Summary: Transmission from host to host is fundamental to any parasite's lifecycle. For many, this means a free-living phase in the outside world, during which they protect themselves from harsh environmental conditions; nematode larvae, for example, are protected by their cuticle and coccidians produce oocyst walls. These barriers are created when large proteins are processed into smaller tyrosine-rich fragments which then crosslink to form a protective structure. We will discover the processing pathways involved in the formation of oocyst walls of coccidia. This knowledge will lead to a better understanding of structural protein biosynthesis in parasites and the discovery of new control targets.
