| Research Abstract |
We have clarified a novel regulatory mechanism of actin dynamics by dynamin/cortactin complex. The complex is ring-shaped and it changed the conformation upon dynamin GTP hydrolysis, from open ring to close ring. By the open-cloze motion, the complex bundled F-actins and stabilized the actin bundles. Furthermore, we identified N'-[4-(dipropylamino)benzylidene]-2-hydroxybenzohydrazide(DBHA)as a dynamin inhibitor that suppress dynamin-dependent actin regulation. DBHA inhibited recruitment of dynamin to the leading edge of migrating cancer cell line and ruffle formation. It also showed inhibitory effect in cell migration, invasion, and proliferation.
