However, although these four proteins are known to be important in the antiviral response, they do not represent the complete repertoire of antiviral effectors. Immunoregulatory mechanisms of interferon view all 30 articles. Many of these substrates are important in the ifn response, including the signalling components jak1 and stat1, prrs such as rigi retinoicacidinducible gene i, and the antiviral effector proteins mxa, pkr and rnasel 24. The interferoninducible protein viperin inhibits influenza virus.
Type i interferons ifns provide the first line of defence against viral infection. Ifninducible transmembrane ifitm proteins have been identified as intrinsic antiviral effectors, which block the entry of a broad spectrum of enveloped rna viruses by interrupting virusendosomal fusion.
