摘要
目的:构建带Myc标签的LC3B-PLA2基因的真核表达质粒,获得LC3B-PLA2融合蛋白,并应用LC3B-PLA2研究Atg4B对LC3B的切割作用。方法:以本实验室保存的乳腺文库为模板,PCR扩增获得LC3B序列,与PLA2G10拼接后插入pCMV-Myc载体,用构建的重组质粒转染HEK293T细胞,Western印迹检测融合蛋白的表达,用LC3B-PLA2与Atg4B共转染的方法检测Atg4B对LC3B的切割作用。结果:菌液PCR、重组质粒双酶切及测序均表明重组质粒构建成功,Western印迹结果表明融合蛋白在HEK293T细胞中获得表达,LC3B-PLA2真核表达蛋白能够应用于Atg4B对LC3B切割作用的研究。结论:构建了pCMV-Myc-LC3B-PLA2真核表达质粒,LC3B-PLA2融合蛋白在Atg4B对LC3B切割作用的研究中至关重要,为进一步研究Atg4B在自噬过程中的作用奠定了基础。
