Key result
Exchange of domain II in chimeric HCV/CSFV 5'NTRs abolished replication with minor effects on translation, whereas exchange of domain III subdomains severely decreased translation but maintained replication.

Highlights separable HCV 5'NTR domain functions in replication versus translation; leaves open targeted antiviral strategies pending further validation.
HCV RNA elements involved in translation and replication overlap, with domain II being essential for replication and domain III subdomains being critical for translation.
Reusken et al. (2003) studied Hepatitis C virus (HCV). Chimeric HCV/CSFV 5'NTRs was evaluated on Translation efficiency and viral RNA replication. Exchange of domain II in chimeric HCV/CSFV 5'NTRs abolished replication with minor effects on translation, whereas exchange of domain III subdomains severely decreased translation but maintained replication.
