One of the key steps of structural genomics and proteomics is high-throughput expression of many target proteins. Gene cloning, especially by ligation-independent cloning techniques, and recombinant protein expression using microbial hosts such as Escherichia coli and the yeast Pichia pastoris are w

β¦ Synopsis
The production of sufficient quantities of protein is an essential prelude to a structure determination, but for many viral and human proteins this cannot be achieved using prokaryotic expression systems. Groups in the Structural Proteomics In Europe (SPINE) consortium have developed and implemented high-throughput (HTP) methodologies for cloning, expression screening and protein production in eukaryotic systems. Studies focused on three systems: yeast (Pichia pastoris and Saccharomyces cerevisiae), baculovirus-infected insect cells and transient expression in mammalian cells. Suitable vectors for HTP cloning are described and results from their use in expression screening and protein-production pipelines are reported. Strategies for co-expression, selenomethionine labelling (in all three eukaryotic systems) and control of glycosylation (for secreted proteins in mammalian cells) are assessed.

Of the wide variety of regulatory systems that have been developed to control gene expression in higher eukaryotes, those utilizing elements from prokaryotic systems presently achieve the highest specificity. In particular, systems based on the repressor/operator elements of an Escherichia coil tetr
## Abstract The method of crosslinking combined with mass spectrometry is being gradually accepted as a technology enabling detailed structural information on proteins and protein complexes. Intrinsic challenges of the method, which have prevented its widespread use, are being progressively address
