维甲酸诱导基因-I^[5]（RIG-I，retinoic acid-inducible gene I）是脊椎动物细胞质中的一种模式识别受体（PRR），结构上属于DExD/H-box（英语：DExD/H box proteins）类RNA解旋酶^[6]^[7]^[8]，在人类基因组中由DDX58基因编码^[9]，其N端有两个CARD结构域（英语：CARD domain），C端则可与RNA结合，为先天免疫反应中的重要蛋白^[6]^[7]。

RIG-I平时处于不活化状态，在细胞被西尼罗河病毒、黄热病毒（英语：Flavivirus）、日本脑炎病毒、A型流感病毒、仙台病毒与冠状病毒等RNA病毒感染后^[6]^[10]，RIG-I可与病毒的双股RNA（dsRNA）结合而被活化，接著即可以CARD结构域和粒线体外膜上的线粒体抗病毒信号蛋白（英语：Mitochondrial antiviral-signaling protein）（MAVS）结合^[7]，启动第一型干扰素（英语：Interferon type I）（IFN I）途径的免疫反应^[6]，后者可阻止病毒扩散、造成发炎反应以及协助活化后天免疫^[11]。除识别病毒RNA外，在不同癌细胞中RIG-I还能启动其他反应，包括促进或抑制肿瘤增殖（因肿瘤类型而异）、活化B细胞、影响细胞分化等^[12]。有些无脊椎动物（牡蛎）也具有和RIG-I与MAVS同源的蛋白，且可能也有抗病毒的免疫功能^[13]
