Fig 1. Schematic representation of the NSP3 cytoplasmic-expression vector (A), reporter mRNA (B) and standard mRNA (C) used.

The NSP3 expression vector was transfected as DNA in BSRT7 cells. The capped reporter mRNA ending with the canonical GACC (R-RNA) or non-canonical (Nc-RNA) terminal sequence was electroporated with the standard RNA (S-RNA).
