Related Product Information for anti-IkappaB-beta antibody

The NF-kappaB/Rel transcription factors are present in the cytosol in an inactive state complexed with the inhibitory IkappaB proteins. Activation occurs via phosphorylation of IkappaBalpha at Ser32 and Ser36 followed by proteasome-mediated degradation that results in the release and nuclear translocation of active NF-kappaB. IkappaBalpha 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 IkappaB at these activating sites have been identified. The regulation of IkappaBbeta and IkappaBepsilon is similar to that of IkappaBalpha. However, the phosphorylation and ubiquitin-mediated degradation of these proteins occurs with much slower kinetics. IKK phosphorylation of IkappaBbeta occurs at Ser19 and Ser23, while IkappaBepsilon can be phosphorylated at Ser18 and Ser22.

NCBI Description

The protein encoded by this gene belongs to the NF-kappa-B inhibitor family, which inhibit NF-kappa-B by complexing with, and trapping it in the cytoplasm. Phosphorylation of serine residues on these proteins by kinases marks them for destruction via the ubiquitination pathway, thereby allowing activation of the NF-kappa-B, which translocates to the nucleus to function as a transcription factor. Alternatively spliced transcript variants have been found for this gene.[provided by RefSeq, Jul 2011]

Uniprot Description

IkB-beta: a protein of the NF-kappa-B inhibitor family. 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 IKBA- dependent inactivation. Association with inhibitor kappa B- interacting Ras-like proteins 1 and 2 may also explain the slower degradation. Interacts with ligand-binding domain of thyroid hormone receptor-beta, inhibitor kappa B-interacting Ras-like protein 1, inhibitor kappa B-interacting protein Ras2, p65 (RELA) and c-Rel. Expressed in all tissues examined.
