Egress of Plasmodium from host erythrocytes is mediated by effector proteins. Aspartic protease plasmepsin X (PM X) regulates the activity for many of these effectors, is essential for replication and is a promising drug target. Here, Mukherjee et al. map the self-cleavage sites of PM X, show that the N-terminal part of its prodomain is required for intracellular trafficking and correlate the maturation and subcellular activity of PM X in microneme, exoneme and rhoptry organelle function.
