Identification of Type II Interferon Receptors in Geese: Gene Structure, Phylogenetic Analysis, and Expression Patterns

Figure 1

Nucleotide sequences of goose IFNGRs and deduced amino acid sequence structure. (a) Nucleotide sequence of goose IFNGR1 and the deduced amino acid sequence. The 5′-UTR and 3′-UTR sequences are shown in lowercase letters, while the ORF is presented in uppercase letters. The putative amino acid sequence is highlighted in blue and presented below the capital letters. Potential N-glycosylation sites are boxed. (b) Nucleotide sequence of goose IFNGR2 and deduced amino acid sequence. (c) Predicted protein domains characteristic of IFNGR1 and their alignment with counterparts from other birds and mammals. Conserved sequences are represented by the graph under the alignment. TM domains are marked in light yellow. (d) Predicted protein domains characteristic of IFNGR2. TM domains are marked in light yellow, while the fibronectin type III domain (FN3) is marked in light red.
