Multiple sequence alignment of the NS1-2 protein representative of different norovirus genogroups.

<p>GI.1 (Norwalk), GI.2 (Southampton), GII.1 (Hawaii), GII.4 (Lordsdale), GIII (Jena) and GV (MNV-1). Completely conserved residues are shown in white on a red background. Identical residues with >50% conservation are shaded in yellow. Similar residues with >50% conservation are shaded in grey. Residue numbers correspond to the MNV-1 NS1-2 sequence.
