Abstract
G-protein-coupled receptors (GPCRs) are of prime importance for cell signal transduction mechanisms and are the target of many current and potential drugs. However, structural data on these membrane proteins is still scarce because of their low natural abundance and the low efficiency of most of the expression systems currently available. This review presents the most important expression systems currently employed for heterologous expression of GPCRs; Escherichia coli, yeast, insect cells and mammalian cells. After briefly recalling the specificity, advantages and limitations of each system, particular emphasis is put on the quantitative comparison of these expression systems in terms of overall expression yield, and on the influence of various factors (primary sequence, origin, cell type, N- and C-terminal tags) on the results.Keywords
