Target

  • Function
    Inhibits translation initiation and cap-dependent translation. May excert its function by hindering the interaction between EIF4A1 and EIF4G. Inhibits the helicase activity of EIF4A. Modulates the activation of JUN kinase. Down-regulates the expression of MAP4K1, thus inhibiting events important in driving invasion, namely, MAPK85 activation and consequent JUN-dependent transcription. May play a role in apoptosis. Tumor suppressor. Inhibits tumor promoter-induced neoplastic transformation. Binds RNA.
  • Tissue specificity
    Up-regulated in proliferative cells. Highly expressed in epithelial cells of the mammary gland. Reduced expression in lung cancer and colon carcinoma.
  • Sequence similarities
    Belongs to the PDCD4 family.
    Contains 2 MI domains.
  • Domain
    Binds EIF4A1 via both MI domains.
  • Post-translational
    modifications
    Polyubiquitinated, leading to its proteasomal degradation. Rapidly degraded in response to mitogens. Phosphorylation of the phosphodegron promotes interaction with BTRC and proteasomal degradation.
  • Cellular localization
    Nucleus. Cytoplasm. Shuttles between the nucleus and cytoplasm. Predominantly nuclear under normal growth conditions, and when phosphorylated at Ser-457. Exported from the nucleus in the absence of serum.

  • Lane 1: Wild-type HAP1 whole cell lysate (20 µg)
    Lane 2: PDCD4 knockout HAP1 whole cell lysate (20 µg)
    Lane 3: HeLa whole cell lysate (20 µg)
    Lane 4: HEK293 whole cell lysate (20 µg)

    Lanes 1 - 4: Merged signal (red and green). Green - ab80590 observed at 52 kDa. Red - loading control, ab9484, observed at 37 kDa.

    ab80590 was shown to specifically react with PDCD4 in wild-type HAP1 cells as signal was lost in PDCD4 knockout cells. Wild-type and PDCD4 knockout samples were subjected to SDS-PAGE. ab80590 and ab9484 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 20000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
