中文摘要:应用RACE PCR克隆了草鱼NCCRP-1基因。结果表明,NCCRP-1cDNA全长900 bp,开放阅读框为714 bp,编码237个氨基酸残基,预测分子量为27.3 kD,理论等电点为5.63。草鱼NCCRP-1具有NCCRP-1蛋白家族保守的功能区域,与鲤鱼该基因(Cyprinus carpioL.)的相似性为88%。将此基因定向插入原核表达载体pET-32a,构建重组质粒pET-NCCRP后转化BL2(1DE3)进行诱导表达。SDS-PAGE分析显示在47.8 kD处出现特异性蛋白条带,Western blot检测表明草鱼NCCRP-1融合蛋白成功表达。
外文摘要:In the present study, grass carp ( Ctenopharyngodon idellus ) NCCRP-1 gene was cloned using RACE method. The full length cDNA of NCCRP-1 was 900 bp containing a 714 bp open reading frame ( ORF ), which encoded 237 amino acids with predicted molecular mass of 27.3 kD and a theoretical pI of 5.63. Amino acid alignment indicated that grass carp NCCRP-1 possessed consensus functional domians of NCCRP-1 family and shared 88% similarity with common carp NCCRP-1, The prokaryotic expression vector pET-NCCRP was constructed and then transformed into BL21 ( DE3 ) . SDS-PAGE and Western blotting analysis indicated that the recombinant protein of grass carp NCCRP-1 was successfully expressed and molecular weight of expressed fusion protein was 47.8 kD.
