Molecular organisation of the gene tra-2 of S. ocellaris (A) and B. coprophila (B) and their transcripts. Exons (boxes) and introns (dotted lines) are not drawn to scale. The colours in the scheme showing the molecular organisation of the gene and in the schemes corresponding to the different mRNA isoforms indicate the 5'- and 3'-UTR regions (in garnet), the protein coding exons (in green) and the specific exon in one of the mRNA isoforms (see text) (in orange). The colours in the scheme showing the proteins designate the RS1 and RS2 domains (in blue) and the RRM domain (in brown). The numbers inside the boxes indicate the number of the exon, while numbers within parenthesis indicate the number of nucleotides composing the exons and introns. The beginning and the end of the ORF are indicated by ATG and TAA respectively. AAA stands for poly-A(+). The arrow indicates the transcription initiation site. RS1, RS2 and RRM denote the corresponding domains of the putative Tra-2 protein.
