NFKBID
Nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor, delta also known as IκBNS is a protein in humans that is encoded by the NFKBID gene. IκBNS is a member of the atypical inhibitors of NF-κB (also called the nuclear IκBs). NF-κB is a transcription factor, which regulates the expression of its target genes, depending on intracellular and extracellular signals. As NFKBID influences the impact of NF-κB on several genes, it is involved in cellular responses to stimuli such as stress and bacterial or viral antigens. == Structure ==
NFKBID is a nuclear protein with 327 amino acids. It contains six ankyrin repeats (ANKs), that are surrounded by a nuclear localization signal sequence (NLS) at the N-terminus and a short C-terminus. The ANKs are characteristic for all IκB proteins. The NLS is an additional characteristic structural element of only atypical IκB proteins, which is responsible for the localization of the protein into the nucleus. In contrast, classical inhibitors, e.g. IκBα and IκBβ, are located in the cytoplasm. A high resolution structure of NFKBID is not available yet.
