针对RNA位点的分子工具允许对RNA信息和处理进行重新编码。Snap标记的脱氨酶在化学稳定的引导RNA的指导下,能够同时编辑几个内源转录本中的靶向腺苷为肌苷,具有高效率(高达90%)、高效力、足够的持续时间和高精度。我们应用SNAP-ADAR高效和同时编辑两个与疾病相关的信号转录本,KRAS和STAT1。我们还显示,与最近描述的Cas13b-ADAR相比,性能有所改善。
Molecular tools to target RNA site-specifically allow recoding of RNA information and processing. SNAP-tagged deaminases, guided by a chemically stabilized guideRNA, enable the simultaneous editing of targeted adenosine to inosine in several endogenous transcripts, with high efficiency (up to 90%), high potency, sufficient duration, and high precision. We applied SNAP-ADARs for the efficient and concurrent editing of two disease-relevant signaling transcripts, KRAS and STAT1. We also show improved performance compared to the recently described Cas13b-ADAR.
