( a ). The genomic organisation of akirin orthologues across eukaryotic lineages. The schematic diagram is made to scale with exons as white boxes and introns as black lines. Positions of start and stop codons are identified in metazoan exons. Evidence is also presented suggesting that the coding sequence of the metazoan akirin proto-orthologue was derived from exons 2/3 of the choanoflagellate (M. brevicollis) gene (see main text). B. floridae akirin is composed of 5 exons and exon 5 is shaded with vertical lines to show that it is not equivalent to exon 5 of vertebrate akirins (see main text). (b). Shows the conservation of exon-exon boundaries across the metazoans. Different exons are shaded in different colours and are numbered with roman numerals. Exons are not to scale and represent an archetypal genomic organisation for the taxa shown. Double ended-arrows indicate conservation of exon-exon boundaries. A scenario depicting the evolution of the genomic organisation of akirin genes is shown (also, see main text).
