Characterization of the transcription unit for IGF2 in Monodelphis domestica . A) Genomic map of the M. domestica IGF2 gene. The scale bar is indicated and the key to the annotation, which includes coding exons, the 5' noncoding exon, the MAR predicted by MAR-Wiz and CpG islands predicted by CpG Plot, is shown below. B) & C) Evolutionary conserved segments within the M. domestica IGF2 locus. VISTA pairwise comparisons showing conserved segments between M. domestica and B) Macropus eugenii, C) Homo sapiens. Percent homology is indicated on the Y-axis and the position and size of regions of high homology are indicated on the X-axis in kilobases according to the reference sequence (M. domestica). Arrows denote the four exons in M. domestica. Black bars indicate >50% identity, light blue bars indicate >75% identity, dark blue bars indicate >80% identity, pink bars indicate >85% identity, and red bars indicate >90% identity.
