Schematic structures of nuclear factor of κ‐light chain of enhancer‐activated B cells (NF‐κB) superfamily and the inhibitor of NF‐κB (IκB) family. The schematic structures of NF‐κB subfamily proteins, Rel subfamily proteins, and IκB family proteins (cytoplasmic IκB proteins and nuclear IκB proteins) are shown. ARD, ankyrin repeat domain; GRR, glycine‐rich region; NLS, nuclear localization sequence; RHD, Rel homology domain; TAD, transactivation domain
