Predicted exon–intron structure of the four new vertebrate genes of group 3. Exons are indicated by solid boxes or solid arrows (last exon). Shaded boxes indicate regions with significant homology to entries of the dbEST library. Letters above solid boxes show whether exons have been predicted by XGRAIL (g), FGENES (f), by both (gf), or by neither (−) of these two gene prediction programs.
