Protein Structure Initiative (PSI):
The Protein Structure Initiative (PSI) is a federal, university, and industry effort aimed at dramatically reducing the costs and lessening the time it takes to determine a three-dimensional protein structure. The long-range goal of the PSI is to make the three-dimensional atomic-level structures of most proteins easily obtainable from knowledge of their corresponding DNA sequences.
Expected benefits from the PSI include: structural descriptions to help researchers discover the functions of proteins, design experiments, and solve other key biomedical problems; faster identification of promising new structure-based medicines; better therapeutics for treating both genetic and infectious diseases; and development of technology and methodology for protein production and crystallography.

The Joint Center for Structural Genomics
This California-based center is developing high-throughput methods for protein production, crystallization, and structure determination. It will initially focus on novel structures from the roundworm Caenorhabditis elegans and on human proteins thought to be involved in cell signaling. It will also determine the structures of similar proteins from other organisms to ensure the inclusion of the greatest number of different protein folds.
Program Description
Organizations: The Scripps Research Institute, University of California at San Diego, Stanford University, Stanford Synchrotron Radiation Labs, Genomics Institute of the Novartis Research Foundation
Principal investigator: Ian Wilson, The Scripps Research Institute
Targets: Thermotoga maritima, mouse
Technology: crystallome screen of T. Maritima proteome; beamline automation; data centric informatics platform; nanovolume crystallization

The Midwest Center for Structural Genomics
This consortium of seven institutions is working to reduce the average cost of a protein structure from $100,000 to $20,000. The group will select protein targets from all three kingdoms of life (Eukarya, Archaea, and Bacteria), with an emphasis on previously unknown folds and on proteins from disease-causing organisms.
Program Description
Organizations: Argonne National Laboratory, Northwestern University, Washington University School of Medicine, University College London, University of Texas Southwestern Medical Center, University of Toronto, University of Virginia
Principal investigator: Andrzej Joachimiak, Argonne National Laboratory
Targets: microorganisms, especially pathogens
Technology: HTP target selection; automated gene cloning, protein expression, and solubility evaluation; low cost and high density fermentation; automated purification, crystallization, and structure determination; computational methods for fold analysis and function prediction; databases and LIMS
