Protein

Inhibitor of nuclear factor kappa-B kinase subunit alpha

Gene

CHUK

Organism
Gallus gallus (Chicken)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

Phosphorylates inhibitors of NF-kappa-B thus leading to the dissociation of the inhibitor/NF-kappa-B complex and ultimately the degradation of the inhibitor. Phosphorylates 'Ser-10' of histone H3 at NF-kappa-B-regulated promoters during inflammatory responses triggered by cytokines.By similarity

Catalytic activityi

ATP + [I-kappa-B protein] = ADP + [I-kappa-B phosphoprotein].

Enzyme regulationi

Activated when phosphorylated and inactivated when dephosphorylated.By similarity
