Immunol. 187:6456-6462(2011). CC -!- FUNCTION: Key transcriptional regulator of type I interferon (IFN)- CC dependent immune responses and plays a critical role in the innate CC immune response against DNA and RNA viruses (PubMed:27129230, CC PubMed:22095711). Regulates the transcription of type I IFN genes (IFN- CC alpha and IFN-beta) and IFN-stimulated genes (ISG) by binding to an CC interferon-stimulated response element (ISRE) in their promoters. Can CC efficiently activate both the IFN-beta (IFNB) and the IFN-alpha (IFNA) CC genes and mediate their induction via both the virus-activated, MyD88- CC independent pathway and the TLR-activated, MyD88-dependent pathway. CC Induces transcription of ubiquitin hydrolase USP25 mRNA in response to CC lipopolysaccharide (LPS) or viral infection in a type I IFN-dependent CC manner (PubMed:27129230). Required during both the early and late CC phases of the IFN gene induction but is more critical for the late than CC for the early phase. Exists in an inactive form in the cytoplasm of CC uninfected cells and following viral infection, double-stranded RNA CC (dsRNA), or toll-like receptor (TLR) signaling, becomes phosphorylated CC by IKBKE and TBK1 kinases. This induces a conformational change, CC leading to its dimerization and nuclear localization where along with CC other coactivators it can activate transcription of the type I IFN and CC ISG genes. Can also play a role in regulating adaptive immune responses CC by inducing PSMB9/LMP2 expression, either directly or through induction CC of IRF1. Binds to the Q promoter (Qp) of EBV nuclear antigen 1 a CC (EBNA1) and may play a role in the regulation of EBV latency. Can CC activate distinct gene expression programs in macrophages and regulate CC the anti-tumor properties of primary macrophages. CC {ECO:0000269|PubMed:15361868, ECO:0000269|PubMed:15743772, CC ECO:0000269|PubMed:15800576, ECO:0000269|PubMed:18562536, CC ECO:0000269|PubMed:22095711, ECO:0000269|PubMed:27129230}. CC -!- ACTIVITY REGULATION: In the absence of viral infection, maintained as a CC monomer in an autoinhibited state and phosphorylation disrupts this CC autoinhibition leading to the liberation of the DNA-binding and CC dimerization activities and its nuclear localization where it can CC activate type I IFN and ISG genes. CC -!- SUBUNIT: Monomer. Homodimer; phosphorylation-induced. Heterodimer with CC IRF3. Interacts with TICAM1 and TICAM2. Interacts with MYD88 and TRAF6. CC Interacts with NMI; the interaction is direct and leads to the CC inhibition of IRF7-mediated type I IFN production (PubMed:23956435). CC Interacts with GBP4; preventing interaction between TRAF6 and IRF7, CC resulting in impaired TRAF6-mediated IRF7 ubiquitination CC (PubMed:22095711). Interacts with TARBP2; this interaction prevents CC IRF7 phosphorylation and activation (By similarity). CC {ECO:0000250|UniProtKB:Q92985, ECO:0000269|PubMed:15361868, CC ECO:0000269|PubMed:22095711, ECO:0000269|PubMed:23956435}.

Cytoplasm CC {ECO:0000269|PubMed:15361868}. Note=The phosphorylated and active form CC accumulates selectively in the nucleus. CC -!- INDUCTION: Induced by lipopolysaccharide (LPS) (PubMed:27129230). CC Induced by type I interferon (IFN) and viruses (HIV-1 and SeV viruses) CC (PubMed:27129230). {ECO:0000269|PubMed:27129230}. CC -!- PTM: Acetylation inhibits its DNA-binding ability and activity. CC {ECO:0000250}. CC -!- PTM: In response to a viral infection, phosphorylated by TBK1 and CC IKBKE1. Phosphorylation, and subsequent activation is inhibited by CC vaccinia virus protein E3. In TLR7- and TLR9-mediated signaling CC pathway, phosphorylated by IRAK1 (By similarity). {ECO:0000250}. CC -!- PTM: TRAF6-mediated ubiquitination is required for IRF7 activation CC (PubMed:15361868, PubMed:22095711). TRIM35 mediates IRF7 'Lys-48'- CC linked polyubiquitination and subsequent proteasomal degradation (By CC similarity). 'Lys-48'-linked polyubiquitination and subsequent CC proteasomal degradation is NMI-dependent in response to Sendai virus CC infection (PubMed:23956435). Ubiquitinated by UBE3C, leading to its CC degradation (By similarity). {ECO:0000250|UniProtKB:Q92985, CC ECO:0000269|PubMed:15361868, ECO:0000269|PubMed:22095711, CC ECO:0000269|PubMed:23956435}. CC -!- PTM: Sumoylated by TRIM28, which inhibits its transactivation activity. CC {ECO:0000250}. CC -!- PTM: 'Lys-63'-linked ubiquitination by NEURL3 promotes IRF7 activation. CC {ECO:0000250|UniProtKB:Q92985}. CC -!- SIMILARITY: Belongs to the IRF family. {ECO:0000255|PROSITE- CC ProRule:PRU00840}.
