Phosphorylated, ubiquitinated IkB is degraded by the proteasome (Miyamoto et al. 1994, Traenckner et al. 1994, Alkalay et al. 1995, DiDonato et al. 1995, Li et al. 1995, Lin et al. 1995, Scherer et al. 1995, Chen et al. 1995). IkB does not dissociate from NF-kB before it is proteolyzed (Miyamoto et al. 1994, Traenckner et al. 1994, DiDonato et al. 1995, Lin et al. 1995).
