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.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nRIG-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.\u003cbr\u003e\nPathways\u003cbr\u003e\nRIG-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.\u003cbr\u003e\nRIG-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.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46845089611945,"sku":"ab257916","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab257916","provider":"Iright","version":"1.0","type":"link"}
