Fig 4. Exon-intron structure of the Ccnb1ip1 gene in the JF1 and C57BL/6 genomes.

Fig 4

RT-PCR products from exon 1 to exon 5 were detected in an E9.5 embryo of JF1. Exon 1 of Ccnb1ip1 was located in the vicinity of the Ccnb1ip1 insulator (red box) and enhancer (blue box) in the JF1 genome. The sequences corresponding to exon 2 and exon 4 of the Ccnb1ip1 gene were found to be present, but those corresponding to exon 1 and exon 3 to be absent (deleted) in the B6 genome. The horizon bars (1 to 7) indicate genomic regions for which DNA methylation statuses were assessed (Fig 1).
