During the 3 y course of the project, the different laboratories have developed their own protocols for protein production (Alzari et al., 2006; Aricescu et al., 2006) and QA of the produced proteins. Structural proteomics studies have significantly added to our knowledge of protein structures over the past few years and a large fraction of available protein structures in public databases result from high‐throughput structural proteomics studies.
