[Abstract]  Digestion of chromatin by micrococcal nuclease MNase followed by high throughput sequencing allows us to determine the location and occupancy of nucleosomes on the genome. Here in this protocol we have described optimized conditions of MNase digestion of filamentous fungus Neurospora crassa chromatin without a requirement of a nuclear fractionation step. [摘要]  通过微球菌核酸酶MNase消化染色质,然后高通量测序允许我们确定核小体在基因组上的位置和占据。 在这个协议中,我们描述了MNase消化丝状真菌粗糙链孢霉染色体的优化条件,而不需要核分馏步骤。

Chromatin Immunoprecipitation (ChIP) Assay for Detecting Direct and Indirect Protein – DNA Interactions in Magnaporthe oryzae

[Abstract]  Chromatin immunoprecipitation (ChIP) is a powerful technology for analyzing protein-DNA interactions in cells. Robust ChIP procedures have been established for investigating direct interactions between protein and DNA. However, detecting indirect protein-DNA interactions in vivo is challenging. Recently, we used ChIP to analyze an indirect protein-DNA interaction between a putative histone demethylase, MoJmjC, and the promoter of the superoxide dismutase 1-encoding gene MoSOD1 in the rice blast fungus Magnaporthe oryzae (M. oryzae) (Fernandez et al., 2014). We tagged MoJmjC with the 3x FLAG epitope (Fernandez et al., 2014), instead of the larger and more commonly used GFP epitope, to mitigate against steric hindrance. We also employed ... [摘要]  染色质免疫沉淀(ChIP)是一种强大的技术,用于分析细胞中的蛋白质-DNA相互作用。已建立了稳健的ChIP程序用于研究蛋白质和DNA之间的直接相互作用。然而,在体内检测间接蛋白-DNA相互作用是具有挑战性的。最近,我们使用ChIP来分析推定的组蛋白去甲基化酶MoJmjC和在稻瘟病真菌Magnaporthe oryzae中超氧化物歧化酶1编码基因MoSOD1的启动子之间的间接蛋白质-DNA相互作用( oryzae )(Fernandez ,,2014)。我们用3x FLAG表位标记MoJmjC(Fernandez等人,2014),而不是更大和更常用的GFP表位,以减轻空间位阻。我们还采用了使用DSG和甲醛的两步交联策略,而不是更常用于分析直接蛋白质-DNA相互作用的一步甲醛交联方法,以便更好地捕获间接的MoJm - MoSOD1 DNA相互作用。此外,我们已经表明两步交联适用于GATA转录因子,Asd4及其同源结合位点之间的直接蛋白-DNA相互作用的ChIP分析(Marroquin-Guzman和Wilson,2015)。在这里,我们提供详细的协议的染色质免疫沉淀,与通用的两步交联,在M。 oryzae 。
