about PSI

With the completion of the sequencing of the genomes of human and other organisms, attention has focused on the characterization and function of proteins, the products of genes. The availability of sequence data and the growing impact of structural biology on biomedical research have prompted scientific groups from several countries to undertake projects in the emerging field of structural genomics. The objective is to make these structures widely available for clinical and basic studies that will expand the knowledge of the role of proteins both in normal biological processes and in disease. The National Institute of General Medical Sciences (NIGMS) played a major role in the early planning for structural genomics and in 1999 organized a national program, the Protein Structure Initiative.

PSI Mission

The long-range goal of the Protein Structure Initiative (PSI) is to make the three-dimensional atomic-level structures of most proteins easily obtainable from knowledge of their corresponding DNA sequences. Specific goals include:

  • Developing methodology and technology to increase success rates and lower costs of structure determination,
  • Constructing and automating the protein production and structure determination pipeline, and
  • Determining unique protein structures (less than 30% identical in sequence to proteins for which structures had already been determined).
