Research Abstract |
By in vitro actin polymerization assay, we identified N'-(4-(diethylamino) benzylidene)-4-methoxybenzohydrazide (DBHA) as a dynamin inhibitor. Effects of DBHA on ruffle formation and cell migration were also examined, and the results on DBHA were published in a journal article. Dynamin isoforms present in plasmodium falciparum, pfDyn1 and pfDyn2, were expressed in insect cells, and they were purified. Using these recombinant proteins, we demonstrated that both pfDyn1 and pfDyn2 have GTPase activity. It was also shown that pfDyn1 and pfDyn2 have an ability to deform lipid membranes. Furthermore, pfDyn2 inhibitor candidate molecules were determined by GTPase activity assay-based drug screening.
