Analysis of DNA methylation, histone acetylation, histone methylation, and CTCF binding at the Peg13 locus in mouse brains. ahESC, androgenetic haploid ESCs. P1-P4 denote the promoters of Kcnk9, Peg13, Trappc9, and Ago2, each showing distinct CTCF-binding peaks (see Figure S7B). E1 and E2 indicate enhancers located in introns 5 and 15 of Trappc9, respectively.
