Open reading frame organization in the eyg genes of Drosophila and Tribolium. The comparison between experimentally confirmed transcript sequences shows that all introns in the coding regions of Drosophila and Tribolium eyg homologs are conserved except for the acquisition of a new intron in the Drosophila toe gene (asterisk). Differential splicing in the 5' half of the Tribolium eyg transcript generates two predicted protein isoforms, one of which (Tc_eyg PA) contains a complete PD, whereas the other contains a truncated PD, which lacks the PAI subdomain (Tc_eyg PB). Protein domain regions are drawn to approximate relative scale and color coded: Red = PAI subdomain, grey = linker region, orange = RED subdomain, green = HD.
