Nuclear architecture is critical to the preservation of genome integrity. The aim of this research proposal is to delineate the role of chromatin organisation in transcription factor target search and damage site recruitment of DNA repair factor machinery. To achieve this I have developed fluorescence microscopy methods to monitor changes in chromatin structure with submicron resolution. Only with this technology can I determine how chromatin dynamics maintain genome integrity or induce disease.
The Molecular Mechanism Of Ion-coupled Transport In The Brain

Summary
Cells in the brain communicate through chemical signals called neurotransmitters. Neurotransmitter transporters reside in the membranes of cells and are responsible for regulating levels of these chemicals in the brain. They play an important role in the normal function of the human brain but their dysfunction is responsible for many diseases including Alzheimer's disease and motor neuron disease. It is crucial to understand how these proteins work in both normal and disease states.
A Targeted Nutrient-depletion Approach To Tackle Prostate Cancer

Summary
Prostate cancer is the most prevalent male specific cancer, and has a similar incidence to breast cancer in women. We are studying the role of protein pumps that control the amount of nutrients taken into and out of cancer cells. We are aiming to structurally determine LAT1 and LAT3, two nutrient pumps important for cancer progression, and to use these structures as a platform for drug design where the intention is to drugs 'starve’ the cancer by restricting nutrient uptake.
Dissecting The Interactions Of Antimalarial Drugs With The Two Key Determinants Of Drug Resistance In The Malaria Parasite - The 'chloroquine Resistance Transporter' And The 'multidrug Resistance Transporter 1'

Summary
The malaria parasite is a single-celled organism which invades the red blood cells of its host. The aim of this fellowship is to study two proteins that are central to the parasite’s ability to evade the toxic effects of a number of drugs. The parasite's susceptibility to chloroquine, and other drugs, is altered by small changes in these proteins. This work will advance our understanding of the increasingly widespread phenomenon of antimalarial drug resistance, and of how it may be overcome.
