说明

一般說明

FUNCTION: SwissProt: O14920 # 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. Also phosphorylates NCOA3 (By similarity).
SIZE: 756 amino acids; 86564 Da
SUBUNIT: Preferentially found as a heterodimer with IKK-alpha but also as a homodimer. Directly interacts with IKK-gamma/NEMO and TRPC4AP. The tripartite complex can also bind to MEKK1, MAP3K14/NIK, IKAP and IKB-alpha-p65-p50 complex. Phosphorylated IKB-alpha is further released from the complex. Found in a complex composed of NCOA2, NCOA3, IKKA, IKBKG and CREBBP. Interacts with SQSTM1 through PRKCZ or PRKCI. Forms an NGF-induced complex with IKBKB, PRKCI and TRAF6. May interact with MAVS/IPS1. Interacts with NALP2. Interacts with Yersinia yopJ.
SUBCELLULAR LOCATION: Cytoplasm.
TISSUE SPECIFICITY: Highly expressed in heart, placenta, skeletal muscle, kidney, pancreas, spleen, thymus, prostate, testis and peripheral blood.
PTM: Upon cytokine stimulation, phosphorylated on Ser-177 and Ser- 181 by MEKK1 and/or MAP3K14/NIK; which enhances activity. Once activated, autophosphorylates on the C-terminal serine cluster; which decreases activity and prevents prolonged activation of the inflammatory response. & Yersinia yopJ may acetylate Ser/Thr residues, preventing phosphorylation and activation, which blocks the I-kappa-B signaling pathway.
SIMILARITY: SwissProt: O14920 ## Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. IkappaB kinase subfamily. & Contains 1 protein kinase domain.

品質

Evaluated by Kinase assay: 10 µl of varying amounts of IKKβ was mixed with 5 µl of 1 mg/ml IKKtide synthetic peptide substrate and 5 µl of distilled water. Reaction was initiated by adding 5 µl of 250 µM [33P]-ATP and incubating for 15 min at 30°C followed by spotting the reaction on phosphocellulose paper, fixing in 1% phosphoric acid, and assaying with a scintillation counter.
