研究背景
Innate immune receptor which acts as a cytoplasmic sensor of viral nucleic acids and plays a major role in sensing viral infection and in the activation of a cascade of antiviral responses including the induction of type I interferons and proinflammatory cytokines. Its ligands include mRNA lacking 2'-O-methylation at their 5' cap and long-dsRNA (>1 kb in length). Upon ligand binding it associates with mitochondria antiviral signaling protein (MAVS/IPS1) which activates the IKK-related kinases: TBK1 and IKBKE which phosphorylate interferon regulatory factors: IRF3 and IRF7 which in turn activate transcription of antiviral immunological genes, including interferons (IFNs); IFN-alpha and IFN-beta. Responsible for detecting the Picornaviridae family members such as encephalomyocarditis virus (EMCV) and mengo encephalomyocarditis virus (ENMG). Can also detect other viruses such as dengue virus (DENV), west Nile virus (WNV), and reovirus. Also involved in antiviral signaling in response to viruses containing a dsDNA genome, such as vaccinia virus. Plays an important role in amplifying innate immune signaling through recognition of RNA metabolites that are produced during virus infection by ribonuclease L (RNase L). May play an important role in enhancing natural killer cell function and may be involved in growth inhibition and apoptosis in several tumor cell lines.
Sumoylated. Sumoylation positively regulates its role in type I interferon induction and is enhanced by PIAS2-beta.
Ubiquitinated by RNF125, leading to its degradation by the proteasome. USP17/UPS17L2-dependent deubiquitination positively regulates the receptor. Ubiquitinated by TRIM25 via 'Lys-63'-linked ubiquitination, promoting activation of IFIH1/MDA5.
During apoptosis, processed into 3 cleavage products. The helicase-containing fragment, once liberated from the CARD domains, translocate from the cytoplasm to the nucleus. The processed protein significantly sensitizes cells to DNA degradation.
(Microbial infection) Cleaved and inactivated by the protease 2A of coxsackievirus B3, poliovirus and enterovirus 71 allowing the virus to disrupt the host type I interferon production.
Cytoplasm. Nucleus.
Note: May be found in the nucleus, during apoptosis.
Widely expressed, at a low level. Expression is detected at slightly highest levels in placenta, pancreas and spleen and at barely levels in detectable brain, testis and lung.
Belongs to the helicase family. RLR subfamily.
