摇摆碱基提高了 RNA 编辑的精确度
内源性人类 ADAR 酶被用来进行腺苷酸-肌苷酸(A-to-I)编辑,其中肌苷酸在碱基配对中类似于鸟苷酸(G),从而实现最终的 A-G 编辑。为了实现有针对性的编辑,引导 RNA 被设计成与目标 RNA 形成双链 RNA 结构,为 ADAR 招募创建一个位点。"只需施用一种成分,即 RNA。德国图宾根大学的 Thorsten Stafforst 解释说。斯塔福斯特小组对 RNA 编辑有着长期的兴趣,并在该领域开发了各种工具。然而,RNA 碱基编辑的一个主要挑战是旁观者编辑事件--对目标位点附近的 A 进行意外编辑,可能导致有害的重编码事件。为了解决这个问题,有人介绍了结合尿苷去除和 G-A 错配的引导 RNA 设计,以减少旁观者编辑。尽管有了这些改进,但一种既能消除旁观者编辑,又能保持编辑效率的普遍有效的方法仍遥遥无期。
