| Abstract: | Objective] To study the role of ubiquitin-conjugating enzyme cgsUBE2L3 gene during the immune response in Chinese giant salamander (Andrias davidianus).Method] To clone ubiquitin-conjugating enzyme gene from Chinese giant salamander (cgsUBE2L3) and analyzed its amino acids by bioinformatics software,the tissue distribution and expression profile with the stimulation of lipopolysaccharide (LPS) were detected by qRT-PCR.Result] Successfully,we cloned cgsUBE2L3 gene.The full-length cDNA of cgsUBE2L3 contained an open reading frame of 462 bp,encoding a protein of 154 amino acids with a putative weight of 21.2 ku.The cgsUBE2L3 had a highly conserved amino acid sequence and shared the highest identity of 97.4% with African clawed frog.Quantitative real time PCR results showed that the cgsUBE2L3 gene was widely distributed in the Chinese giant salamander tissues and the mRNA levels of cgsUBE2L3 were significantly changed in the immu-ne-associated tissues of LPS-infected Chinese giant salamander.Conclusion] The cgsUBE2L3 gene has highly conserved structural feature and tissue-specific of mRNA expression.Moreover,it participates in the immune response of Chinese giant salamander to resist LPS stimulation. |
