Research Abstract

RNA helicase are enzymes to modulate the structures of double strand RNA and RNA-protein and are classified into families by their functional domains. There are several hundred kinds of putative RNA helicases, however, functions of only a little kind of helicases are elucidated. Thus, in this study I try to clarify the biological functions and reaction mechanisms of the novel RNA helicases by combination of Drosophila genetics and proteomic analysis.
