¹Interaction data source (see methods).
²Total number of interaction records found in source.
³Total number of interactions involving only protein interactors.
⁴Number of interactions where all protein interactors were assigned to a ROG (score types 1 to 6). Percentage of column 3 is shown in brackets.
⁵Number of unique protein interactions and complexes (RIGID's) found in the data source (expressed as a percentage of column 4 in brackets).
