摘要
Mx蛋白属于大GTP酶的动态蛋白(dynamin)超家族,在体内由I型IFN诱导。大多数的脊椎动物有1—3个不同细胞内定位的Mx蛋白异构体,一般定位于核内或胞质中。Mx蛋白具有广谱的抗病毒能力,对RNA病毒,如流感病毒、水泡性口炎病毒、托高土病毒、汉坦病毒和狂犬病毒等有作用,甚至对DNA病毒(如乙型肝炎病毒)也有一定的作用。本文论述了Mx蛋白的结构,并探讨了各个种属来源的Mx蛋白抑制不同病毒的作用及机制。
Mx proteins belong to the dynamin superfamily of large GTPase, and are induced by type I interferon in vivo. Most vertebrates possess one to three Mx isomers which locate in either nucleus or cytoplasm. Mx protein can resist a variety of viruses including both RNA and DNA virus, such as influenza virus VSV, Thogoto virus, hantaviruses, rabies virus, HBV. This article reviews the structure and antiviral functions of Mx proteins.
