Duplicated Myosin V Genes in Teleosts Show Evolutionary Rate Variations among the Motor and Cargo-Binding Domains

We analyzed evolutionary rates of conserved, duplicated myosin V (myo5) genes in nine teleost species to examine the outcomes of duplication events. Syntenic analysis and ancestral chromosome mapping suggest one tandem gene duplication event leading to the appearance of myo5a and myo5c, two rounds of whole genome duplication for vertebrates, and an additional round of whole genome duplication for teleosts account for the presence and location of...
