| Research Abstract |
Myosin heavh chain (MYH) is essential protein for a wide range of motile processes in eukaryotic cells and fast skeletal MYH genes (MYHs) formed clusters in mammals and teleosts. In the present study, we found that the fast skeletal MYHs formed a cluster also in the lamprey, agnathan vertebrate. Moreover, in vivo promoter assay demonstrated that lamprey fast skeletal MYH promoters could drive reporter gene to express in the fast skeletal muscle in zebrafish embryo. These results suggest that in the early vertebrates, fast skeletal MYHs had already formed clusters and the basic mechanism for transcriptional control of skeletal muscle development had been determined.
