CC   -!- FUNCTION: Key transcriptional regulator of type I interferon (IFN)-
CC       dependent immune responses which plays a critical role in the innate
CC       immune response against DNA and RNA viruses (PubMed:22394562,
CC       PubMed:25636800, PubMed:27302953). Regulates the transcription of type
CC       I IFN genes (IFN-alpha and IFN-beta) and IFN-stimulated genes (ISG) by
CC       binding to an interferon-stimulated response element (ISRE) in their
CC       promoters (PubMed:11846977, PubMed:16846591, PubMed:16979567,
CC       PubMed:20049431, PubMed:32972995). Acts as a more potent activator of
CC       the IFN-beta (IFNB) gene than the IFN-alpha (IFNA) gene and plays a
CC       critical role in both the early and late phases of the IFNA/B gene
CC       induction (PubMed:16846591, PubMed:16979567, PubMed:20049431). Found in
CC       an inactive form in the cytoplasm of uninfected cells and following
CC       viral infection, double-stranded RNA (dsRNA), or toll-like receptor
CC       (TLR) signaling, is phosphorylated by IKBKE and TBK1 kinases
CC       (PubMed:22394562, PubMed:25636800, PubMed:27302953). This induces a
CC       conformational change, leading to its dimerization and nuclear
CC       localization and association with CREB binding protein (CREBBP) to form
CC       dsRNA-activated factor 1 (DRAF1), a complex which activates the
CC       transcription of the type I IFN and ISG genes (PubMed:16154084,
CC       PubMed:27302953, PubMed:33440148). Can activate distinct gene
CC       expression programs in macrophages and can induce significant apoptosis
CC       in primary macrophages (PubMed:16846591). In response to Sendai virus
CC       infection, is recruited by TOMM70:HSP90AA1 to mitochondrion and forms
CC       an apoptosis complex TOMM70:HSP90AA1:IRF3:BAX inducing apoptosis
CC       (PubMed:25609812). Key transcription factor regulating the IFN response
CC       during SARS-CoV-2 infection (PubMed:33440148).

CC   -!- ACTIVITY REGULATION: In the absence of viral infection, maintained as a
CC       monomer in an autoinhibited state (PubMed:16846591, PubMed:16979567,
CC       PubMed:20049431). Phosphorylation by TBK1 and IKBKE 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 (PubMed:25636800). Phosphorylation
CC       and activation follow the following steps: innate adapter protein MAVS,
CC       STING1 or TICAM1 are first activated by viral RNA, cytosolic DNA and
CC       bacterial lipopolysaccharide (LPS), respectively, leading to activation
CC       of the kinases TBK1 and IKBKE (PubMed:25636800). These kinases then
CC       phosphorylate the adapter proteins on their pLxIS motif, leading to
CC       recruitment of IRF3, thereby licensing IRF3 for phosphorylation by TBK1
CC       (PubMed:25636800). Phosphorylated IRF3 dissociates from the adapter
CC       proteins, dimerizes, and then enters the nucleus to induce IFNs
CC       (PubMed:25636800, PubMed:27302953). {ECO:0000269|PubMed:25636800,

CC   -!- TISSUE SPECIFICITY: Expressed constitutively in a variety of tissues.
CC   -!- PTM: Constitutively phosphorylated on many Ser/Thr residues
CC       (PubMed:22394562, PubMed:23478265, PubMed:23746807). Activated
CC       following phosphorylation by TBK1 and IKBKE (PubMed:23478265,
CC       PubMed:23746807, PubMed:25636800). Innate adapter protein MAVS, STING1
CC       or TICAM1 are first activated by viral RNA, cytosolic DNA, and
CC       bacterial lipopolysaccharide (LPS), respectively, leading to activation
CC       of the kinases TBK1 and IKBKE (PubMed:25636800). These kinases then
CC       phosphorylate the adapter proteins on the pLxIS motif, leading to
CC       recruitment of IRF3, thereby licensing IRF3 for phosphorylation by TBK1
CC       (PubMed:25636800). Phosphorylated IRF3 dissociates from the adapter
CC       proteins, dimerizes, and then enters the nucleus to induce IFNs
CC       (PubMed:25636800). {ECO:0000269|PubMed:22394562,

CC       ubiquitination involves TRIM21 leading to proteasomal degradation

CC   -!- PTM: ISGylated by HERC5 resulting in sustained IRF3 activation and in
CC       the inhibition of IRF3 ubiquitination by disrupting PIN1 binding. The
CC       phosphorylation state of IRF3 does not alter ISGylation.

CC   -!- PTM: Proteolytically cleaved by apoptotic caspases during apoptosis,
CC       leading to its inactivation (PubMed:30878284). Cleavage by CASP3 during
CC       virus-induced apoptosis inactivates it, preventing cytokine
CC       overproduction (PubMed:30878284). {ECO:0000269|PubMed:30878284}.
CC   -!- PTM: (Microbial infection) ISGylated. ISGylation is cleaved and removed
CC       by SARS-COV-2 nsp3 which attenuates type I interferon responses.

CC   -!- DISEASE: Encephalopathy, acute, infection-induced, 7, herpes-specific
CC       (IIAE7) [MIM:616532]: A rare complication of human herpesvirus 1 (HHV-
CC       1) infection, occurring in only a small minority of HHV-1 infected
CC       individuals. It is characterized by hemorrhagic necrosis of parts of
CC       the temporal and frontal lobes. Onset is over several days and involves
CC       fever, headache, seizures, stupor, and often coma, frequently with a
CC       fatal outcome. {ECO:0000269|PubMed:26216125}. Note=Disease
CC       susceptibility is associated with variants affecting the gene
CC       represented in this entry.
