Schematic diagram of the domain structures of the orphan myosins from Stramenopiles. 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. Abbreviations for the domains are: CH, Calponin homology domain; GAF, domain present in phytochromes and cGMP-specific phosphodiesterases; HEAT repeat, named after the proteins huntingtin, elongation factor 3 (EF3), the 65 kDa alpha regulatory subunit of protein phosphatase 2A (PP2A) and the yeast PI3-kinase TOR1; Mis14, kinetochore protein Mis14 like.
