通过胞苷(C)到尿苷(U)的转换进行的RNA编辑经常发生在陆地植物线粒体和质体中。靶胞苷被核编码的五肽重复序列(PPR)蛋白以序列特异性方式特异性识别。在藓类小立碗藓中,所有的PPR编辑因子在C-末端具有DYW-脱氨酶结构域。在这里,我们描述了cDNA的直接测序方法,以检测RNA编辑事件和RNA电泳迁移率变动分析(REMSA),以分析PPR编辑因子与其靶RNA的特异性结合。
RNA editing by cytidine (C) to uridine (U) conversions frequently occurs in land plant mitochondria and plastids. Target cytidines are specifically recognized by nuclear-encoded pentatricopeptide repeat (PPR) proteins in a sequence-specific manner. In the mossPhyscomitrella patens, all PPR editing factors possess the DYW-deaminase domain at the C-terminus. Here, we describe methods for the direct sequencing of cDNA to detect RNA editing events and the RNA electrophoresis mobility shift assay (REMSA) to analyze the specific binding of PPR editing factors to their target RNA.
