Research Interest

The formation of stable, fibrillar protein assemblies is associated with many disease states, including Alzheimer's disease and Type II diabetes. These are non-functional deposits. Protein aggregates that have similar structural features but which are functional have been identified in several microorganisms. In these cases the self-assembly of the protein is advantageous to the organism. For example, hydrophobins are fungal proteins that self-assemble in an ordered manner into amphipathic films at air:water interfaces. They reduce the surface tension at air:water boundaries and form very hydrophobic coatings on fungal spore surfaces which facilitate dispersal in air. Hydrophobin assemblies share the ordered beta-sheet structural core that has been characterized in amyloid deposits.
