Sequence analysis of Sus scrofa SLC35D3. a Predicted secondary structure of the porcine SLC35D3 amino acid sequence. The blue lines represent α-helixes, red lines represent extended strands, and purple lines represent random coils. b Hydrophobicity profile of Sus scrofa SLC35D3 protein. The y-axis displays hydrophilic index; the x-axis displays the amino acid position. c Predicted tertiary structure of SLC35D3. d Multiple sequence alignment of the deduced amino acid of SLC35D3. e Predicted transmembrane domains of SLC35D3. f Phylogenetic tree of SLC35D3 amino acid sequences from 11 organisms, constructed using the neighbor-joining method
