Facilitation of yeast-lethal membrane protein production by detoxifying with GFP tagging.

Recombinant techniques for target protein production have been rapidly established and widely utilised in today's biological research. Nevertheless, methods for membrane protein production have yet to be developed, since membrane proteins generally tend to be expressed at low levels, easily aggregated, and/or even toxic to their host cells. Here we report that a GFP-tagging technique can be applied for the stable production of membrane proteins that are toxic to their host cells when overexpressed, paving the way for future advances in membrane protein biochemistry and drug development.
