摘要:

目的:构建和鉴定带3×Flag标签的人线粒体转录终止因子3基因(hMTERF3)真核表达载体。方法:根据NCBI数据库
中hMTERF3 基因序列设计引物,采用聚合酶链式反应从pGEM-hMTERF3重组克隆载体中扩增出hMTERF3 基因开放阅读框
序列,经Hind Ⅲ和BamHⅠ双酶切后,连接入真核表达载体p3×FLAG-CMV-14的多克隆位点中,构建重组质粒p3×FLAGCMV-
hMTERF3,分别用菌落PCR、限制性核酸内切酶分析和DNA序列分析3种方法鉴定重组子。结果:重组质粒p3×FLAGCMV-
hMTERF3经双酶切鉴定和菌落PCR鉴定均获得大小为1 254 bp的目的条带,DNA序列分析和Blast序列比对结果表明
该序列与GenBank中hMTERF3 基因序列的同源性达到100%,插入基因的大小和方向均正确。结论:成功构建了hMTERF3 基
因的真核表达载体,为进一步研究hMTERF3基因在恶性肿瘤发生发展中的作用奠定了基础。

Abstract:

Objective:To construct and identify the eukaryotic expression vector of FLAG-tagged human MTERF3 gene. Methods:
The human MTERF3 gene was amplified by Polymerase Chain Reaction(PCR). The recombinant products of the p3×FLAG-CMVhMTERF3
were gained by T4 DNA ligase connecting MTERF3 gene fragment and eukaryotic expression vector p3×FLAG-CMV-14
with restriction enzymes Hind Ⅲ and BamHⅠ. The recombinant pasmid p3×FLAG-CMV-hMTERF3 were identified by colony PCR,
double restriction enzyme digest and DNA sequencing. Results:A specific band of 1 254 bp was detected from recombinant plasmid
p3×FLAG-CMV-hMTERF3 by digestion of Hind Ⅲ and BamHⅠ. The sequencing and identification showed that homology between
this sequence and the human MTERF3 gene sequence from GenBank was 100%, and the size and the direction of the inserted gene
were right. Conclusion:The eukaryotic expression vector of human MTERF3 was constructed successfully, which may lay the
foundation for a further study of the interaction mechanism between behavior of MTERF3 in tumor cells and its development.

Key words: human MTERF3, eukaryotic expression vector, identification
