dc.description.abstractRIG-I and mda-5 are activated by viral RNA and stimulate type I interferon production. Laboratory of genetics and physiology 2 (LGP2) shares homology with RIG-I and mda-5 but lacks the CARD domains required for signaling. The V proteins of paramyxoviruses limit interferon induction by binding mda-5 and preventing its activation; however, they do not bind RIG-I and have not been considered inhibitors of RIG-I signaling. Here we uncover a novel mechanism of RIG-I inhibition in which the V protein of parainfluenzavirus type 5 (PIV5; formerly known as simian virus type 5 [SV5]) interacts with LGP2 and cooperatively inhibits induction by RIG-I ligands. A complex between RIG-I and LGP2 is observed in the presence of PIV5-V, and we propose that this complex is refractory to activation by RIG-I ligands. The V proteins from other paramyxoviruses also bind LGP2 and demonstrate LGP2-dependent inhibition of RIG-I signaling. This is significant, because it demonstrates a general mechanism for the targeting of the RIG-I pathway by paramyxoviruses.en
