Post Translational Modifications | Phosphorylated by RPS6KA1.followed by degradation. Interaction with NKIRAS1 and NKIRAS2 probably prevents phosphorylation. |
Function | Inhibits NF-kappa-B by complexing with and trapping it in the cytoplasm. However, the unphosphorylated form resynthesized after cell stimulation is able to bind NF-kappa-B allowing its transport to the nucleus and protecting it to further NFKBIA-dependent inactivation. Association with inhibitor kappa B-interacting NKIRAS1 and NKIRAS2 prevent its phosphorylation rendering it more resistant to degradation, explaining its slower degradation. |
