Summary
Several years ago we identified the cell membrane protein PETA-3-CD151 based on its ability to cause activation of blood platelets, suggesting a role in thrombosis. More recently we found that the protein is present in a variety of tissues, although its distribution in those tissues is often restricted. It is abundant in a variety of cancer cells, and is present on tissue mast cells that mediate allergic reactions. PETA-3-CD151 forms complexes with molecules (integrins) that are associated with ....Several years ago we identified the cell membrane protein PETA-3-CD151 based on its ability to cause activation of blood platelets, suggesting a role in thrombosis. More recently we found that the protein is present in a variety of tissues, although its distribution in those tissues is often restricted. It is abundant in a variety of cancer cells, and is present on tissue mast cells that mediate allergic reactions. PETA-3-CD151 forms complexes with molecules (integrins) that are associated with cell adhesion and migration, and antibodies to this protein inhibit cell movement. Thus PETA-3-CD151 appears to be involved in cellular interactions that are critical for normal tissue development and function, and may be involved in several disease processes including cancer invasion and metastasis. The molecular basis of PETA-3-CD151 function is not understood and is the focus of this application.Read moreRead less

Summary
Up to 10% of the world's population will suffer from malaria in any given year and for over a million this disease will be fatal. This devastating disease is caused by the parasite Plasmodium falciparum that infects and destroys our red blood cells. Infected red cells are greatly modified by the parasites so they can feed and avoid elimination by the human immune system. We wish to investigate the red blood cell modification process and assess it as a potential target for anti-malarial drugs.
