A novel pig gene, CPNE1, differentially expressed in the muscle tissues from Wujin pigs and Large White pigs
Journal Title: Animal Science Papers and Reports - Year 2012, Vol 30, Issue 2
Abstract
The mRNA differential display technique was performed to investigate gene expression differences in the longissimus dorsi muscle from Wujin and Large White pigs. A fragment of one differentially expressed gene was isolated and sequenced. A complete cDNA sequence of the gene was obtained using the rapid amplification of cDNA ends (RACE) method. The open reading frame of this gene encodes a protein of 537 amino acids, which is homologous with the Copine I (CPNE1) of eight species: greater horseshoe bat (95%), mouse (92% ), rat (93%), cattle (95%), sheep (95%), rabbit (94%), human (95%) and dog (94%). This newly identified gene was respectively defined as the swine CPNE1 gene and had been assigned GeneID: 100233174. The phylogenetic analysis revealed that the swine CPNE1 gene has a closer genetic relationship with the CPNE1 gene of a dog. The tissue expression analysis indicated that the swine CPNE1 gene has a broad tissue distribution. The experiment described is the first to establish the primary foundation for further research on the swine CPNE1 gene.
