The inhibitor of kB kinase (IKK) is a central regulator of NF-kB signalling. Here the authors identify a motif conserved in substrates of canonical and alternative NF-kB pathways which mediates docking to catalytic IKK dimers: they show that phosphorylation of the conserved tyrosine suppresses the docking interaction.
