The Malarial Serine Protease SUB1 Plays an Essential Role in Parasite Liver Stage Development
Transmission of the malaria parasite to its vertebrate host involves an obligatory exoerythrocytic stage in which extensive asexual replication of the parasite takes place in infected hepatocytes. The resulting liver schizont undergoes segmentation to produce thousands of daughter merozoites. These are released to initiate the blood stage life cycle, which causes all the pathology associated wi...
متن کاملPlasmodium subtilisin-like protease 1 (SUB1): Insights into the active-site structure, specificity and function of a pan-malaria drug target
Release of the malaria merozoite from its host erythrocyte (egress) and invasion of a fresh cell are crucial steps in the life cycle of the malaria pathogen. Subtilisin-like protease 1 (SUB1) is a parasite serine protease implicated in both processes. In the most dangerous human malarial species, Plasmodium falciparum, SUB1 has previously been shown to have several parasite-derived substrates, ...
متن کاملIdentification of a nucleoside/nucleobase transporter from Plasmodium falciparum, a novel target for anti-malarial chemotherapy.
Plasmodium, the aetiologic agent of malaria, cannot synthesize purines de novo, and hence depends upon salvage from the host. Here we describe the molecular cloning and functional expression in Xenopus oocytes of the first purine transporter to be identified in this parasite. This 422-residue protein, which we designate PfENT1, is predicted to contain 11 membrane-spanning segments and is a dist...
متن کاملPlasmodium Falciparum Strain Identification
The polymerase chain reaction (PCR) was employed for detection and strain identification of P. falciparum in a comparative field study of Indian isolates. The primers were selected from highly conserved regions flanking the variable, tandemly repeated regions of highly polymorphic cell surface antigens, major merozoite surface antigen-1 (MSP-1), major surface antigen-2 (MSP-2), circumsporozoite...
متن کاملSurvival strategies of the malarial parasite Plasmodium falciparum
Plasmodium falciparum, the protozoan parasite causing falciparum malaria, is undoubtedly highly versatile when it comes to survival and defence strategies. Strategies adopted by the asexual blood stages of Plasmodium range from unique pathways of nutrient uptake to immune evasion strategies and multiple drug resistance. Studying the survival strategies of Plasmodium could help us envisage strat...
