摘  要:
克隆得一株新分离病毒草鱼呼肠孤病毒(GCRV)096的长为1 981 bp的vp4基因,分析该基因的生物信息及其编码蛋白的特性。生物信息学分析表明,同一基因型GCRV分离株vp4基因间的差异不大,但不同基因型GCRV分离株vp4基因间却存在很大的差异。GCRV 096 VP4蛋白含有多个功能位点、2个跨膜结构域及多个潜在的抗原决定簇。构建p EGFP-N3-VP4真核表达质粒,并转染至草鱼肾(Ctenopharyngodon idellus kidney,CIK)细胞中,经荧光显微镜观察和Western blot鉴定,表明GCRV 096 VP4融合蛋白在CIK细胞中得以成功表达。

摘  要:
GCRV 096 is a new grass carp reovirus strain. The vp4 gene 1 981 bp in length in GCRV 096 is cloned, and the characteristics of the vp4 genes and the VP4 proteins in GCRVs are analyzed. Results of bioinformatics analysis show that there is little difference between the vp4 genes in GCRV strains attributed to the same genotype, but the difference between vp4 genes in GCRV strains attributed to different genotypes is much more. The VP4 protein contains multiple functional sites, two transmembrane domain and many potential antigenic eukaryotic determinants. Furthermore, the expression plasmid p EGFP-N3-VP4 of the vp4 gene in GCRV 096 is constructed and transformed into Ctenopharyngodon idellus kidney(CIK) cells. Fluorescence microscope and western blot results indicate that the VP4 fusion protein is successfully expressed in CIK cells.
