Sequence alignment of OAS2 and OAS3 proteins. Pig OAS1 is set as the reference sequence. Fragments containing triple D residues are demonstrated. Residues homologous to pig OAS1 D74, D76 and D147 are colored in yellow. a Sequence alignment of OAS2 N terminus and C terminus. b Sequence alignment of OAS3 N terminus, middle domain and C terminus
