC1 competitor (by displacing HDAC1 from the CDKN1A promoter) and its down-regulation is involved in colon carcinoma cell proliferation
  • contributing to the maintenance of the G2/M checkpoint induced by DNA damage
  • transcriptionally activates AKT1 gene through STAT3, which sustains KT1 activation and promotes cell survival
  • RNA polymerase II binding protein involved in the regulation of gene transcription and, in response to DNA damage, promotes TP53 transcription
  • important role in survival of cells expressing mutant TP53
  • nucleolar stress sensor, which is required as a cofactor for JUN-mediated apoptosis
  • activating XIAP expression in response to DNA damage
  • plays an important role in DNA damage response (DDR) and its contribution seems to be relevant for the spindle assembly checkpoint
  • involved in transcriptional regulation, cell cycle control, DNA damage responses and in the execution of cell death programs
  • RNA polymerase II-binding protein that is involved in the regulation of gene transcription, which undergoes stabilization and accumulation in response to DNA damage
  • important role in the cellular response to DNA damage
  • CELLULAR PROCESS cell life, proliferation/growth

    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • hyperphosphorylated during the G1/S phase transition
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • DLK/ZIP kinase, MAP3K12 (induced apoptosis)
  • interacting with TSG101(functioning as cooperative coactivators in androgen receptor-mediated transcription)
  • critical regulator of the cellular outcome of the TP53 response
  • nucleolar stress sensor, which is required as a cofactor for JUN-mediated apoptosis
  • binding to PAWR, POLR2J, RB1/RB, RBL1/P107, RBL2/P130, SP1 and MAPT
  • interacts directly with nuclear hormone receptors to enhance their transactivation
  • HIPK2, a proapoptotic kinase, is involved in AATF degradation (HIPK2 interacts with AATF and, upon genotoxic stress, phosphorylates it at specific residues)
  • TP53/AATF interaction results in preferential transactivation of growth arrest TP53 target genes over its pro-apoptotic target genes
