Strength distributions of (a) complex-mode projection and (b) proteins-mode projection (Figure S1). Here, the strength in (a) corresponds to the sum of number of proteins shared with the neighboring complexes for each complex, and the strength (b) corresponds to the sum of number of complexes shared with the neighboring proteins for each protein. The blue squares correspond to the cumulative strength distribution P(s) = ∑s′ s p(s′), and the pink lines and gray curves are the best exponential and power-law fittings, respectively.
