Schematic representation of the ANV genome. Open boxes, ORFs. The locations of three ORFs, predicted transmembrane helices (MB), protease (Pro), nuclear localization signal (NLS), ribosomal frameshift structure (RFS), RNA-dependent RNA polymerase (Pol), and stem-loop II-like motif (s2m) are indicated. Numbering is according to the ANV genonic sequence (accession no. AB033998).
