1544-从头设计用于多重成像的正交荧光染料结合蛋白

from 聊聊Sci

这项研究介绍了一系列利用深度学习从头设计的蛋白质,称为Novotags,它们能以高亲和力和极强的特异性结合特定的Janelia Fluor (JF)小分子染料。通过整合蛋白质的遗传编码能力与合成染料的卓越亮度,该系统成功克服了传统荧光蛋白在光稳定性方面的局限,实现了多通道超分辨率成像。研究人员还通过调整结合口袋的电荷环境,开发出具有不同荧光寿命的变体,大幅扩展了多重成像的维度。此外,文中展示了共价结合版本以及名为Novosplit的拆分系统,后者可作为化学诱导二聚化工具或检测细胞内蛋白质近距离相互作用的生物传感器。总而言之,这项成果为分子细胞生物学研究提供了一套精密且高度可拓展的细胞成像工具箱。References:Tran L, Klein S, Juergens D, et al.
