NFKBIE (NF-Kappa-B Inhibitor Epsilon): NFKBIE is a gene that encodes a key regulator of the NF-kappa-B pathway, which plays a vital role in immune responses, inflammation, and cell survival. It functions by inhibiting NF-kappa-B activity, thereby controlling the expression of genes involved in immune and inflammatory processes. Dysregulation of NFKBIE has been linked to autoimmune diseases, chronic inflammation, and cancer, highlighting its role in immune regulation and disease progression.
