[Abstract]  Ribonucleoprotein particles (mRNPs) are complexes consisting of mRNAs and RNA-binding proteins (RBPs) which control mRNA transcription localization, turnover, and translation. Some mRNAs within the mRNPs have been shown to undergo degradation or storage. Those transcripts can lack general mRNA elements, like the poly(A) tail or 5’ cap structure, which prevent their identification through the application of widely-used approaches like oligo(dT) purification. Here, we describe a modified cross-linking affinity purification protocol (cCLAP) based on existing cross-linking and immunoprecipitation (CLIP) methods to isolate mRNAs which could be deadenylated, decapped and/or partially degraded in mRNPs, opening the possibility to detect different types of non-coding RNAs (ncRNAs). Once isolated, ... [摘要]  核糖核蛋白颗粒(mRNP)是由mRNA和RNA结合蛋白(RBP)组成的复合物,其控制mRNA转录定位,转换和翻译。已显示mRNP内的一些mRNA经历降解或储存。那些转录物可能缺乏一般的mRNA元件,如poly(A)尾或5'帽结构,这通过应用广泛使用的方法如oligo(dT)纯化来阻止它们的鉴定。在这里,我们描述了基于现有的交联和免疫沉淀(CLIP)方法的修饰的交联亲和纯化方案(cCLAP),以分离mRNP中可被去腺苷酸化,去除和/或部分降解的mRNA,从而开启了检测不同的可能性。非编码RNA(ncRNA)的类型。分离后,将RNA进行衔接子连接,然后进行下一代测序(NGS)。由于快速有效的交联和淬灭步骤,该方案也适用于瞬时诱导的mRNP颗粒。实例包括由外在应激物触发的处理体(PB)或应力颗粒(SG)。其重现性和广泛应用使该方案成为研究特定RNP的RNA组成的有用且有力的工具。
【背景】mRNP内转录物的表征对于理解细胞转录和转录后过程至关重要。通过交联和免疫沉淀,然后通过RNA-Seq从mRNP颗粒中分离RNA已经成为鉴定mRNA靶标的常用方法(Tagwerker et al。,2006; Hafner et al。,2010; Kishore et al。,2011)。 ...

[Abstract]  RNA editing is a widespread post-transcriptional phenomenon through which primary RNA sequences are altered by nucleotide insertion/deletion or base conversion. It occurs in a variety of organisms and cooperates with alternative splicing in increasing both proteomic and transcriptomic complexity. We describe here a method allowing RNA editing events detection by performing direct sequencing of both genomic DNA and cDNA from the same source. [摘要]  RNA编辑是广泛的转录后现象,通过其通过核苷酸插入/缺失或碱基转化来改变初级RNA序列。 它发生在多种生物体中,并与增加蛋白质组和转录组复杂性的可变剪接协作。 我们在这里描述一种允许通过对来自相同来源的基因组DNA和cDNA进行直接测序来进行RNA编辑事件检测的方法。
