我们将单分子荧光共振能量转移(smFRET)与活细胞中的单粒子追踪相结合,以检测单个蛋白质的体内构象。我们用 FRET 供体和受体对重组 SNARE 蛋白进行位点特异性标记,然后将其显微注射到培养细胞中。我们观察到单个蛋白质快速整合到细胞膜上的折叠复合物中,证明了该方法揭示细胞内动态相互作用的潜力。
We combined single molecule fluorescence resonance energy transfer (smFRET) with single particle tracking in live cells to detect the in vivo conformation of individual proteins. We site-specifically labeled recombinant SNARE proteins with a FRET donor and acceptor before microinjecting them into cultured cells. We observed that individual proteins rapidly incorporated into folded complexes at the cell membrane, demonstrating the potential of this method to reveal dynamic interactions within cells.
