Multiple sequence alignment of OASL proteins. Pig OAS1 protein is set as the reference sequence. Fragments containing triple Asp (D) residues are demonstrated. Residues homologues to pig OAS1 D74, D76 and D147 are colored in yellow. a Reptilian OASL. b Avian OASL. c Mammalian OASL1. d Mammalian OASL2
