![]() CTCF sites were relatively invariant across diverse cell types, while MYC showed the greatest cell-type specificity. CTCF bound predominantly in intergenic regions while RNAPII and MYC preferentially bound to core promoter regions. Our data and analysis revealed how these factors bind in relation to genomic features and shape gene expression and cell-type specificity. In the ENCODE Project, we have identified the genomic binding locations across 11 different human cell types of CTCF, RNA Pol II (RNAPII), and MYC, three TFs with diverse roles. However, there are few systematic studies of the genomic binding of different types of TFs across a wide range of human cell types, especially in relation to gene expression. ![]() Cell-type diversity is governed in part by differential gene expression programs mediated by transcription factor (TF) binding. ![]()
