Diversion at the ER: How Plasmodium falciparum exports proteins into host erythrocytes [version 2; peer review: 3 approved]

Malaria is caused by parasites which live in host erythrocytes and remodel these cells to provide optimally for the parasites' needs by exporting effector proteins into the host cells. Eight years ago the discovery of a host cell targeting sequence present in both soluble and transmembrane P. falciparum exported proteins generated a starting point for investigating the mechanism of parasite protein transport into infected erythrocytes. Since then many confusing facts about this targeting signal have emerged. In this paper, I try to make sense of them.
