Similarity of ORF sequences between reported functional IFN-λ subtypes.

hIFN: human IFN; mIFN: mouse IFN; pIFN: pig IFN; bIFN: bat IFN; cIFN: chicken; fIFN: frog IFN. Values are given as percentages and calculated from the multiple alignment of ORF sequences. Level of similarity was calculated for each pair of aligned sequences as the number of identical resudues divided by the number of aligned residues, excluding positions with gaps and flanking unaligned posittions in both sequences. The bold numbers indicates intraspeices similarities.
