Malaria and Human ADFs (IMAGE) Walter and Eliza Hall Institute Caption A protein diagram shows the structure of the malaria parasite protein ADF1 (actin-depolymerising factor 1) (left) compared to a human ADF (right). The noticeable lack of the 'finger' in malaria parasite ADF1 led researchers from the Walter and Eliza Hall Institute in Melbourne, Australia, to upend the conventional theory of how the protein controlled cell movement.
