Whether you’re interested in a single protein or many, you now have the chance to join the Protein Structure Initiative’s PSI:Biology network, which will apply high-throughput structural approaches to solve interesting biological problems.

We have just released three funding opportunities that will establish the core of the PSI:Biology research network:

Centers for High-Throughput Structure Determination – large-scale centers that will have the capacity to solve structures on the order of several hundred per year.

Centers for Membrane Protein Structure Determination – small centers that will devote special effort to solving the structures of these proteins.

Consortia for High-Throughput Enabled Structural Biology Partnerships – these awards will support functional studies of proteins proposed by individuals or groups of researchers from across all fields of biology as well as support the structural determination of those proteins through consortia with the PSI:Biology structure centers. Ideal projects will integrate functional and structural data for a large number of protein structures to solve significant biological problems.

In addition to these opportunities, we plan to issue program announcements for experimental technology development, computational and molecular modeling and more ways for partners to bring their interests to the target-setting table. We’ll announce these in the NIH Guide and here in the Feedback Loop.

If you have just one or two proteins that need to be solved, you can nominate them as targets for structure determination via the PSI Structural Genomics Knowledgebase, which offers a cool widget so you can easily access the site from your Web page.

UPDATE: The due dates for letters of intent and applications have been extended to September 28, 2009, and October 28, 2009, respectively. For more details, see NOT-GM-09-026.
