Fig. 1.
Degree distribution and average degrees of four sets of proteins (cancer, non-cancer disease, essential, and control proteins) in four organisms. (A) Human. (B) Fly. (C) Worm. (D) Yeast. Y-axis represents the proportion of proteins having a specific degree. Note that the scale of both the X-axis and Y-axis is not linear. The average degree of each protein set is labeled in vertical line. Red dots denote cancer proteins, green dots denote non-cancer disease proteins, black dots denote essential proteins, and grey dots denote control proteins.
