Abstract:

The purpose of this study was to clone the full-length cDNA of tree shrew's Tssk6 gene, to elucidate its tissue expression profiles and fundamental bioinformatical characteristics. In the present study, the full-length cDNA of tree shrew's Tssk6 gene was cloned with specific primers on the basis of predicted mRNA sequence of tree shrew's Tssk6 gene in GenBank, the mRNA expression of Tssk6 gene in various tree shrew's tissues was investigated via Real-time PCR. In addition, the bioinformatics on nucleotide sequence of CDS region of Tssk6 cDNA in tree shrew as well as putative protein structure had been analyzed. The results showed that:The CDS region of tree shrew's Tssk6 cDNA contained 822 bp encoding 273 amino acids; Tssk6 gene specifically expressed in tree shrew's testis; Based on the molecular phylogenetic tree constructed with CDS of Tssk6 cDNA among tree shrew and other eight mammalian species, it was inferred that tree shrew was genetically close to primates like human, chimpanzee and rhesus monkey, while it was genetically far to rodents like mouse, rat and golden hamster. This study would lay a foundation for the further study of Tssk6 gene function in tree shrew.
