Partial cDNA sequence analysis of myosin Va from rainbow trout (Oncorhynchus mykiss) and its relationship to myosin v isoforms from other vertebrates.

Partial cDNA sequences of myosin V from rainbow trout Oncorhynchus mykiss were analyzed and showed high similarity to MVa from other vertebrates. Phylogenetic analysis has shown that events resulting in the formation of paralogous copies of myosin Va, Vb, and Vc occurred before the divergence of vertebrates into different classes. Expression analysis of myosin Va, Vb, and Vc in different O. mykiss tissues revealed MVa exclusively expressed in hypophysis and brain whereas Vb and Vc were expressed in practically all tissues analyzed. The nucleotide sequence for myosin V was explored in a fish species for the first time and these results represent an important start in understanding the organization, evolution, and expression of myosins in early vertebrates. The data presented here represent contributions to the knowledge of rainbow trout genome. A better understanding of this economically important species could assist in development of improved strains of this fish for aquaculture.

Localization of myosin-Va in subpopulations of cells in rat endocrine organs

Myosin-Va is a Ca 2+/calmodulin-regulated unconventional myosin involved in the transport of vesicles, membranous organelles, and macromolecular complexes composed of proteins and mRNA. The cellular localization of myosin-Va has been described in great detail in several vertebrate cell types, including neurons, melanocytes, lymphocytes, auditory tissues, and a number of cultured cells. Here, we provide an immunohistochemical view of the tissue distribution of myosin-Va in the major endocrine organs. Myosin-Va is highly expressed in the pineal and pituitary glands and in specific cell populations of other endocrine glands, especially the parafollicular cells of the thyroid, the principal cells of the parathyroid, the islets of Langerhans of the pancreas, the chromaffin cells of the adrenal medulla, and a subpopulation of interstitial testicular cells. Weak to moderate staining has been detected in steroidogenic cells of the adrenal cortex, ovary, and Leydig cells. Myosin-Va has also been localized to non-endocrine cells, such as the germ cells of the seminiferous epithelium and maturing oocytes and in the intercalated ducts of the exocrine pancreas. These data provide the first systematic description of myosin-Va localization in the major endocrine organs of rat. © 2008 Springer-Verlag.
