DAP-seq(DNA亲和纯化测序),成功将体内结合实验转移到体外,解决了ChIP抗体制备的困扰,极大的提高 DNA Binding Site发现的效率。 DAP-seq不仅能够超高通量查找TFBS,还能深入了解众多TF的生物学特性和结合位点结构,在任何有机体的顺反和表观研究中表现出巨大的价值。
This interaction occurred at a site(s) between 410 and 795 (Cavanaugh and Simons, 1993). A much larger factor (130,000 Mr) has also been found to increase the amount of DNA binding by six-fold in gel shift assays (Kupfer et al., 1993). Because of the qualitative nature of gel ...
Identification of amino acid residues involved in DNA binding site is critical for understanding of the mechanism of gene regulations. In the last decade, there have been a number of computational approaches developed to predict protein-DNA binding sites based on protein sequence and/or structural ...

A total of 9,027 CDF2 binding peaks were identified and associated with 12,308 neighbouring genes (Supplementary information, Extended Data Fig. 3a and Supplementary Table 1). The majority (81.6%) of the peaks were within 3 kb of sequence 5′ to the transcription start site of a gene ...
(K) residues) that interact with negatively charged DNA could reduce the DNA-binding affinity of DddAtox(Supplementary information, Fig.S1), potentially decreasing off-target editing activity. Based on the solved three-dimensional (3D) structure of DddAtox3(Fig.1a), we identified five such ...
转录因子的结合位点(transcription factor binding site,TFBS)是转录因子调节基因表达时,与mRNA结合的区域.按照常识,转录因子(transcription factor,TF)的结合位点一般应该分布在基因的前端,但是,新的研究发现,人21和22号染色体上,只有22%的转录因子结合位点分布在蛋白编码基因的5'端. 这篇文章的试验方法是,通过高密度...
predicting the fraction of H-DNA, indicating that the association of H-DNA is a concerted process. The association/dissociation free energy change is more appropriate than the binding constant, for characterizing the binding affinity between ligands and the DNA binding site. The experimental and ...
将异源DNA结合位点Gal4DNA结合域融合到全长基因当中,并将下面的activator-binding site替换为Gal4-binding site 对蛋白进行删除,看看它对转录激活产生了什么影响,这里我们观察的是βGal的活性,如果发生激活,会产生多个+,图中黄色方框圈出的是蛋白的激活域
② DNA的PDB文件导入之后,加氢去水之后,不用准备蛋白,因为他不是蛋白,直接设置对接盒子即可。receptor ligand interaction-define and edit binding site,选中ligands之后,点击左栏From current selection,然后出现一个虚线的球,点一下变成实心的之后,可以选择expand和contract。
