When to Use

You have gene symbols (e.g., TP53) and need to resolve them to STRING protein identifiers for downstream analysis.
You want to retrieve a protein–protein interaction (PPI) network (functional/physical) with confidence scores for one or more proteins.
You need to find interaction partners for a target protein to expand a candidate list (e.g., add top N neighbors).
You want to perform functional enrichment (GO/KEGG/Reactome, etc.) for a protein set to interpret biological themes.
You need a quick static visualization (PNG/SVG) of a STRING network for reports or notebooks.

Key Features

ID Mapping: Convert gene/protein names to STRING identifiers for a given organism.
Network Retrieval: Fetch interaction edges with confidence scores from STRING.
Interaction Partners: Expand a protein list by retrieving interaction partners.
Enrichment Analysis:
- Functional enrichment (e.g., GO, KEGG, Reactome)
- PPI enrichment statistics
- Functional annotations (e.g., PFAM/SMART where supported by STRING endpoints)
Visualization: Download static network images (PNG/SVG).
