Rabbit Anti-Human I-Kappa-B-Kinase Beta (IKKβ) recognizes an epitope near the C-terminus of Human IKKβ. This polyclonal antibody was purified using affinity chromatography.
Nuclear factor κ B (NF-κB) is a ubiquitous transcription factor and an essential mediator of gene expression during activation of immune and inflammatory responses. NF-κB mediates the expression of a great variety of genes in response to extracellular stimuli including IL-1, TNFα, and bacteria product LPS. NF-κB is associated with IκB proteins in the cell cytoplasm, which inhibit NF-κB activity. The long-sought IκB kinase (IKK), which phosphorylates IκB, and mediates IκB degradation and NF-κB activation, was recently identified by several laboratories.1-4 IKK is a serine protein kinase, and the IKK complex contains α and β subunits (IKKα and IKKβ). IKKα and IKKβ interact with each other and both are essential for NF-κB activation. IKKβ phosphorylates both IκB-α and IκB-β. IKKβ is expressed in variety of human tissues.
