(a) (b) Figure S1. Amino acid sequence alignment of human and pig FSD2. The amino acid sequence of porcine FSD2 (determined in this study), is aligned to that from (a) pig (Sus scrofa, Genbank accession no.XP_005666169.1) and (b) human (Homo sapiens, Genbank accession no.NP_001007123.1). Identical amino acids are presented with a gray background. The red box indicates the additional amino acids in porcine FSD2.

Putative transcription factor binding sites in the 1,000-bp region upstream of porcine FSD2 related to tissue-specific expression. Green and red boxes indicate transcription factor binding sites identified using ALGGEN-PROMO and TRANSFAC, respectively.
Arg333 Gly333 FN3 FN3 FN3 FN3 Figure S3. The predicted protein structure of porcine FSD2 derived from amino acid residues 296 to 561. The substitution of Arg (a) in haplotype 1 to Gly (b) in haplotype 2 at position 333 is located near SNP10 (marked in purple). The porcine FSD2 structure of helix and fibronectin type III (FN3) domains are represented in red and sky-blue, respectively.
