Evolutionary Pressures on Apicoplast Transit Peptides (2004)

Ralph, Stuart A., Foth, Bernardo J., Hall, Neil, McFadden, Geoffrey I.

Malaria parasites (species of the genus Plasmodium) harbour a relict chloroplast (the apicoplast) that is the target of novel anti-malarials. Numerous nuclear-encoded proteins are translocated into...

Trafficking and assembly of the cytoadherence complex in Plasmodium falciparum-infected human erythrocytes

Wickham, Mark E., Rug, Melanie, Ralph, Stuart A., Klonis, Nectarios, McFadden, Geoffrey I., Tilley, Leann, ...

After invading human erythrocytes, the malarial parasite Plasmodium falciparum, initiates a remarkable process of secreting proteins into the surrounding erythrocyte cytoplasm and plasma membrane....

A Type II Pathway for Fatty Acid Biosynthesis Presents Drug Targets in Plasmodium falciparum

Waller, Ross F., Ralph, Stuart A., Reed, Michael B., Su, Vanessa, Douglas, James D., Minnikin, David E., ...

It has long been held that the malaria parasite, Plasmodium sp., is incapable of de novo fatty acid synthesis. This view has recently been overturned with the emergence of data for the presence of a...

Phenotypic variation of Plasmodium falciparum merozoite proteins directs receptor targeting for invasion of human erythrocytes

Duraisingh, Manoj T., Triglia, Tony, Ralph, Stuart A., Rayner, Julian C., Barnwell, John W., McFadden, Geoffrey I., ...

The members of the phylum Apicomplexa parasitize a wide range of eukaryotic host cells. Plasmodium falciparum, responsible for the most virulent form of malaria, invades human erythrocytes using...

Antigenic variation in Plasmodium falciparum is associated with movement of var loci between subnuclear locations

Ralph, Stuart A., Scheidig-Benatar, Christine, Scherf, Artur

Much of the success of Plasmodium falciparum in establishing persistent infections is attributed to immune evasion through antigenic variation. This process involves periodically exchanging variants...

Transcriptome analysis of antigenic variation in Plasmodium falciparum - var silencing is not dependent on antisense RNA

Ralph, Stuart A, Bischoff, Emmanuel, Mattei, Denise, Sismeiro, Odile, Dillies, Marie-Agnès, Guigon, Ghislaine, ...

A microarray analysis of Plasmodium falciparum selected to express different var genes suggests that antisense transcripts are not responsible for the transcriptional silencing of non-expressed var...

Membrane transporters in the relict plastid of malaria parasites

Mullin, Kylie A., Lim, Liting, Ralph, Stuart A., Spurck, Timothy P., Handman, Emanuela, McFadden, Geoffrey I.

Malaria parasites contain a nonphotosynthetic plastid homologous to chloroplasts of plants. The parasite plastid synthesizes fatty acids, heme, iron sulfur clusters and isoprenoid precursors and is...

Evolution of malaria parasite plastid targeting sequences

Tonkin, Christopher J., Foth, Bernardo J., Ralph, Stuart A., Struck, Nicole, Cowman, Alan F., McFadden, Geoffrey I.

The transfer of genes from an endosymbiont to its host typically requires acquisition of targeting signals by the gene product to ensure its return to the endosymbiont for function. Many hundreds of...
