abstract：:During blood-stage infection, malaria parasites export numerous proteins to the host erythrocyte. The Poly-Helical Interspersed Sub-Telomeric (PHIST) proteins are an exported family that share a common 'PRESAN' domain, and include numerous members in Plasmodium falciparum, Plasmodium vivax and Plasmodium knowlesi. In ...
