Figure 5. Schematic representations of H19/IGF2. DNA methylation interactions of H19 DMD and IGF2 DMRs on the maternal (A) and paternal allele (B) in the male eye. The specific chromatin structure is described on the maternal (C) and paternal allele (D) in the female eye. As expected, the specific chromatin structures are established as in parthenogenetic (PA) cells (E and F). Ex: exon; E: enhancer; Red dotted line: active domain; CTCF: CCCTC-binding factor - binding sites; PPF: putative protein factors.
