在这里,我们提出了一个管道来映射体内蛋白质结合DNA的状态。我们的管道推断以及量化合作绑定。使用双酶单分子足迹(dSMF)数据,我们展示了我们的工作流程如何识别果蝇S2细胞中增强子的结合状态。来自缺乏内源性DNA甲基化的细胞的数据是该管道的先决条件。有关本方案使用和执行的完整详细信息,请参见和。使用dSMF数据量化DNA-蛋白质结合状态的管道该管道可以可靠地映射chomatinized DNA上的共结合事件与MNase-和DNase-seq不同,dSMF映射基因组DNA的未结合状态在这里,我们提出了一个管道来映射体内蛋白质结合DNA的状态。我们的管道推断以及量化合作绑定。使用双酶单分子足迹(dSMF)数据,我们展示了我们的工作流程如何识别果蝇S2细胞中增强子的结合状态。来自缺乏内源性DNA甲基化的细胞的数据是该管道的先决条件。
Here, we present a pipeline to map states of protein-binding DNA in vivo. Our pipeline infers as well as quantifies cooperative binding. Using dual-enzyme single-molecule footprinting (dSMF) data, we show how our workflow identifies binding states at an enhancer in Drosophila S2 cells. Data from cells lacking endogenous DNA methylation are a prerequisite for this pipeline. For complete details on the use and execution of this protocol, please refer to and.
