| 摘 要： | 从重组克隆载体pMD18-T—egsmadC中扩增细粒棘球蚴egsmadC基因及其MH2编码序列，将其克隆入酵母双杂交载体pGADT7和pGBKT7中，经PCR、限制性酶切鉴定及序列测定正确后，PEG／LiAe法转化酵母菌株，测定融合蛋白对酵母菌生长的影响和自激活活性。结果表明，egsmadC基因及其MH2编码序列表达的蛋白对酵母茵Y2HGold无毒性和自激活作用，可为进一步运用酵母双杂交技术筛选与之相互作用的蛋白奠定基础。 |

| Abstract: | The complete encoding gene of egsmadC and egsmadC-MH2 from Echinococcos granulosus(Eg) was amplified in the recombinant plasmid pMD18-T-egsmadC by PCR and they were then subcloned into MCS of pGADT7 and pGBKT7 vectors,respectively.After being verified by PCR,restriction analysis and sequencing,the recombined plasmids were transformed into the yeast strain Y2HGold by PEG/LiAc method and their toxicity and self-activation were detected.This result means that the yeast two-hybrid expression vectors of egsmadC and egsmadC-MH2 were constructed successfully and would not toxicity and self-activation,which lays the foundations for screening the egsmadC-interacting proteins using the yeast two-hybrid technique. |
| Keywords: | smadC gene MH2 domain yeast two-hybrid system self-activation |
