Dual-specific autophosphorylation of kinase IKK2 enables phosphorylation of substrate IκBα through a phosphoenzyme intermediate
{{output}}
Rapid and high-fidelity phosphorylation of serine residues at positions 32 and 36 of IκBα by IKK2/β, a highly conserved prototypical Ser/Thr kinase in vertebrates, is critical for canonical NF-κB activation. Here, we report that human IKK2 not only phospho... ...
