Background Information

IRF2, also known as IFN regulatory factor 2, which belongs to the IRF family. IRF2 specifically binds to the upstream regulatory region of type I IFN and IFN-inducible MHC class I genes (the IFN consensus sequence (ICS)) and represses those genes. IRF2 also acts as an activator for several genes including H4 and IL7. IRF2 constitutively binds to the ISRE promoter to activate IL7. IRF2 is involved in cell cycle regulation through binding the site II (HiNF-M) promoter region of H4 and activating transcription during cell growth. The calculated molecular weight of IRF2 is 39 kDa, but post-modification of IRF2 is about 50 kDa (PMID: 17698501).
