Calpastatin (CAST) is an important gene for meat quality traits in livestock and poultry. The cDNA of caprine CAST gene was amplified for the first time using RACE-PCR. Results showed the full-length cDNA of caprine CAST gene (Accession no. GU944861) was 2435 base pair (bp) and contained a 2187 bp open reading frame encoding a protein with 728 amino acid residues. Bioinformatic analysis indicated that caprine CAST cDNA was 89.8–95.4, 83.5–92.2, 72.8–81.8 and 69.8–73.5% identical to sheep, cattle, pig and human CAST cDNA. It was predicted that caprine CAST contained four conserved domains with 42 serine phosphorylation loci, 18 threonine phosphorylation loci, 1 tyrosine phosphorylation locus and 5 specific PKC phosphorylation loci. This work provided an important experimental basis for further research on the function of CAST in goat.
