中文摘要
作用于基因组DNA的蛋白质在功能上调节基因组。因此,如果我们能够全面揭示基因组DNA和活细胞中蛋白质之间的相互作用,我们将大大加深对基因组如何工作的理解。作为实现这一目标的一种新方法,我们试图开发一种名为DMS-Seq的方法,它使用二甲基硫酸盐(DMS)和下一代测序。在对方法进行优化后,我们将其应用于面包师酵母作为模型系统,并成功地检测到了已知调控基因表达的区域的信号。这些结果表明了这种方法的可行性。
英文摘要
Proteins that act on genomic DNA functionally regulate the genome. Accordingly, if we can comprehensively reveal the interactions between genomic DNA and proteins in living cells, we will substantially deepen our understanding of how the genome works. As a novel method toward this goal, we tried to develop a method termed DMS-Seq that uses dimethylsulfate (DMS) and next-generation sequencing. Following the optimization of the method, we applied it to the baker's yeast as a model system and successfully detected signals on regions known to regulate gene expression. These results would suggest the feasibility of this approach.
