为筛选人脑cD N A文库中与狂犬病病毒基质蛋白(M 蛋白)具有相互作用的蛋白基因,并对阳性克隆进行初步的分析和鉴定。首先构建了含有M 基因的诱饵质粒pGBK T7-CVS11-M ,并对其进行自激活和毒性检测,然后采用酵母双杂交技术初步筛选出与M 蛋白具有相互作用的12个阳性克隆,对阳性克隆进行PC R鉴定及测序分析,并通过酵母回复性试验最终获得3个无重复性克隆,编码的蛋白质分别为TAB2、P4HA2和RCN1。为研究狂犬病病毒M 蛋白在致病机制中的作用提供了参考。
為篩選人腦cD N A文庫中與狂犬病病毒基質蛋白(M 蛋白)具有相互作用的蛋白基因,併對暘性剋隆進行初步的分析和鑒定。首先構建瞭含有M 基因的誘餌質粒pGBK T7-CVS11-M ,併對其進行自激活和毒性檢測,然後採用酵母雙雜交技術初步篩選齣與M 蛋白具有相互作用的12箇暘性剋隆,對暘性剋隆進行PC R鑒定及測序分析,併通過酵母迴複性試驗最終穫得3箇無重複性剋隆,編碼的蛋白質分彆為TAB2、P4HA2和RCN1。為研究狂犬病病毒M 蛋白在緻病機製中的作用提供瞭參攷。

In this study ,a human brain cDNA library was screened to identify rabies virus matrix protein (M protein) interaction partners ,and the positive clones were preliminarily identified .The bait plasmid pGBKT7-CVS11-M was constructed successfully and tested for auto-activation and toxicity and then was used to screen the proteins interacting with M protein in a yeast two-hybrid assay .Twelve positive clones were obtained .Subsequently ,they were verified by PCR and sequencing analysis ,and further conformed by retransformation assay .Three final positive proteins were verified as interacting proteins with M pro-tein through retransformation assay in yeast cells ,which were TAB2 ,P4HA2 and RCN1 .The research will contribute to explore the function of M protein at molecular level ,which would provide important clues for studying the pathogenic mechanism of rabies virus .
