STRING (Search Tool for Retrieval of Interacting Genes/Proteins) 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.
This resource is a provider. This means that
while it may have its own prefix, it actually reuses the identifiers provided by the
uniprot
prefix. For all use cases, you should use uniprot
instead of string
.
string
Local identifiers in Search Tool for Retrieval of Interacting Genes/Proteins should match this
regular expression:
^([A-N,R-Z][0-9][A-Z][A-Z, 0-9][A-Z, 0-9][0-9])|([O,P,Q][0-9][A-Z, 0-9][A-Z, 0-9][A-Z, 0-9][0-9])|([0-9][A-Za-z0-9]{3})$
Compact URIs (CURIEs) constructed from Search Tool for Retrieval of Interacting Genes/Proteins should match
this regular expression:
^string:([A-N,R-Z][0-9][A-Z][A-Z, 0-9][A-Z, 0-9][0-9])|([O,P,Q][0-9][A-Z, 0-9][A-Z, 0-9][A-Z, 0-9][0-9])|([0-9][A-Za-z0-9]{3})$
The metaregistry provides mappings between the Bioregistry and other registries. There are
8 mappings to external registries for string
with
5 unique external prefixes.

Providers are various services that resolve CURIEs to URLs. The example CURIE
string:P53350
is used to demonstrate the provides available for
string
. Generation of OLS and BioPortal URLs requires additional programmatic
logic beyond string formatting.
Additional providers curated in the Bioregistry are listed here.
