What it does ...
STRING is a database of predicted functional associations among genes/proteins.
 
Genes of similar function tend to be maintained in close neighborhood (), tend to be present or absent together, i.e. to have the same phylogenetic occurrence (), and can sometimes be found fused into a single gene encoding a combined polypeptide ().
 
STRING integrates this information from as many genomes as possible to predict functional links between proteins. The database currently contains 356775 genes in 110 species.
