Photoactivatable-Ribonucleoside-Enhanced Crosslinking and Immunoprecipitation (PAR-CLIP) in combination with next-generation sequencing is a powerful method for identifying endogenous targets of RNA-binding proteins (RBPs). Depending on the characteristics of each RBP, key steps in the PAR-CLIP procedure must be optimized. Here we present a comprehensive step-by-step PAR-CLIP protocol with detailed explanations of the critical steps. Furthermore, we report the application of a new PAR-CLIP data analysis pipeline to three distinct RBPs targeting different annotation categories of cellular RNAs.
光激活核糖核苷增强交联与免疫沉淀技术(PAR-CLIP)结合新一代测序技术是一种用于鉴定RNA结合蛋白(RBP)内源性靶点的强大方法。根据每个RBP的特性,必须优化PAR-CLIP程序中的关键步骤。在此,我们提供了一份全面的PAR-CLIP分步方案,并对关键步骤进行了详细解释。此外,我们报告了一种新的PAR-CLIP数据分析流程在针对细胞RNA不同注释类别的三种不同RBP上的应用。
