STRING Database Overview STRING is a comprehensive database of known and predicted protein-protein interactions covering 59M proteins and 20B+ interactions across 5000+ organisms. Query interaction networks, perform functional enrichment, discover partners via REST API for systems biology and pathway analysis. When to Use This Skill This skill should be used when: - Retrieving protein-protein interaction networks for single or multiple proteins - Performing functional enrichment analysis (GO, KEGG, Pfam) on protein lists - Discovering interaction partners and expanding protein networks - Test…
