Mammalian retinoic acid-inducible gene I (RIG-I) is a chief antiviral gene sensing viral RNA molecules including Newcastle disease virus (NDV). In this study, goose RIG-I gene (gRIG-I) was identified. The 2805 bp-long gene encodes a gRIG-I protein that exhibits 93.8% amino acid identity to duck RIG-I. DF-1 chicken fibroblast cells transfected with full-length of gRIG-I or CARD domain of gRIG-I plasmids respond significantly to the agonist of 21-mer 5'ppp RNA, evident through enhancement of IF...Expand abstract
