A novel polymorphism of the MYPN gene and its association with meat quality traits in Bos taurus
Myopalladin (MYPN) is a multifunctional protein that maintains sarcomeric integrity and regulates Z-line structure. It is an important candidate gene for meat quality selection through marker-assisted selection. Using PCR-RFLP technology, we discovered a single-nucleotide polymorphism (SNP) (A1795G in exon 9) of the MYPN gene. Allele frequencies of this SNP were investigated and evaluated by the χ2 test in 660 cattle populations in China; only the Nanyang population was not in Hardy-Weinberg equilibrium.
