Box plot of gene expression profile similarity and the number of protein subunits in a complex. The y-axis indicates gene expression similarity (negative logarithm of p-value of average cosine of gene expression profiles) in a complex; a higher value means that the subunits of the complex show greater similarity in their gene expression profiles. The x-axis indicates the number of protein subunits with expression data in the complex. The gene expression profiles similarity increases with the number of proteins.
