Figure 1From: PB1-F2 Finder: scanning influenza sequences for PB1-F2 encoding RNA segmentsSummary of PB1-F2 sequences classified by their lengths. Upper: candidate PB1-F2 peptides show up to 35% sequence dissimilarity compared to a panel of reference sequences from Swiss-Prot. The population with distances above 86% represents non-PB1-F2 ORF translations. Lower: number of PB1-F2 sequences in each group length.Back to article page
