摘　　要：核基质结合蛋白SATB1调控染色质的空间结构,参与真核生物基因表达。本论文通过PCR获得SATB1目的基因,然后与载体mCherry-C1同时用EcoRⅠ和KpnⅠ双酶切后,用T4连接酶进行连接。连接质粒转入感受态宿主细胞并在Kana抗性的LB培养基中培养。分离获得Kana抗性单克隆菌株并进行扩大培养后提取重组质粒。对重组质粒进行双酶切验证和DNA测序检测。本论文成功构建mCherry-SATB1真核表达质粒,为后续研究SATB1的功能机制奠定基础。Nuclear matrix binding protein SATB1 participates in eukaryotic gene expression by regulating the spatial structure of chromatin.In this study,the SATB1 gene fragment was amplified by PCR.The PCR product and mCherry-C1vector were digested with EcoRⅠand KpnⅠ,and then connected with T4 ligase.The constructed plasmid was transferred into competent host cells DH5αand cultured on Kana+LB medium,and the single colony was selected and cultured.The constructed plasmid was verified by double enzyme digestion and DNA sequencing.It is proved that the eukaryotic expression plasmid mCherry-SATB1 was successfully constructed and can be used for further research of SATB1 function.
