Schematic diagram of the domain structures of the orphan myosins of the Fungi/Metazoa lineage. The sequence names of the ophan myosins are given in the motor domain of the respective myosins. Color keys to the domain names and symbols are given on the right except for the myosin domain, which is colored in blue. Myosin names next to domain representations list orthologs from closely related species or orthologs from the same species. These sequences have a similar domain organization. Sequences that are not orthologs and have not resulted from recent gene duplications are shown separately, although their domain organizations might be very similar. The myosin domains without names on the bottom symbolize that only head fragments are available for the sequences listed on the right. The exclamation mark on the left side of some sequences signifies that the corresponding sequences (especially the tail regions) have not completely been validated because of missing comparative genome sequences. Those sequences and corresponding tail domain predictions might change with upcoming genome sequences of related species. Abbreviations for the domains are: SAM, sterile alpha motif; Vicilin-N, Vicilin amino-terminal region; WW, tryptophan-tryptophan motif domain; Y phosphatase, protein tyrosine phosphatase, catalytic domain.
