简介


       RNA Immunoprecipitation SequencingRNA免疫沉淀与高通量测序结合的技术,也叫RIP-seqRIP-seq能够绘制了蛋白质与RNA-蛋白质复合物中的RNA结合的位点或区域。在这种方法中,RNA-蛋白质复合物与靶向感兴趣蛋白质的抗体进行免疫沉淀。RNase消化后,提取受蛋白质结合保护的RNA并逆转录为cDNA。然后可以将这些位置Mapping到基因组上。对RIP下来的RNA片段反转录成cDNA,构建测序文库进行后续的RNA结合蛋白相关结合位点信息分析。


       与ChIP-seq不同点在于,RIP-seq研究主要是RNA结合蛋白(RNA binding protein, RBP)靶向RNA的信息。而ChIP-seq主要聚焦在部分DNA结合蛋白如转录因子以及组蛋白等靶向的DNA序列信息。








应用场景与案例


应用场景1RNA结合蛋白靶基因研究

RNA结合蛋白(RNA binding protein, RBP)是指一类伴随RNA的调控代谢过程与RNA结合的蛋白质的总称。利用RIP-seq可以对RBP结合的所有靶基因在全转录/全基因层面进行全局扫描,锁定后续感兴趣的靶基因。
