  1. 3 amino acids of the NS1 protein (34, 97 and 101) within the ISG15 binding site display variability. I: Specimens clustering in cluster I of the NS phylogenetic tree. II: Specimens clustering in cluster II of the NS phylogenetic tree. III: Specimens clustering in cluster III of the NS phylogenetic tree. Rest of DSO Specimens: rest of specimens sequenced in this study not individually listed in this table. Identical amino acids are marked by a dot (.).
