Figure 4From: PCDq: human protein complex database with quality index which summarizes different levels of evidences of protein complexes predicted from H-Invitational protein-protein interactions integrative datasetRelationship between complexes and subunits. (a) The relationship between complex size (number of different protein subunits of each category; X-axis) and frequency (Y-axis). (b) Percentage of category I and II protein occupancy of the annotated complexes.Back to article page
