Malaria Pharmacology Comments
The P. falciparum genome encodes 10 aspartic proteases, classed together as the plasmepsin family, which are involved in diverse cellular processes [3]. The P. falciparum plasmepsin V (PfPMV) enzyme processes proteins for export into the host erythrocyte and has been shown to be essential for parasite asexual blood stage development [1-2]. PfPMV has also been shown to be essential for gametocyte development, validating it as a potential target for the development of transmission-blocking drugs [5].
