Nuclear factor kappa B (NF-kB) is a ubiquitous transcription factor and an essential mediator of gene expression during activation of immune and inflammatory responses. NF-kB mediates the expression of a great variety of genes in response to extracellular stimuli. NF-kB is associated with IkB proteins in the cell cytoplasm, which inhibit NF-kB activity. IkB is phosphorylated by IkB kinase(IKK) complex that contains IKKa, IKKb, and IKKg. A novel molecule in the IKK complex was recently identified and designated IKKe/IKK-i. IKKe is required for the activation of NF-kB by PMA and T cell receptors but not by TNFa and IL-1. IKKe/IKK-i message is expressed in a variety of tissues and is inducible by TNFa, IL-1, and LPS.
