Anti-IkappaBNS antibodies enable researchers to detect and measure the IkappaBNS antigen in biological samples. This target is a reported synonym of the NFKBID gene, which encodes NFKB inhibitor delta. This protein is known to function in inflammatory response pathways and the regulation of gene expression, among other biological roles. The human version of IkappaBNS has a canonical amino acid length of 313 residues and a protein mass of 33.5 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus of cells. IkappaBNS is a member of the NF-kappa-B inhibitor protein family.
