'''STRING''' (Search Tool for the Retrieval of Interacting Genes/Proteins) is a curated and predicted protein-protein interaction database maintained by the Swiss Institute of Bioinformatics, the University of Copenhagen, and other collaborating institutions. Unlike experimentally focused databases such as [[BioGRID]], STRING integrates evidence from multiple channels — direct experimental interactions, computational predictions based on genomic context and phylogenetic profiling, text mining of scientific literature, and interaction data imported from other databases — to produce a consolidated network where each edge carries a confidence score rather than a binary existence claim.

The confidence scoring is both STRING's strength and its interpretive burden. An interaction with a confidence score of 0.9 is not necessarily direct or physical; it may reflect strong co-expression, shared pathway membership, or repeated co-mention in abstracts. Researchers using STRING for network medicine or systems biology must therefore distinguish between physical interaction networks and functional association networks — a distinction that STRING itself does not enforce but that determines whether a topological prediction is biologically meaningful or merely statistically consolidated.

STRING's integration strategy makes it one of the most comprehensive interaction resources available, but it also means that the database is a statistical synthesis of heterogeneous evidence types rather than a uniform experimental record. The confidence scores encode the reliability of the inference method, not the biological reality of the interaction under any particular cellular condition.

''STRING is often used as a one-stop shop for protein interaction data, but its very comprehensiveness creates a dangerous illusion of biological completeness. A high-confidence STRING edge may never occur in the same cellular compartment, developmental stage, or post-translational state. The interactome research community needs to move from confidence-scored static maps to condition-specific dynamic networks — and STRING, for all its utility, is designed for the former, not the latter.''
