Figure 4

Members of the new teleost specific SLC1 subfamilies show changes in coding sequence length and exon size. Analysis of the last two exons within the slc1a2/9 (A) and slc1a7/8 (B) subfamilies reveals an altered exon size and coding sequence length. While the coding sequence encoded by the last two exons of the slc1a9 gene are longer than the corresponding coding sequence of the slc1a2 family, exons of the members of the slc1a8 subfamily have a shorter coding sequence. Changes within the new subfamilies are highlighted in bold. Note that only Danio rerio genes are shown, but that the exon alignment of other teleost fish species gave comparable results.
