Invitrogen™ Human IKK epsilon (aa 573-708) Control Fragment Recombinant Protein

IKBKE is an activator of nuclear factor-kappa-B. Over expression of IKBKE has been observed in breast cancer cells, and suppression of IKBKE induces cell death. NF-kappa-B is a ubiquitous transcription factor and an essential mediator of gene expression during activation of immune and inflammatory responses. NF-kappa-B mediates the expression of a great variety of genes in response to extracellular stimuli. NF-kappa-B is associated with Ikappa-B proteins in the cell cytoplasm, which inhibit NF-kappa-B activity. Ikappa-B is phosphorylated by Ikappa-B kinase (IKK) complex that contains IKK-a, IKK-b, and IKK-gamma. A novel molecule in the IKK complex was recently identified and designated IKK-iota/IKK-i. IKK epsilon is required for the activation of NF-kappa-B by PMA and T cell receptors but not by TNF-a and IL-1. IKK-iota/IKK-i message is expressed in a variety of tissues and is inducible by TNF-a, IL-1, and LPS.
