Figure 2From: Microarray analysis of orthologous genes: conservation of the translational machinery across species at the sequence and expression levelProteins localized in the same compartment tend to be expressed at the same time. The plots show the trend for the percentage of genes from the same compartment (%LOC, y-axis) with respect to the total number of genes to which they correlate at a given threshold (CCF, x-axis). The solid lines correspond to the values obtained from the experimental data, whereas the dashed lines are the values expected by chance. The expected trend matches with that of a set of proteins with unknown localization (a), in contrast to sets of proteins with identified compartment: (b) mitochondrion, (c) endoplasmic reticulum, (d) plasma membrane, (e) cytoplasm and (f) nucleus.Back to article page
