摘要
目的制备TTF-1相关蛋白26(TAP26)的3个磷酸化位点(S48,S66和T219)的突变体(TAP26(S48→A48)、TAP26(S66→A66)和TAP26(T219→V219))。方法采用定点诱变PCR技术,分别突变掉TAP26的3个磷酸化位点(S48,S66和T219),并获得TAP26的3个相应突变体。结果DNA序列分析结果显示TAP26的3个突变体序列正确。结论通过定点诱变PCR技术,成功构建了TAP26的3个突变体。
Objective To prepare 3 phosphorylation site (S48, S66 and T219) mutants of TTF-1 associated protein 26 (TAP26) E TAP26 ( S48→A48 ), TAP26 (S6→A66) and TAP26 (T219→V219) 3 . Methods Site-directed mutagenesis PCR was employed to eliminate 3 phospho- rylation sites (S48,S66 and T219) of TAP26, respectively, and generate 3 mutants. Results DNA sequence analysis revealed 3 mutant TAP26 with correct sequence. Conclusions Three phos- phorylation site mutants of TAP26 were successfully constructed by site-directed mutagenesis PCR.
