Summary
When the bacteria that cause meningococcal disease invade cells, they use specialized cell surface pore proteins to hijack the human cell and maintain infection. This research will study the structure of these bacterial pore proteins to help understand how they function to subvert normal cellular processes, and this insight will be important in the development of new treatments for meningococcal disease.

Summary
The cytokines play important roles in the immune system during blood cell development and inflammation, and in nerve growth, bone remodeling, reproduction and heart development. Cell responses are initiated by a cytokine bringing together on the cell surface a receptor complex made up of multiple molecules. This project will investigate the atomic structure of the cell surface macromolecular complex, and hence the underlying mechanism by which cytokine signals are initiated.

Summary
We aim to understand how insulin binds to and activates its cell-surface receptor. This information has implications for the design of anti-diabetic agents targetted directly to the insulin receptor. Diabetes is a global health problem and is classified by the World Health Organization as an epidemic. The results also have implications for the insulin-like growth factor receptor system and the design of anti-cancer therapeutics directed towards it .
Structural Basis Of Ligand Binding To Type 1 Insulin-like Growth Factor Receptor (IGF-1R)

Summary
Insulin-like growth factors are involved in normal growth and development. However, they are also implicated in cancer development and progression. We are seeking to understand the way in which these growth factors bind to their receptor on the surface of the cell and stimulate the cell to survive, proliferate and migrate to new tumour sites. Such knowledge will be useful in the design of molecules that could potentially intervere with this process and thus be used as anti-cancer therapeutics.

Summary
Cells require numerous signalling pathways to keep various cellular processes coordinated and under control. One of the most important aspects of signalling is formation of complexes involving two or more different proteins. One of the recently identified players in the formation of these signalling complexes is the so-called forkhead-associated (FHA) module, FHA modules are protein sequences of ~130 amino acids that appear as a part of signalling proteins and bind to specific sequences on signa ....Cells require numerous signalling pathways to keep various cellular processes coordinated and under control. One of the most important aspects of signalling is formation of complexes involving two or more different proteins. One of the recently identified players in the formation of these signalling complexes is the so-called forkhead-associated (FHA) module, FHA modules are protein sequences of ~130 amino acids that appear as a part of signalling proteins and bind to specific sequences on signalling protein partners. Many proteins containing FHA modules are important for the repair of damaged DNA and the stability of chromosomes. The aim of our studies is to understand the molecular and atomic details of how FHA modules bind their partners. This is the first step towards designing therapeutic agents against various forms of cancer where DNA is damaged.Read moreRead less
