Biochemical characterization and chemical inhibition o PfATP4-associated Na+-ATPase activity in Plasmodium falciparum membranes

Rosling, James; Ridgway, Melanie; Summers, Robert; Kirk, Kiaran; Lehane, Adele


The antimalarial activity of chemically diverse compounds, including the clinical candidate cipargamin, has been linked to the ATPase PfATP4 in the malaria-causing parasite Plasmodium falciparum. The characterization of PfATP4 has been hampered by the inability thus far to achieve its functional expression in a heterologous system. Here, we optimized a membrane ATPase assay to probe the function of PfATP4 and its chemical sensitivity. We found that cipargamin inhibited the Na+-dependent ATPase...[Show more]
