| 摘 要： | 利用酵母双杂交技术,以百脉根离子通道蛋白Pollux胞内结构域为诱饵,从百脉根AD-cDNA文库中筛选到与Pollux相互作用的多个阳性克隆,经DNA序列测定及NCBI数据库BLAST分析,其中有6个阳性克隆编码翻译延伸因子EF1A。进一步在大肠杆菌中表达与纯化Pollux和EF1A融合蛋白,通过Pull-down及Western杂交证实Pollux胞内结构域与EF1A的C-末端相互作用。

| Abstract: | Using ion channel protein Pollux-C containing RCK domain as a bait,14 yeast colonies were screened from Lotus japonicus AD-cDNA library with yeast two-hybrid technique.Six positive clones were found to encode elongation factor 1A(EF1A) of translation through DNA sequencing and BLAST against NCBI database.The fusion tag protein of Pollux-C and EF1A expressed in E.coli were purified.The intra-cellular domain of Pollux interacted with the C-terminus of EF1A was verified by pull-down and western blotting in vitro.The results might lay a foundation for further researches on the regulating mechanism and biological function of EF1A in symbiosis signaling in legume. |
