- 摘要:
- 本实验室通过疫霉菌诱导大豆绥农10 号后,获得差异表达蛋白点,通过序列拼接比对和分析,获得一个新的大豆GmDRR 基因,并通过酵母双杂筛选文库的方式获得其互作基因GmDIP1。为进一步明确两个基因关系,对两个基因分别进行亚细胞定位和原核表达以及重组蛋白的纯化。GmDRR 蛋白为外分泌蛋白,定位于细胞膜与细胞质中,GmDIP1 基因定位于线粒体膜上,二者都成功进行了原核表达,从而获得了有表达功能和生物学活性的蛋白。
- Abstract:
- A differentially expressed protein was separated from soybean Suinong 10 induced by Phytophthora sojae in the previouswork of our lab. A new gene GmDRR was obtained by sequence alignment,comparison and analysis. Then its interactiongene GmDIP1 was screened from cDNA library by yeast two-hybrid. To make sure the interatction relationship,subcellular localizationand prokaryotic expression of the two genes were designed and the recombinatnt proteins were purified. GmDRR is aexocrine protein,positioning in the cell membrane and cytoplasm. GmDIP1 locates on the mitochondrial membrane. Bothgenes successfully expressed in prokaryotic,thus the proteins with expression function and biological activity were obtained.
