Transcription factor binding site (TFBS) prediction in the IGF2 promoter regions. a Total predicted transcription factors involving the four CpG sites in the promoter of IGF2 gene. The red arrows represent the distribution of the CpG loci. b The partial predicted transcription factors related to −587 and −575 CpG sites and the same as below. c, d and e are correlated with −575 and −566 CpG sites, −566 CpG site and −527 CpG site respectively. Contents in the boxes describe detailed information of transcription factors which might combine the region containing the CpG sites
