We have issued a request for information (RFI) seeking input on the most effective methods for the determination of membrane protein and large macromolecular assembly structures and/or the need for new tools to aid in structure determination of these proteins or protein complexes. To respond to the RFI, send an e-mail to NIGMSMembraneProteinRFI@mail.nih.gov by July 20.
The Protein Structure Initiative (PSI) began in 2000 with an initial goal to make the three-dimensional, atomic-level structures of most proteins easily obtainable from knowledge of their corresponding DNA sequences. During the current PSI:Biology phase, highly organized networks of investigators are applying the new paradigm of high-throughput structure determination, which was successfully developed during the earlier phases of the PSI, to study a broad range of important biological and biomedical problems.
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 PSI actively engages the scientific community in the selection of proteins for structure determination and is increasing its outreach, accessibility and impact on biomedical research via the PSI:Biology-Nature Structural Biology Knowledgebase , a continually updated portal to PSI data, resources and latest developments. Biological material resources generated by the PSI are shared with the scientific community through the PSI:Biology Materials Repository and through collaborations with PSI investigators.
