IP Use at an assay dependent concentration.


  • FunctionSerine/threonine protein involved in the signaling cascade converging to the activation of the transcription factor NF-kappa-B. May function as an IKK kinase, playing an essential role in the transcription of a subset of TNF-alpha-induced genes. Also mediates production of RANTES/CCL5 and interferon-beta/IFNB1. Has a pivotal role in the innate immune response. Phosphorylates Borna disease virus (BDV) P protein. Phosphorylates and activates IRF3 and IRF7 and allows their nuclear localization. This leads to production of alpha/beta interferons and the development of a cellular antiviral state. It also seems to be a central factor in the induction of the antiviral interferon response. Inhibition of its interaction with IRF3, due to HCV NS3 binding or BDV P protein seems to be one mechanism of inhibition of the innate immune responses of hepatitis C virus (HCV) infection or Borna disease virus infection respectively.

Anti-NAK/TBK1 antibody [108A429] images

  • Predicted band size : 87.5 kDa

    Lane 1: Wild-type HAP1 cell lysate (20 µg)
    Lane 2: NAK knockout HAP1 cell lysate (20 µg)
    Lane 3: HeLa cell lysate (20 µg)
    Lane 4: HepG2 cell lysate (20 µg)
    Lanes 1 - 4: Merged signal (red and green). Green - ab12116 observed at 90 kDa. Red - loading control, ab181602, observed at 37 kDa.
    ab12116 was shown to recognize NAK when NAK knockout samples were used, along with additional cross-reactive bands. Wild-type and NAK knockout samples were subjected to SDS-PAGE. ab12116 and ab181602 (loading control to GAPDH) were diluted at 1 μg/ml and 1/10 000 respectively and incubated overnight at 4°C. Blots were developed with goat anti-rabbit IgG (H + L) and goat anti-mouse IgG (H + L) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.

  • Overlay histogram showing HeLa cells stained with ab12116 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab12116, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells ) used under the same conditions. Acquisition of >5,000 events was performed.
