Abstract: This study uses bioinformatics method to analyze the function and property of H-FABP gene encoding protein of Gansu black pig. DNA pooling and direct sequencing techniques were used for SNPs rapid screening and the function prediction of H-FABP protein of Gansu black pig. The results showed that the CDS region of H-FABP gene in Gansu black pig was 402 bp, encoding 133 amino residues, 4 SNPs in CDS region including C734T-Intron1, T152C-Exon2,G30A-Intron2 and T121G-Intron2. Among them, T152C-Exon2 was a missense mutation, and the amino acids were converted from threonine (Ile) to threonine (Thr). The bioinformatics prediction showed that H-FABP protein of Gansu black pig was a stable hydrophilic protein, and the secondary structure and tertiary structure were mixed protein mainly with β-fold.
