Plasmodium parasites are the causative agent of malaria. The parasite requires the invasion of host red blood cells to propagate itself and cause disease and uses parasite-specific secretory organelles to do so. I will characterize these invasion organelles, the micronemes and rhoptries, by proximity-dependent labeling using known resident proteins AMA1, RAP1, and RON4. I will identify known and novel proteins that are trafficked to and localize in these invasion organelles.
