Protocol Available protocols: Western Blotting, Immunohistochemistry (Paraffin), Flow Cytometry (Fixed/Permeabilized) Specificity / Sensitivity Phospho-IKK alpha/beta (Ser176/180) (16A6) Rabbit Monoclonal Antibody detects IKKα only when phosphorylated at Ser176/180 and IKKβ only when phosphorylated at Ser177/181. Species Reactivity: Human, Mouse, Rat, Hamster, Monkey Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser176/180 of human IKKα. Background The NF-κB/Rel transcription factors are present in the cytosol in an inactive state, complexed with the inhibitory IκB proteins (1-3). Most agents that activate NF-κB do so through a common pathway based on phosphorylation-induced, proteasome-mediated degradation of IκB (3-7). The key regulatory step in this pathway involves activation of a high molecular weight IκB kinase (IKK) complex whose catalysis is generally carried out by three tightly associated IKK subunits. IKKα and IKKβ serve as the catalytic subunits of the kinase and IKKγ serves as the regulatory subunit (8,9). Activation of IKK depends upon phosphorylation at Ser177 and Ser181 in the activation loop of IKKβ (Ser176 and Ser180 in IKKα), which causes conformational changes, resulting in kinase activation (10-13).
