Illustration of evidence underlying predictions for the GO term 'Cell adhesion'. As an assessment of predictive usefulness, the precision at 20% recall (P20R) value based on each single data source is shown in parentheses. (a) Expression levels of annotated genes (dark green) and predictions (orange), grouped by Pearson correlation and complete-linkage hierarchical clustering. (b) Protein domains in common among predictions and annotated genes. (c) Largest protein-protein interaction network among predictions and annotated genes. OPHID, Online Predicted Human Interaction Database. (d) Disease and (e) phenotype annotations in common between predictions and annotated genes. Terminal digits of identifiers are shown in parentheses. OMIM, Online Mendelian Inheritance in Man.
