Figure 6. Alternative PNRC2 transcripts caused by a chimpanzee-specific ERV.

Figure 6

(A) Using the UCSC Genome Browser, the PNRC2 gene is anatomized into intron, un-translated region (UTR), and coding exon. (B) The structures of chimpanzee and non-chimpanzee primate PNRC2s and their transcripts are depicted. The black and gray boxes indicate an exon and UTRs, respectively, and the red box denotes the untranscribed UTR1 of the chimpanzee PNRC2. Four different primers used to amplify PCR products are shown in red, blue, green, and black arrows, respectively. The target site duplications (TSDs) of the full-length chimpanzee-specific ERV are written in red. (C) The picture shows an agarose gel image of PCR products. Genomic DNAs from four different primates (human, chimpanzee, gorilla, and orangutan) were used as a DNA template for each PCR reaction.
