Expression patterns of 1,092 unannotated genes predicted to belong to any of 117 'superGO' categories with 50% confidence or higher. The vertical axis was clustered and diagonalized as in Figure 4. The height of each predicted category has been normalized to facilitate display; the number of genes predicted in each category is indicated at the left. The gene order (vertical axis) has been clustered within each category to illustrate that some categories are characterized by multiple patterns. The proportion (%) of predicted genes in each category that have gene-trap ES cell lines available are represented at right (color scale from 0 to 100%).
