Application Abreviews Notes
IP 1/30 - 1/50.
IHC-P 1/50.
WB 1/10000 - 1/50000. Detects a band of approximately 24 kDa (predicted molecular weight: 24 kDa).


  • Function

    Physiological suppressor of IKK-epsilon and TBK1 that plays an inhibitory role in virus- and TLR3-triggered IRF3. Inhibits TLR3-mediated activation of interferon-stimulated response elements (ISRE) and the IFN-beta promoter. May act by disrupting the interactions of IKBKE or TBK1 with TICAM1/TRIF, IRF3 and DDX58/RIG-I. Does not inhibit NF-kappa-B activation pathways.
  • Tissue specificity

    Widely expressed. Expressed in brain, heart, skeletal muscle, colon, thymus, spleen, kidney, liver, small intestine, placenta, lung and leukocytes. Present in all cell lines tested (at protein level).
  • Sequence similarities

    Belongs to the SIKE family.
  • Post-translational

    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localization

  • Lane 1: Wild-type HAP1 cell lysate (20 µg)
    Lane 2: SIKE1 knockout HAP1 cell lysate (20 µg)
    Lane 3: HeLa cell lysate (20 µg)
    Lane 4: PC3 cell lysate (20 µg)
    Lanes 1 - 4: Merged signal (red and green). Green - ab183509 observed at 25 kDa. Red - loading control, ab8245, observed at 37 kDa.

    ab183509 was shown to specifically react with SIKE1 when SIKE1 knockout samples were used. Wild-type and SIKE1 knockout samples were subjected to SDS-PAGE. ab183509 and ab8245 (loading control to GAPDH) were both diluted 1/10 000 and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

    Lane 1 : SH-SY5Y cell lysate
    Lane 2 : Hela cell lysate
    Lane 3 : 293 cell lysate

    Lysates/proteins at 20 µg per lane.

    All lanes : Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated at 1/1000 dilution

    Predicted band size: 24 kDa
    Additional bands at: 24 kDa. We are unsure as to the identity of these extra bands.

  • Immunohistochemical analysis of paraffin embedded Human kidney tissue labeling SIKE1 with ab183509 at 1/50.

  • Lysate from 293 cells was immunoprecipitated with ab183509 at a 1/50 dilution. For the subsequent blot, ab183509 used at a 1/10000 dilution with an anti-Rabbit IgG (HRP), specific to the non-reduced form of IgG at a 1/1500 dilution for the secondary. Blocking/ Dilution buffer: 5% NFDM/TBST. Lane 2: TBS instead of lysate.
