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:Biology Mission

The goal of the Protein Structure Initiative:Biology program is to apply the paradigm of high-throughput structure determination via highly organized networks of investigators to solve the three-dimensional structure of proteins and macromolecular complexes of substantial biological and biomedical problems and to use these structures to understand their biological function.

The Protein Structure Initiative Structural Biology Knowledgebase (SBKB) is a Resource Center within the PSI Program. The goal of the Structural Biology Knowledgebase is to turn the products of the Protein Structure Initiative effort into knowledge that is important for understanding living systems and disease.
