C0167954 - A family of inhibitory proteins which bind to the REL PROTO-ONCOGENE PROTEINS and modulate their activity. In the CYTOPLASM, I-kappa B proteins bind to the transcription factor NF-KAPPA B. Cell stimulation causes its dissociation and translocation of active NF-kappa B to the nucleus. 1/10

NCI Thesaurus A7600119 AT224193762 A family of proteins that bind to the nuclear localization signal (NLS) domains of the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappaB) transcription factor complexes. This sequesters NF-kappaB in the cytoplasm and prevents its binding to the activation domains of target genes in the nucleus. Phosphorylation of I kappa B proteins, which is catalyzed by cytokine-activated I kappa B kinases (IKBK; IKK), disrupts binding to NF-kappaB and induces the degradation of I kappa B; this allows NF-kappaB to enter the nucleus and activate the transcription of target genes.
