Abstract

Sus scrofa is considered an important animal for meat production. During the last decade pork quality is one of the main selection criteria for breeding in the swine industry and thus attracted much more research focus. Jeju Native Pig (JNP) is a typical pig breed in South Korea highly appreciated by Korean consumers; however the slower growth rate and lighter carcass weight than commercial pig breeds led the farmers move away from traditional pig farming to typically intensively muscular traits farming. One recent approach relies to identify the key gene and its SNPs as molecular markers and have been tried for their use in traceability systems in livestock. The present study focused on the association of polymorphisms in the Myosin binding protein H (MyBPH) with skeletal muscle development in the JNP and Berkshire pigs. Validation of expression of genes in the laboratory also supported the idea of differential expression of MyBPH conceived through the in silico analysis. Gene ontology analysis of MyBPH showed significant association with muscle contraction and muscle organ development. The concordant in silico analysis of MyBPH by using the various tools identified potential four nsSNPs (W93T, D218R, D230W and W315V) in JNP. Our nsSNPs analysis retrieved high deleterious effects at second coding region in JNP compared with Berkshire. This study is an in-depth pioneering in silico analysis of polymorphic MyBPH and will be a valuable resource for further targeted molecular diagnosis and population-based studies for improving the growth performance of the JNP.
