Also found in: Acronyms
NFKBIB A gene on chromosome 19q13.1 that encodes an I-kappa-B protein that inhibits the multimeric NFKB complex by trapping it in the cytoplasm. Kinases IKBKA or IKBKB phosphorylate NFKBIA’s serine residues, marking them for destruction via the ubiquination pathway, allowing activation of the NFKB complex which, once activated, translocates to the nucleus, binds DNA and activates transcription.
