Supplementary information

RIG-I also known as DDX58 is an important protein with mass of approximately 102 kDa. This protein acts as a cytosolic sensor for viral double-stranded RNA playing an essential role in the detection of viral infections. It is expressed in many cell types including immune and epithelial cells. RIG-I consists of two N-terminal caspase activation and recruitment domains (CARDs) a DExD/H box helicase domain and a C-terminal regulatory domain. These domains enable RIG-I to recognize and bind viral RNA initiating downstream signaling for immune responses.

Biological function summary

RIG-I contributes significantly to the innate immune response. It acts to sense viral RNA and triggers the production of type I interferons and other pro-inflammatory cytokines. This protein functions as part of a complex that includes MAVS (mitochondrial antiviral signaling protein) and other signaling adapters. Upon activation RIG-I undergoes a conformational change leading to the exposure of its CARDs which interact with CARDs of MAVS facilitating downstream signaling to induce an antiviral state in host cells.

Pathways

RIG-I plays a central role in the RNA sensing pathway critical for antiviral immunity. This pathway involves several steps beginning with the recognition of viral RNA leading to the activation of interferon regulatory factors like IRF3 and IRF7 as well as nuclear factor kappa B (NF-κB). These factors then promote the expression of interferon-stimulated genes (ISGs). RIG-I also relates closely to the Jak-STAT signaling pathway which is activated by interferons and enhances the transcription of ISGs further amplifying the antiviral response.

RIG-I is often associated with viral infections such as hepatitis C and influenza. By detecting viral RNA RIG-I activates immune responses that help to control these infections. However dysfunction or aberrations in RIG-I signaling can lead to autoimmune disorders such as Aicardi-Goutières syndrome where there is an inappropriate response to self nucleic acids. In these disease contexts RIG-I interacts with MAVS and indirectly with proteins involved in regulating immune responses such as STING which plays a role in the innate immune response against DNA viruses.

Target data

Innate immune receptor that senses cytoplasmic viral nucleic acids and activates a downstream signaling cascade leading to the production of type I interferons and pro-inflammatory cytokines. Forms a ribonucleoprotein complex with viral RNAs on which it homooligomerizes to form filaments. The homooligomerization allows the recruitment of RNF135 an E3 ubiquitin-protein ligase that activates and amplifies the RIG-I-mediated antiviral signaling in an RNA length-dependent manner through ubiquitination-dependent and -independent mechanisms. Upon activation, associates with mitochondria antiviral signaling protein (MAVS/IPS1) that activates the IKK-related kinases TBK1 and IKBKE which in turn phosphorylate the interferon regulatory factors IRF3 and IRF7, activating transcription of antiviral immunological genes including the IFN-alpha and IFN-beta interferons. Ligands include : 5'-triphosphorylated ssRNA and dsRNA and short dsRNA (<1 kb in length). In addition to the 5'-triphosphate moiety, blunt-end base pairing at the 5'-end of the RNA is very essential. Overhangs at the non-triphosphorylated end of the dsRNA RNA have no major impact on its activity. A 3'overhang at the 5'triphosphate end decreases and any 5'overhang at the 5' triphosphate end abolishes its activity. Detects both positive and negative strand RNA viruses including members of the families Paramyxoviridae : Sendai virus (SeV), Rhabdoviridae and Flaviviridae. It also detects rotavirus and orthoreovirus. Also involved in antiviral signaling in response to viruses containing a dsDNA genome. Detects dsRNA produced from non-self dsDNA by RNA polymerase III. May play important roles in granulocyte production and differentiation, bacterial phagocytosis and in the regulation of cell migration.
