Figure 2

Exon map of the embryonic T1 (A) and T2 (B) transcripts. The T1 and T2 transcripts shown were derived by a combination of direct standard RT-PCR (transcripts designations with the "RT" prefix), 3'-extended RT-PCR (XT-tagged transcripts) and RACE experiments (transcripts T1E16-A and -B) as described in the text. For identical T1 or T2 transcripts derived from the various experimental approaches, only a representative transcript designation is used. Included as a reference is the testicular T1 and T2 exon map that was previously derived [20]. Exons are represented by coloured blocks and the exon designations are shown above the testicular transcripts. The coding sequences (CDS) of T1 and T2 are shown as white boxes. An, polyA tract. Alternative 5'-splice sites (5'ss) are indicated. At the bottom of the T1 and T2 transcript panels, the elucidated transposable element sequences are displayed aligning with the corresponding exon of the transcripts. L1, LINE1 sequence; ERV, endogenous viral sequence; S1, SINE1 sequence; hAT, DNA transposon. T1E16-A and -B are now filed as GenBank:FJ004892 and GenBank:FJ004893, respectively. The scheme is not drawn to scale.
