近年来,荧光蛋白的发现和应用极大地拓展了分子和细胞生物学的研究领域。这些光开关蛋白促进了细胞中特异性标记分子物种的表征,并使细胞内结构的荧光成像分辨率远低于经典的光衍射极限。然而,由于目前可用的可切换蛋白的快速光漂白、缓慢光开关和低聚化,其应用受到限制。在这里,我们报道了mKikGR的分子克隆和光谱表征,mKikGR是先前报道的KikGR的单体版本,具有较高的光稳定性和开关速率。此外,我们提出的单分子成像实验表明,单个mKikGR蛋白可以定位精度优于10纳米,这表明它们适合超分辨率成像。
The recent demonstration and utilization of fluorescent proteins whose fluorescence can be switched on and off has greatly expanded the toolkit of molecular and cell biology. These photoswitchable proteins have facilitated the characterization of specifically tagged molecular species in the cell and have enabled fluorescence imaging of intracellular structures with a resolution far below the classical diffraction limit of light. Applications are limited, however, by the fast photobleaching, slow photoswitching, and oligomerization typical for photoswitchable proteins currently available. Here, we report the molecular cloning and spectroscopic characterization of mKikGR, a monomeric version of the previously reported KikGR that displays high photostability and switching rates. Furthermore, we present single-molecule imaging experiments that demonstrate that individual mKikGR proteins can be localized with a precision of better than 10 nanometers, suggesting their suitability for super-resolution imaging.
