Distribution of kinesin protein architectures in 45 diverse eukaryotes. Pfam and CDD searches were used to identify putative gene architectures for the 1624 kinesin proteins identified in the genome datasets. All unique gene architectures identified in two or more genomes are shown here while all 105 different gene architectures identified are shown in Additional file 4. Presence of a gene architecture in a genome is indicated by a filled circle, absence/not-found is indicated by an open circle. Species analyzed are grouped into higher taxonomic units. Architectures used in Dollo parsimony analyses are marked 'c' (character), while architectures, which appeared not to be homologous based on further investigation (see Additional file 6), are marked 'd(ex)' (discounted and excluded), while this analysis adjusted the taxon distribution of some architecture characters marked 'd/c' (discounted and corrected) adjacent to the first column. Domains found more than once are numbered to indicate the multiples in which the domains are found (e.g. x2-7 indicates the protein contained between 2 and 7 copies of the domain).
