May regulate the expression of IL-2, IL-6, and other cytokines through regulation on NF-kappa-B activity. Functions in the regulation of inflammatory responses. May also regulate TCR-induced negative selection of thymocytes.I-kappa-BNS, the nuclear I-kappa-B-like protein encoded by Nfkbid, is required for the development of marginal zone and peritoneal B-1 B cells and additionally required for extrafollicular antibody responses to T-independent and -dependent immunogens.I-kappa-BNS has been identified as a member of the I-kappa-B family of NF-kappa-B inhibitors, which undergoes induction upon TCR signaling. I-kappa-BNS mediates both positive and negative gene regulation, depending on individual cell type and/or cytokine.
