Cis-acting elements that regulate translation have been identified in the 3' noncoding regions (NCRs) of cellular and viral mRNAs. As one means of analyzing the effect on translation of the conserved 3' terminal RNA structure of the West Nile virus (WNV) genome, the translation efficiencies of chimeric mRNAs composed of a CAT reporter gene flanked by viral or nonviral 5' and 3' terminal sequences were compared. In vitro, the WNV 3'(+) stem loop (SL) RNA reduced the translation efficiencies of chimeric mRNAs with either viral or nonviral 5' NCRs, suggesting that a specific 3'-5' RNA-RNA interaction was not involved. In contrast, the 3' terminal sequence of a togavirus, rubella virus, enhanced translation efficiency. The WNV 3'(+)SL reduced translation efficiency both in cis and in trans and of both capped and uncapped chimeric mRNAs. We have previously reported that three cellular proteins bind specifically to the WNV 3'(+)SL RNA. Competition between the WNV 3'(+)SL and the 5' terminus of the chimeric mRNAs for proteins involved in translation initiation could explain the translation inhibition observed.
