UniProtKB - Q8NI38 (IKBD_HUMAN)
Protein
NF-kappa-B inhibitor delta
Gene
NFKBID
Organism
Homo sapiens (Human)
Status
Functioni
Regulates the expression of IL-2, IL-6, and other cytokines through regulation on NF-kappa-B activity. Functions in the regulation of inflammatory responses. Involved in the induction of T helper 17 cells (Th17) differentiation upon recognition of antigen by T cell antigen receptor (TCR). May also regulate TCR-induced negative selection of thymocytes.By similarity
