Description: The LK2NAP monoclonal antibody reacts with mouse IkB zeta (INAP, MAIL). IkBz is a member of the IkB family of cytoplasmic proteins and transcription factors and also shares structural homology with Bcl-3. It is induced in monocytes, macrophages and B cells in response to TLR and IL-1R signaling. In NK cells, IkBz is rapidly upregulated in response to IL-12 and IL-18 and is necessary for production of IFN gamma. In T cells, IkBz is not necessary for IFN gamma and IL-4 production by Th1 and Th2 cells, respectively. However in Th17 cells, IkBz acts in concert with RORa and RORgt to upregulate IL-17A, IL-17F, IL-21, IL-22 and IL-23R expression.
