We welcome enquiries from PhD-qualified researchers from all countries outside the UK wishing to apply for a European Commission-funded Marie Sklodowska-Curie Individual Fellowship to come to work with us at Aston. Subject areas might include recombinant protein production in yeast, translational processes in recombinant protein production, bioprocessing and the regulation of aquaporin water channels. Please contact Roslyn Bill for further details.
Membrane proteins play pivotal roles in all cellular functions. These include the transport of nutrients, the export of toxins and cell-cell interactions. They are also ubiquitous: ~30% of all proteins in all cells are membrane proteins. Consequently they are already key drug targets, with the majority of prescription pharmaceuticals on the market being targeted to this class of protein. Unfortunately, however, they are neither naturally abundant nor stable, which means that in the vast majority of cases extracting them from natural sources is not a viable option in order to study their structures, functions and biochemistry.
A main theme of our research activity is developing yeast as a “cell factory” to make membrane proteins in sufficient quantity and of appropriate quality for further study. Our approach is to move away from “trial and error” and to rationalize recombinant protein production by understanding the host cell response to it. We aim to:
- increase the volumetric yield – Microb Cell Fact. 2010, 9:47;
- increase the yield “per cell” – BMC Genomics. 2008, 9:365; Microb Cell Fact. 2009, 8:1; Microb Cell Fact. 2009, 8:35; and
- understand the molecular mechanisms involved – Nat Biotechnol. 2011, 29: 335-340.
Our review in Biochem Soc Trans provides a good overview of our approach – see Biochem Soc Trans. 2011, 39: 719-723.

A second theme of our work is examining in detail the regulation of water channel proteins (aquaporins), which is one of the protein families we produce in our yeast cell factories and are of interest as novel drug targets. We recently showed that AQP1 is regulated by extracellular water availability (Biochemistry. 2010, 49:821-3). This work was featured on the front cover of its issue, and as part of the 50th birthday cover. To listen to a podcast on our work on membrane proteins more generally click here.
