A full-length NS3 (NS3F) and a truncated protein (NS3H) with an RNA helicase domain possess activity. Using in vitro system monocistronic reporter or DNA, containing the CSFV 5′-UTR, we observed that both NS3F NS3H enhanced internal ribosome entry site (IRES)-mediated cellular translation dose-dependent manner, but protease (NS3P) lacks did not. was stronger than promoting translations. These results showed viral could promote translation, higher activity might be more efficient. The NS5B...
