Protein structure, function and interactions

We use a variety of spectroscopic, biophysical and protein chemical techniques to study molecular chaperone proteins and their mechanism of stabilising other proteins, for example those involved in diseases of protein aggregation (Alzheimer’s, Parkinson’s, cataract etc.). NMR spectroscopy is the principal technique used to characterise these interactions.
