(H) ChIP-seq analysis of DAXXMycHis occupancy in HEK2935xUAS cells expressing DAXXMycHis (X-axis) versus GAL4DBDCBX2.1 and DAXXMycHis (Y-axis) showing strong enrichment (log2) for DAXXMycHis at many TSSs of genes, but only when both proteins are expressed (Y-axis), indicating that CBX2.1 targets DAXX to chromatin. TSSs highlighted in red show enrichment with anti-Myc antibody independently of GAL4DBDCBX2.1 occupancy.
