摘要
WD重复蛋白(WD repeat protein)家族是一类含有多个保守WD基序的蛋白.该家族蛋白广泛存在于真核细胞中,参与细胞发育、增殖和凋亡等生理过程.WDR70隶属于WD重复蛋白家族,其生物学功能目前仍不清楚.本文以人cDNA为模板扩增WDR70基因;然后以pTag2b为载体,通过同源重组构建重组质粒并进行测序.同时将质粒转染至人肺癌细胞株A549中,进行WDR70蛋白的表达分析.结果显示该重组质粒在A549细胞中能有效表达.质粒pTag2B-WDR70的成功构建为进一步研究WDR70相关生物学功能提供实验基础.
WD repeat protein is a class of proteins containing several conservative WD motif. The family of WD protein extensively exists in eukaryocytes and involved in a variety of biological process,such as cell development,proliferation and apoptosis. WDR70 belongs to WD repeat protein family. At present,the function of WDR70 is not clear. In this experiment,PCR was performed on amplification of WDR70 gene. Then we constructed p CMV-Tag2B-WDR70 recombinant plasmid by homologous recombination. The recombinant plasmid was sequenced and transfected into A549 human lung cancer cells. Finally Western blot was performed to analysis the expression of WDR70 protein. The experimental results showed that WDR70 gene was successfully cloned,and p CMV-Tag2BWDR70 recombinant plasmid was expressed efficiently in A549 cells. The construction of p CMV-Tag2B-WDR70 recombinant plasmid provides experiment materials for further reserch on WDR70-related biological functions.
