Activation occurs via phosphorylation of IκBα at Ser32 and Ser36 followed by proteasome-mediated degradation that results in the release and nuclear translocation of active NF-κB (3-7). IκBα phosphorylation and resulting Rel-dependent transcription are activated by a highly diverse group of extracellular signals including inflammatory cytokines, growth factors, and chemokines. Kinases that phosphorylate IκB at these activating sites have been identified (8). The regulation of IκBβ and IκBε is similar to that of IκBα. However, the phosphorylation and ubiquitin-mediated degradation of these proteins occurs with much slower kinetics (9). IKK phosphorylation of IκBβ occurs at Ser19 and Ser23, while IκBε can be phosphorylated at Ser18 and Ser22 (10).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nI-kappa-B-beta; IkappaBbeta; IkB-B; IkB-beta; IKBB; NF-kappa-B inhibitor beta; NF-kappa-BIB; NFKB inhibitor beta; NFKBIB; nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor, beta; Thyroid receptor-interacting protein 9; TR-interacting protein 9; TRIP-9; TRIP9\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 48\nSource\/Isotype: Mouse IgG1","brand":"CST","offers":[{"title":"Default Title","offer_id":46799960113321,"sku":"8635T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-8635t","provider":"Iright","version":"1.0","type":"link"}
