| Abstract_FL | [Objectives]Vanin is a class of pantetheinase and plays an important role in lipid metabolism.The purpose of this study is to amplify the cDNA sequence of goose vanin subgenotype(VNN1)and detect the expression of VNN1 gene in different tissues. [Methods]In this study,the full-length cDNA of goose vanin subgenotype Vanin subgenotype (VNN1) gene was cloned by reverse transcription PCR and rapid amplification cDNA ends(RACE)with the total RNA from liver as template. The bioinformatics analysis and the expression detection of VNN1 mRNA in various tissues by real-time fluorescent quantitative PCR(qPCR)were performed, respectively. [Results]The results showed that the full-length cDNA of goose VNN1 gene(GenBank No.KY399733)was 1 924 bp in length,which contained 1 476 bp open reading frame,35 bp 5′UTR and 417 bp 3′UTR,encoding 491 amino acids. The VNN1 protein was predicted as a kind of unstable protein,which is composed of 7 646 atoms with the relative molecular weight of 54 870.61 and pI of 5.23. The three-dimensional structures of VNN1 protein prediction online between Anser anser and Anas platyrhynchos showed highly similar helix and fold. Sequence analysis showed that the nucleotide and amino acid homologies of VNN1 between Anser anser and Anas platyrhynchos were relatively high. Phylogenetic tree analysis showed the close affinity between Anser anser and Anas platyrhynchos. The qPCR results showed that the expression of goose VNN1 gene in the liver was significantly higher than that in the small intestine,kidney,spleen and lung(P<0.01). [Conclusions]This study has provided the full-length cDNA sequence of goose VNN1 gene,which is highly expressed in the liver. |
