NFKBIB

Gene
Nfkbib
Protein
NF-kappa-B inhibitor beta
Organism
Mus musculus
Length
359 amino acids
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.
Similarity
Belongs to the NF-kappa-B inhibitor family.
