Plasmodium vivax malaria is a globally widespread disease responsible for 50% of human malaria cases in Central and South America, South East Asia and Indian subcontinent. The rising severity of the disease and emerging resistance of the parasite has emphasized the need for the search of novel therapeutic targets to combat P. vivax malaria. Plasmepsin 4 (PM4) a food vacuole aspartic protease is essential in parasite functions and viability such as initiating hemoglobin digestion and processing of proteins and is being looked upon as potential drug target. Although the plasmepsins of Plasmodium falciparum have been extensively studied, the plasmepsins of P. vivax are not well characterized. This is the first report detailing complete PM4 gene analysis from Indian P. vivax isolates. Blast results of sequences of P. vivax plasmepsin 4 (PvPM4) shows 100% homology among isolates of P. vivax collected from …
