Howitt Group - Transporter structure and function
We are interested in how transporters function and we aim to understand their molecular mechanisms. We are using heterologous expression systems to characterize transporters and mutant variants that have been generated by site-directed mutagenesis or random methods. This allows us to test hypotheses about which regions of the transporter are important for function.
We are also interested in science education, especially in student perceptions of research and how this impacts on their learning of science.
