Figure 4.

Average cumulative expression coverage in bins of protein families, ordered by size of family. Proteins families for which expression information is available for at least a single member (black) are grouped into bins of at least 35 proteins (total number of families = 1249). Protein families for which expression information is available for at least 75% of the family members (green) are grouped into bins of at least 10 proteins (total number of families = 189). Each point represents a bin. Values on the x-axis describe the size of a family with any expression information (black dots). The size of families with at least 75% expression information (green dots) is the value on top of each green dot.
