Our research focus is to combine biochemical and biophysical techniques to investigate the structure and function of two classes of membrane proteins. In the first instance, we are investigating the mechanism of a zinc transporter, hZIP4. This protein has been implicated in the initiation and progression of pancreatic cancer. Despite the central role of this protein in cellular homeostasis, the mechanism of cation transport is not well understood. Secondly, we have been investigating the molecular determinants that help to define the functionality of opsin proteins.
