A recent study has revealed that PP1alpha and PP1gamma phosphatases are responsible for dephosphorylating MDA5 and are essential for its activation. |PP1gamma mediates dephosphorylation of MDA5 not only at Ser-88 but also at other Ser/Thr residues. |

Initially, RIG-I and MDA5 sense dsRNA in the cytoplasm, produced as a by-product of RNA virus replication.Once one or both of these sensors are activated, they interact with a mitochondrial membrane protein called MAVS (mitochondrial antiviral) (also called IPS1, Cardif, and VISA). They signal to the mitochondrial membrane protein MAVS, which in turn activates the kinases TBK1 and IKKɛ. |

Here we show that the coronavirus endonuclease (EndoU) activity is key to prevent early induction of double-stranded RNA (dsRNA) host cell responses. Replication of EndoU-deficient coronaviruses is greatly attenuated in vivo and severely restricted in primary cells even during the early phase of the infection. Collectively our results demonstrate that the coronavirus EndoU efficiently prevents simultaneous activation of host cell dsRNA sensors, such as Mda5, OAS and PKR. It is thus tempting to propose that viral dsRNA represents the natural substrate of the coronavirus EndoU. However, it remains to be determined which kind of viral dsRNA is cleaved by the EndoU or triggers Mda5, OAS, and PKR activation. |

Here, we found that RIG-I undergoes proteasomal degradation after conjugation to ubiquitin by RNF125. Further, RNF125 conjugates ubiquitin to MDA5, a family protein of RIG-I as well as IPS-1, which is also a downstream protein of RIG-I signaling that results in suppressing the functions of these proteins. Because RNF125 is enhanced by IFN, these functions constitute a negative regulatory loop circuit for IFN production. |
