Summary: This gene encodes an inhibitor of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappaB). The encoded protein prevents NF-kappaB-mediated transcription activation by sequestering it in the cytosol. In response to signals that induce NF-kappaB, such as cytokines and growth factors, the encoded protein undergoes phosphorylation, triggering its rapid ubiquitination and proteasomal degradation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2015]

CpG-ODN-mediated TLR9 innate immune signalling and calcium dyshomeostasis converge on the NFkappaB inhibitory protein IkappaBbeta to drive IL1alpha and IL1beta expression.
Title: CpG-ODN-mediated TLR9 innate immune signalling and calcium dyshomeostasis converge on the NFκB inhibitory protein IκBβ to drive IL1α and IL1β expression.
IkappaBbeta has essential functions within the Rel-NFkappaB generation module, specifically for the RelA:RelA homodimer, which controls a subset of NFkappaB target genes.

In vivo degradation rate constants were measured for NF-kappaB-bound & -unbound IkappaB. Models suggest differential degradation rates of free & bound IkappaB may be a new cross-regulation mechanism imparting functional robustness to the signaling module.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
