Immunopharmacology Comments
IKKε is the only inducible IKK family member. Expression is induced in response to LPS, viral infection and several cytokines. IKKε expression is restricted to pancreas, thymus, spleen and peripheral blood leukocytes. This is in contrast to all other IKK family kinases which are constitutively and ubiquitously expressed.

General Comments
IKKε and TBK1 phosphorylate the transcription factors interferon (IFN) regulator factor (IRF) 3 and 7. This function is critical for the induction of the type I IFN response (induction of IFN genes and IFN-stimulated genes) in response to microbial infection [4,11].
