维甲酸诱导基因-I[5]RIG-I,retinoic acid-inducible gene I)是脊椎動物細胞質中的一種模式识别受体(PRR),結構上屬於DExD/H-box英语DExD/H box proteinsRNA解旋酶[6][7][8],在人類基因組中由DDX58基因編碼[9],其N端有兩個CARD結構域英语CARD domainC端則可與RNA結合,為先天免疫反應中的重要蛋白[6][7]

RIG-I平時處於不活化狀態,在細胞被西尼羅河病毒黃熱病毒英语Flavivirus日本腦炎病毒A型流感病毒仙台病毒冠狀病毒RNA病毒感染後[6][10],RIG-I可與病毒的雙股RNA(dsRNA)結合而被活化,接著即可以CARD結構域和粒線體外膜上的线粒体抗病毒信号蛋白英语Mitochondrial antiviral-signaling protein(MAVS)結合[7],啟動第一型干擾素英语Interferon type I(IFN I)途徑的免疫反應[6],後者可阻止病毒擴散、造成發炎反應以及協助活化後天免疫[11]。除識別病毒RNA外,在不同癌細胞中RIG-I還能啟動其他反應,包括促進或抑制腫瘤增殖(因腫瘤類型而異)、活化B細胞、影響細胞分化[12]。有些無脊椎動物牡蠣)也具有和RIG-I與MAVS同源的蛋白,且可能也有抗病毒的免疫功能[13]
