核糖核酸-蛋白质(RNA-Protein,RNP)复合体在纳米技术和合成生物学领域具有广阔的应用前景。蛋白质反应RNA序列(RNP基序)可以整合到各种RNA中,如信使RNA、短发夹状RNA和用于各种目的的合成RNA纳米对象。在高分辨率下直接观察RNP在溶液中的相互作用对于RNP介导型纳米结构的设计和构建具有重要意义。在这里,我们描述了一种构建和可视化RNP纳米结构的方法,该结构可以在纳米级的RNA支架上精确地排列目标蛋白质。RNP纳米结构的高速原子力显微镜(HS-AFM)图像表明,在单一RNP分辨率下,可以直接看到定义尺寸的RNP络合物在溶液中的折叠。
RNA–protein (RNP) complexes are promising biomaterials for the fields of nanotechnology and synthetic biology. Protein-responsive RNA sequences (RNP motifs) can be integrated into various RNAs, such as messenger RNA, short-hairpin RNA, and synthetic RNA nano-objects for a variety of purposes. Direct observation of RNP interaction in solution at high resolution is important in the design and construction of RNP-mediated nanostructures. Here we describe a method to construct and visualize RNP nanostructures that precisely arrange a target protein on the RNA scaffold with nanometer scale. High-speed AFM (HS-AFM) images of RNP nanostructures show that the folding of RNP complexes of defined sizes can be directly visualized at single RNP resolution in solution.
