Zika virus dumbbell-1 structure is critical for sfRNA presence and cytopathic effect during infection

Abstract excerpt

ABSTRACT All flaviviruses contain conserved RNA structures in the 3′ untranslated region (3′ UTR) that are important for flavivirus RNA replication, translation, and pathogenesis. Flaviviruses like Zika virus (ZIKV) contain multiple conserved RNA structures in the viral 3′ UTR, including the structure known as dumbbell-1 (DB-1). Previous research has shown that the DB-1 structure is important for flavivirus...
