Approximately, 29,000 protein structures are deposited in the Protein Databank (January 2005), but only about 90 of which are independent membrane protein structures. This represents a significant increase in knowledge compared with a matter of only 5 years ago when a mere handful of membrane protein structures were available. Despite the advances, our understanding of the structure–function relationships and mechanism of action of many membrane proteins is still lacking. This is particularly true of many of the more clinically relevant membrane proteins, such as the G-protein-coupled receptors (GPCRs). The GPCRs regulate cellular responses to a wide range of biologically active molecules including hormones and drugs and are thus important targets for therapeutic intervention in a number of disease states. However, the increasing number of membrane protein structures has provided a critical mass of information which has yielded a more rational approach to the process of obtaining diffraction quality crystals. It is the different stages of this process; expression, solubilisation, purification, and crystallisation that will be covered in this lecture.
