FIGURE 8.
Structural comparison with other H3K4me3 readers. A, sequence alignment of selected CW and PHD domains. Secondary structure elements of the ZCWPW2 CW domain are indicated above the sequence alignment. The highly conserved cage “right wall” residues are marked by a red star; the other cage-forming residues are marked by blue stars or highlighted in blue. The residues recognizing H3A1 are highlighted in orange. The alignments were constructed with ClustalW (45). B, comparison of H3K4me3 binding cage in ZCWPW2 and other H3K4me3 readers' cages.
