IKBKB (10A2) Antibody

IKBKB (Inhibitor of kappa light polypeptide gene enhancer in B-cells kinase beta, also called IKK2/IKKB) is a member of the IKK comple, Xenopus/Amphibian, which is composed of IKK-alpha, IKK-beta, IKK-gamma and IKAP. Phosphorylation of I-Kappa-B on a serine residue by the IKK comple, Xenopus/Amphibian, frees NF-kB from I-Kappa-B and marks it for degradation via ubiquination. IKK-beta has been shown to activate NF-kB and phosphorylate IKB-alpha and beta. Phosphorylation of 2 sites at the activation loop of IKK-beta is essential for activation of IKK by TNF and IL1. Once activated, IKK-beta is autophosphorylated which in turn decreases IKK activity and prevents prolonged activation of the inflammatory response. Additionally, IKK-beta activity can also be regulated by MEKK-1.
