What is string-db.org?

String-db.org is a free, open-source database that provides comprehensive information about protein-protein interactions for model organisms such as human, mouse, rat, fly, and worm. It integrates known and predicted interactions from multiple sources including experimental data, computational predictions, and literature text mining. The database contains over 200 million interactions between over 10 million proteins across all major model organisms. This makes it one of the largest and most comprehensive databases of protein-protein interactions available.

String-db.org offers a wide range of features that make it a valuable resource for researchers in the field of proteomics. These features include:

• Interactive web interface: The database can be easily searched and browsed using a variety of criteria, including protein name, gene name, or protein sequence. The interface also allows users to view detailed information about each interaction, including the source of the data, the experimental method used to detect the interaction, and the confidence score for the interaction.


• Bulk data download: Users can download the entire database or subsets of the data in a variety of formats, including CSV, TSV, and XML. This allows users to perform their own analysis of the data or to integrate it with other databases.


• API access: The database can be accessed programmatically using a RESTful API. This allows users to automate tasks such as querying the database, retrieving data, and submitting new data.

String-db.org is a valuable resource for researchers in the field of proteomics. It provides a comprehensive, up-to-date database of protein-protein interactions that can be used to study a wide range of biological processes.
