Metrics | tracking milestones made by PSI:Biology
Last updated:
The PSI:Biology Goals and Milestone Committee was charged with determining a
list of metrics that best convey the progress and impact of the PSI:Biology Network.

1. Quantitative Metrics
These tables provide a summary of the PSI:Biology targets being studied by the High-throughput and Membrane Protein Centers, as determined from depositions to TargetTrack or the PDB.
Table 27154. Numbers of targets in the PSI:Biology pipeline and the number of structures solved. (Metrics items 1.1-1.8)
Table 27155. Number of PSI:Biology targets classified by Target Category (Metrics items 1.9 - 1.10)
2. Structure Determination
This section counts the number of different structural and biological topics targeted by the PSI:Biology network as categorized in TargetTrack.
Table 27156. Types of protein targets among the PSI:Biology structures (Metrics item 2.1)
2.2 Structure Determination Methods 
Table 27157. Classifies PSI:Biology Structure by their structure determination method.
3. Network Building
One of the goals of the PSI:Biology program is to be a collaborative network for the greater biological community to rely on for structures and resources. This section counts the level of collaboration within the PSI:Biology Network and beyond it.
3.1 Collaboration

3.1.2 External to PSI
3.1.2.3 (Table 27158) Collaborations created by Community-nominated Target nominations
4. Experimental Data Resources
The PSI:Biology Network makes all of its research resources available to the public. The following resource counts come from center depositions and TargetTrack.
4.1 (Table 27159) Protocols used by the PSI:Biology program.
4.2 (Table 27160) Available PSI:Biology clones.
5. Technologies
The PSI:Biology Network also develops new technologies to overcome bottlenecks in the high-throughput protein production and structural determination pipeline. During PSI:Biology, technological developments are mainly underway for the membrane protein-focused centers and the high-throughput centers. This data is calculated from the PSI Technology Portal.
5.1 - 5.5 (Table 27161) Technologies from HTP and Membrane Protein Centers.
6. Publications
Below is a tabulation of the number, citation count, and impact of PSI:Biology publications, along with the number of times a center's PDB structure has been downloaded from all PDB sites. The download numbers exclude full PDB archive downloads. This data is collected from the PSI Publications Portal and the wwPDB site.
