Figure 2. Methylation status of CpG islands in PPP1R26 and its retrocopies.

Figure 2

The CpG islands in the 5’-part of exon 4 studied for PPP1R26 and its retrocopies on chromosome 22 and 8 are fully methylated. Only the retrocopy in intron 2 of the RB1 gene (orangutan shows differential methylation only at some CpG sites) and the additional retrocopy on chromosome 4 in marmoset show differential methylation. red, methylated; blue, unmethylated. Blood sample IDs are given under the images (C1, C2 - human; 1014, 1126 - chimpanzee; 518, 519 - orangutan; 45, 46 - rhesus macaque; FC49, 15100 - marmoset; O2013 - galago).
