Project description:Chromatin immunoprecipitation followed by massively parallel sequencing (ChIP-seq) is a powerful approach to identify the genome-wide localization of protein of interest. However, to perform ChIP-seq experiments for large protein complex, such as Mi-2/NuRD complex, is still challenging. Here, we present high-quality MBD3 ChIP-seq data in human breast cancer cells, MDA-MB-231. MBD3 ChIP-seq experiment was perform using human breast cancer cells, MDA-MB-231. Two bilogical replicates were prepared.

Project description:Maintenance of chromatin structure is essential to eukaryotic life; dysregulation is known to be causal for aberrant development and disease. The Mi-2/nucleosome remodeling and histone deacetylase (NuRD) complex is a multiprotein machine proposed to regulate chromatin structure by nucleosome remodeling and histone deacetylation activities. We identified the localization of MBD3, a component of Mi-2/NuRD complex, in two breast cancer cell lines (MCF7 and MDA-MB-231) using ChIP-Seq. MBD3 showed cell-type specific localization with overlap across cell lines being less than 50%. MBD3 localized across gene bodies, peaking around the transcription start site (TSS). Contrary to existing models, MBD3 preferentially associated with CpG rich promoters marked by H3K4me3. These data suggest that MBD3, and by extension the Mi-2/NuRD complex, may have roles in fine tuning expression for active genes. These data represent an important first step in defining regulatory mechanisms by which Mi-2/NuRD complex controls chromatin structure and gene expression.
