[Abstract]  We have developed locus-specific chromatin immunoprecipitation (locus-specific ChIP) technologies consisting of insertional ChIP (iChIP) and engineered DNA-binding molecule-mediated ChIP (enChIP). Locus-specific ChIP is a method to isolate a genomic region of interest from cells while it also identifies what binds to this region using mass spectrometry (for protein) or next generation sequencing (for RNA or DNA) as described in Fujita et al. (2016a). Recently, we identified genomic regions that physically interact with a locus using an updated form of enChIP, in vitro ... [摘要]  我们开发了基因座特异性染色质免疫沉淀(基因座特异性芯片)技术,包括插入ChIP(iChIP)和工程DNA-结合分子介导ChIP(enChIP)。 基因座特异性ChIP是一种从细胞中分离感兴趣的基因组区域的方法,同时它还使用质谱(用于蛋白质)或下一代测序(用于RNA或DNA)鉴定什么与该区域结合,如Fujita等人 (2016a)。 最近,我们使用更新后的enChIP形式,结合NGS( in vitro enChIP-Seq),鉴定了与基因座物理相互作用的基因组区域(Fujimita et al。,2017a)。 在这里,我们描述了一个体外试验的方法,用于分离靶基因座以鉴定与基因座物理相互作用的基因组区域。
【背景】阐明基因组功能强调的分子机制需要鉴定与感兴趣的基因组区域相互作用的分子。为此,我们开发了由插入ChIP(iChIP)和工程化DNA结合分子介导的ChIP(enChIP)组成的基因座特异性染色质免疫沉淀技术(基因座特异性ChIP)技术(Fujita等人 ...

[Abstract]  This protocol describes the extraction of RNA-binding proteins (RBPs) from cell lysates. In order to pull down target RBPs, 5-bromo-UTP (BrUTP)-incorporated RNA probes are used, which are generated by in vitro transcription. The schematic diagram (Flowchart) with procedure is indicated (Figure1 and Figure 2).

[Abstract]  Elucidation of molecular mechanisms of genome functions requires identification of molecules interacting with genomic regions of interest in vivo. To this end, it is useful to isolate the target regions retaining molecular interactions. We established locus-specific chromatin immunoprecipitation (ChIP) technologies consisting of insertional ChIP (iChIP) and engineered DNA-binding molecule-mediated ChIP (enChIP) for isolation of target genomic regions (Hoshino and Fujii, 2009; Fujita and Fujii, 2011; Fujita and Fujii, 2012; Fujita and Fujii, 2013a; Fujita and Fujii, 2013b; Fujita et ... [摘要]  阐明基因组功能的分子机制需要在体内鉴定与感兴趣的基因组区域相互作用的分子。为此,分离保持分子相互作用的靶区是有用的。我们建立由插入ChIP(iChIP)和工程化的DNA结合分子介导的ChIP(enChIP)组成的基因组特异性染色质免疫沉淀(ChIP)技术用于靶基因组区域的分离(Hoshino和Fujii,2009; Fujita和Fujii,和Fujii,2012; Fujita和Fujii,2013a; Fujita和Fujii,2013b; Fujita等人,2013)。与分离的基因组区域相互作用的分子的鉴定和表征有助于理解靶基因组区域的功能的分子机制。在这里,我们描述enChIP,其中工程化的DNA结合分子,如锌指蛋白,转录激活样(TAL)蛋白和催化失活的Cas9(dCas9)加上小指南RNA(gRNA),被用于亲和纯化靶基因组区。 enChIP的方案如下所示:
1。产生锌指蛋白,TAL或dCas9加gRNA以识别感兴趣的基因组区域中的DNA序列。
2。工程化的DNA结合分子与标签和核定位信号(NLS)融合,并在待分析的细胞中表达。如果需要,所得细胞被交联,并裂解,DNA被片段化。将包括工程化DNA结合分子的复合物进行亲和纯化,例如免疫沉淀。分离的复合物保留分子与感兴趣的基因组区域相互作用。 ...
