Viperin Targets nsp8 to Block Coronavirus Replication
2026-09-07
The 2026 reference study identifies a non-catalytic antiviral function of viperin: direct binding to coronavirus nsp8 disrupts replication-transcription complex assembly and reduces RNA-dependent RNA polymerase activity. Using porcine deltacoronavirus as a model, the work separates this mechanism from ddhCTP-mediated chain termination and suggests that the conserved viperin–nsp8 interface could inform broad-spectrum antiviral drug development.
