 The integrated human protein interaction network (CRG-all) analyzed in this study.  
Column 1: interacting protein 1 (Ensembl gene id)
Column 2: interacting protein 2 (Ensembl gene id) 
Column 3: experimental binding evidence for interaction
Column 4: any supporting evidence for interaction 
Column 4: PUBMED IDs (PMIDs) of publications reporting the interaction
Column 5: interaction databases reporting the interaction (references for databases are listed in table 1)  
Columns 6-85: the cells and tissues in which the interaction can occur because both genes are detected as expressed (1) or not (0) using the GNF Atlas (Su et al. 2004) and a threshold of 200 for expression
