Journal Article
Mohd Jaafar, F., Belhouchet, M., Monsion, B., Bell-Sakyi, L., Mertens, P. P. C., & Attoui, H. (2023). Orbivirus NS4 Proteins Play Multiple Roles to Dampen Cellular Responses. Viruses, 15(9), Article 1908. https://doi.org/10.3390/v15091908

Non-structural protein 4 (NS4) of insect-borne and tick-borne orbiviruses is encoded by genome segment 9, from a secondary open reading frame. Though a protein dispensable for bluetongue virus (BTV) replication, it has been shown to counter the inter...
