Therefore we investigated the modifications imposed on NF-kappa B /I kappa B components following stimulation and show that the final step of NF-kappa B induction in vivo involves phosphorylation of several members of the NF-kappa B /I kappa B protein families .
 ( protein: NF-kappa B /I kappa B components, None) , ( protein: NF-kappa B, None) , ( protein: NF-kappa B, None) , ( protein: NF-kappa B, None) , ( protein: NF-kappa B /I kappa B protein families, None)
