Embryonic fibroblast cells from TBK1-deficient mice show decreased IRF3 activation and IFN induction by poly IC, while IKKi-deficient cells show normal IRF3 activation. However, residual activation of IRF3 in TBK1-deficient cells is totally abolished in TBK1 and IKKi double-deficient cells, indicating that the functions of TBK1 and IKKi are redundant in fibroblast cells.[Hemmi et al 2004].

It was also reported that IKKi directly phophorylates signal transducer and activator of transcription 1 (STAT1) [Tenoever et al 2007].

Chicken IKKi shows 68% and 62% identity to the human IKKi and human TBK1 respectively.
