Abstract

Malaria proteases are attractive anti-malarial targets because of their roles in parasite development and infection. Falcipain-2 (FP-2), a food vacuole cysteine protease in Plasmodium falciparum, is involved in hemoglobin degradation and cleavage of cytoskeletal elements. To understand the route of trafficking and identify the signals involved in trafficking to food vacuole, we have generated transgenic parasites expressing green fluorescent protein (GFP) fusion proteins comprising of N-terminal regions of falcipain-2 fused to GFP. Using falcipain2-GFP chimeras and anti-falcipain-2 antibody, we show that falcipain-2 is trafficked through a classical vesicle mediated secretory pathway involvi..
