Function

PLM5_PLAVS During the asexual blood stage, plays an essential role in the export of several proteins into the host erythrocytes by cleaving the pentameric localization motif RxLxE/Q/D (termed Plasmodium export element (PEXEL)) located downstream of the N-terminal secretory signal sequence (PubMed:24983235). Specifically, cleaves after the leucine residue in the RxLxE/Q/D (or RxLxxE) motif of exported proteins including EMP1 (By similarity). Also, by regulating protein export, plays an essential role in gametocyte development and thus parasite transmission to the mosquito vector (By similarity).[UniProtKB:Q8I6Z5][UniProtKB:W7JPD9]^[1]

Publication Abstract from PubMed

Plasmepsin V, an essential aspartyl protease of malaria parasites, has a key role in the export of effector proteins to parasite-infected erythrocytes. Consequently, it is an important drug target for the two most virulent malaria parasites of humans, Plasmodium falciparum and Plasmodium vivax. We developed a potent inhibitor of plasmepsin V, called WEHI-842, which directly mimics the Plasmodium export element (PEXEL). WEHI-842 inhibits recombinant plasmepsin V with a half-maximal inhibitory concentration of 0.2 nM, efficiently blocks protein export and inhibits parasite growth. We obtained the structure of P. vivax plasmepsin V in complex with WEHI-842 to 2.4-A resolution, which provides an explanation for the strict requirements for substrate and inhibitor binding. The structure characterizes both a plant-like fold and a malaria-specific helix-turn-helix motif that are likely to be important in cleavage of effector substrates for export.
