CC   -!- FUNCTION: Innate immune receptor which acts as a cytoplasmic sensor of
CC       viral nucleic acids and plays a major role in sensing viral infection
CC       and in the activation of a cascade of antiviral responses including the
CC       induction of type I interferons and pro-inflammatory cytokines
CC       (PubMed:32169843, PubMed:33727702). Its ligands include mRNA lacking
CC       2'-O-methylation at their 5' cap and long-dsRNA (>1 kb in length)
CC       (PubMed:22160685). Upon ligand binding it associates with mitochondria
CC       antiviral signaling protein (MAVS/IPS1) which activates the IKK-related
CC       kinases: TBK1 and IKBKE which phosphorylate interferon regulatory
CC       factors: IRF3 and IRF7 which in turn activate transcription of
CC       antiviral immunological genes, including interferons (IFNs); IFN-alpha
CC       and IFN-beta. Responsible for detecting the Picornaviridae family
CC       members such as encephalomyocarditis virus (EMCV) and mengo
CC       encephalomyocarditis virus (ENMG). Detects coronavirus SARS-CoV-2
CC       (PubMed:33440148, PubMed:33514628). Can also detect other viruses such
CC       as dengue virus (DENV), west Nile virus (WNV), and reovirus. Also
CC       involved in antiviral signaling in response to viruses containing a
CC       dsDNA genome, such as vaccinia virus. Plays an important role in
CC       amplifying innate immune signaling through recognition of RNA
CC       metabolites that are produced during virus infection by ribonuclease L
CC       (RNase L). May play an important role in enhancing natural killer cell
CC       function and may be involved in growth inhibition and apoptosis in
CC       several tumor cell lines. {ECO:0000269|PubMed:14645903,

CC       Aicardi-Goutieres syndrome, a genetically heterogeneous disease
CC       characterized by cerebral atrophy, leukoencephalopathy, intracranial
CC       calcifications, chronic cerebrospinal fluid (CSF) lymphocytosis,
CC       increased CSF alpha-interferon, and negative serologic investigations
CC       for common prenatal infection. Clinical features as thrombocytopenia,
CC       hepatosplenomegaly and elevated hepatic transaminases along with
CC       intermittent fever may erroneously suggest an infective process. Severe
CC       neurological dysfunctions manifest in infancy as progressive
CC       microcephaly, spasticity, dystonic posturing and profound psychomotor
CC       retardation. Death often occurs in early childhood.
CC       {ECO:0000269|PubMed:24686847, ECO:0000269|PubMed:24995871}. Note=The
CC       disease is caused by variants affecting the gene represented in this
CC       entry.
CC   -!- DISEASE: Singleton-Merten syndrome 1 (SGMRT1) [MIM:182250]: An
CC       autosomal dominant disorder with variable expression. Core features are
CC       marked aortic calcification, dental anomalies, osteopenia, acro-
CC       osteolysis, and to a lesser extent glaucoma, psoriasis, muscle
CC       weakness, and joint laxity. Dental anomalies include delayed eruption
CC       and immature root formation of anterior permanent teeth, early loss of
CC       permanent teeth due to short roots, acute root resorption, high caries,
CC       and aggressive alveolar bone loss. Additional clinical manifestations
CC       include particular facial characteristics and abnormal joint and muscle
CC       ligaments. {ECO:0000269|PubMed:25620204}. Note=The disease is caused by
CC       variants affecting the gene represented in this entry.
CC   -!- MISCELLANEOUS: In HIV-1 infected HeLa-CD4 cells, overexpression of
CC       IFIH1 results in a great increase in the level of secreted viral p24
CC       protein.
CC   -!- SIMILARITY: Belongs to the helicase family. RLR subfamily.
CC       {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAH78180.1; Type=Miscellaneous discrepancy; Note=Contaminating sequence. Potential poly-A sequence.; Evidence={ECO:0000305};
CC       Sequence=BAB71141.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
