Proteins with Values/Ranks - Functional Enrichment Analysis
Submit your entire experiment as a list of proteins - no cutoffs.
Behind each protein, put a meaningful value for ranking (fold-change, log-pvalue, abundance, ...).

Geneset by Pathway / Process / Disease / Publication
Search for any pathway name and visualize its proteins as a STRING network. You can query any identifier or a keyword matching, among others, Gene Ontology terms, KEGG pathways, and diseases, but also published manuscripts that may discuss groups of genes.

Add any organism to STRING / Annotate proteome
Upload a complete species proteome to STRING, and we'll generate its interaction network and predict protein functions, including Gene Ontology terms and KEGG pathways. Once uploaded, you can explore and analyze your proteome data through our web interface, access it programmatically via API, or download all predictions in bulk.

Examples and Highlights

Example 1

showFAA4 and its ten most confident interactors.
FAA4 in yeast is a long chain fatty acyl-CoA synthetase; see it connected to other synthetases as well as regulators.
 

Example 2

showThe 20 most frequently mutated human cancer genes.
These have a higher-than-expected degree of interconnectivity, and are enriched in characteristic molecular functions.
 

Example 3

showA poorly characterized protein from Natronococcus.
It has no annotated domains or functions, but shows some intriguing connections to possible DNA-replication or -repair proteins.
