Table 2 A summary of protein interaction and GO annotation data used in the external validation of the hub classifiers.

# of proteins

# of hubs (10% of total proteins)

# of non-hubs (90% of total proteins)

# of protein interactions

minimum # of interactions per hub

# of proteins with at least one GO term

# of proteins without any GO term

% of proteins with at least one GO term

# of different GO terms – process
