The Analysis of the MspI Polymorphism within Exon 3 of the Calpastatin Gene in Slovak Simmental Cattle

Michal Gábor, Anna Trakovická, Martina Miluchová

Abstract


Calpastatin has important function in the tenderization process. The SNP polymorphisms in the calpastatin gene suchas UoG-CAST (intron 5) and CAST-T1 (3´UTR region) are used as markers in commercial test for prediction ofanimals with tenderness meat. The others research of the calpastatine gene confirmed the impact of a SNPpolymorphism in exon 3 on fertility and longevity in dairy cattle, too. The aim of this study was to analyse thepopulation of 113 animals of Slovak Simmental (42 bulls and 71 cows) for the missense SNP polymorphism in exon3. Bovine genomic DNA was isolated from sperm and blood by commercial kit. The SNP CAST c.283 C>T wasdetected by PCR-RFLP method with restriction endonuclease MspI. The favourable allele C was detected by tworestriction fragments 135 bp and 173 bp and the allele T with the one 308 bp fragment. In the analyzed population ofSlovak Simmental cattle were detected the following frequency of alleles and genotypes for the SNP c.283 C>T ofthe CAST gene. Frequencies of allele C and allele T were 0.6460 and 0.3540 and frequencies of genotypes were0.4336 (genotype CC), 0.4248 (genotype CT) and 0.1416 (genotype TT).
