Dataset Summary
Title | Pull-down affinity purifications using di-nucleosomes decorated with enhancer-associated modifications and incorporating 200bp linker DNA |
Description | Characteristic features of chromatin states are not limited to particular epigenetic modifications but include other regulatory cues, such as linker DNA length, typically ranging from around 35-55 bp in most eu- and heterochromatin domains (Valouev et al, 2011; Voong et al., 2016, Cell) to over 200 bp in nucleosome-depleted regions (NDRs) found at active enhancers and promoters (Schones et al, 2008; Hansen He et al, 2010). To investigate whether and how nucleosome linker DNA affects chromatin recognition by nuclear proteins we performed an additional set of affinity purifications using di-nucleosomes incorporating different DNA linkers. Here, we investigated the effect of a 200 bp di-nucleosome linker DNA represented by scrambled DNA or SV40 enhancer DNA sequence on the nuclear protein binding to di-nucleosome decorated with enhancer-associated modifications, including H3K4me1 and H3K27ac. |
