| STRING - Known and Predicted Protein-Protein Interactions
| |
| |
|
| | STRING is a database of known and predicted protein interactions. The interactions include direct (physical) and indirect (functional) associations; they are derived from four sources: |
Genomic Context | |
High-throughput Experiments | |
(Conserved) Coexpression | |
Previous Knowledge | |

| STRING quantitatively integrates interaction data from these sources for a large number of organisms, and transfers information between these organisms where applicable. The database currently covers 5'214'234 proteins from 1133 organisms. |
