RNA -蛋白相互作用控制病毒RNA复制、转录、翻译和颗粒组装。由于缺乏高分辨率的结构信息,了解rna -蛋白复合物在病毒生命周期中的功能意义的进展受到阻碍。获取结构数据的挑战包括RNA固有的不稳定性和构象可塑性,以及为生物物理实验生成大量RNA的相对较高的成本。通过进行生物化学实验,确定相互作用域和识别关键残基,成功确定结构的可能性增加。这些方法旨在定义和表征适合高分辨率结构分析的RNA和蛋白质底物。
RNA–protein interactions control viral RNA replication, transcription, translation, and particle assembly. Progress toward understanding the functional significance of RNA–protein complexes in the viral life cycle is hindered by the lack of high resolution structural information. Challenges to acquiring structural data include RNA's inherent instability and conformational plasticity, coupled with the comparatively high cost of generating large quantities of RNA for biophysical experiments. The potential for successful structure determination is increased by conducting biochemical experiments that outline interacting domains and identify key residues. These approaches are aimed at defining and characterizing RNA and protein substrates that are suitable for high resolution structural analysis.
