title: Breaking the barriers in membrane protein crystallography.
abstract: As we appreciate the importance of stabilising membrane proteins, the barriers towards their structure determination are being broken down. This change in mindset comes hand-in-hand with more effort placed on developing methods focused at screening for membrane proteins which are naturally stable in detergent solution or improving those that are not so. In practice, however, it is not easy to decide the best strategy to monitor and improve detergent stability, requiring a decision-making process that can be even more difficult for those new to the field. In this review we outline the importance of membrane protein stability with discussions of the stabilisation strategies applied in context with the use of crystallisation scaffolds and the different types of crystallisation methods themselves. Where possible we also highlight areas that we think could push this field forward with emerging technologies, such as X-ray free electron lasers (X-feL), which could have a big impact on the membrane protein structural biology community. We hope this review will serve as a useful guide for those striving to solve structures of both pro- and eukaryotic membrane proteins.
