Here, we developed a reverse transcriptase based method (RTase stop assay) to characterize quadruplex formations in guanine-rich RNAs with high sensitivity and specificity. By using the RTase stop assay, we also revealed a plausible structural polymorphism in biologically important RNAs. The RTase stop assay would provide helpful insight into RNA quadruplex structures and functions, together with other analytical methods, including various footprinting techniques.
在这里,我们开发了一种基于逆转录酶的方法(RTase 停止分析),以高灵敏度和特异性来表征富含鸟嘌呤的 RNA 中的四链体形成。通过使用 RTase 停止分析,我们还揭示了生物重要 RNA 中一种可能的结构多态性。RTase 停止分析将与其他分析方法一起,包括各种足迹技术,为 RNA 四链体结构和功能提供有帮助的见解。
