Mouse functional protein association network from STRING (version 10).


An igraph object that contains a functional protein association network in mouse. The network is extracted from the STRING database (version 10). Only those associations with medium confidence (score>=0.4) are retained.


org.Mm.string <- dRDataLoader(RData = "org.Mm.string")


an object of class "igraph" (see It has attributes for both vertices and edges. Below are attributes for the vertices:

  • name: unique id for the vertices
  • seqid: protein seqid for the vertices
  • geneid: Entrez geneid (if any) for the vertices
  • symbol: gene symbol (if any) for the vertices
  • description: gene description (if any) for the vertices

Below are attributes for the edges:

  • neighborhood_score: predictive score based on neighborhood data
  • fusion_score: predictive score based on fusion data
  • cooccurence_score: predictive score based on cooccurence data
  • coexpression_score: predictive score based on coexpression
  • experimental_score: predictive score based on experimental data
  • database_score: predictive score based on database
  • textmining_score: predictive score based on text mining
  • combined_score: combined score from all above predictive scores
