3' cis-acting elements that contribute to the competence and efficiency of Japanese encephalitis virus genome replication: functional importance of sequence duplications, deletions, and substitutions.

Abstract excerpt

The positive-strand RNA genome of Japanese encephalitis virus (JEV) terminates in a highly conserved 3'-noncoding region (3'NCR) of six domains (V, X, I, II-1, II-2, and III in the 5'-to-3' direction). By manipulating the JEV genomic RNA, we have identified important roles for RNA elements present within the 574-nucleotide 3'NCR in viral replication. The two 3'-proximal domains (II-2 and III) were sufficient for...
