Figure 8. Distribution of polar clusters along the sequences of FG Nups.
Right) A schematic showing half of the NPC from side-view. FG Nups are divided into three zones with zone1 representing the N-terminus and zone3 representing the C-terminus, which is mostly the structured region of the pore. Left). A heatmap showing abundance of polar clusters in the corresponding region. Brighter areas show higher content of polar clusters. FG Nups can be categorized into three groups. FG Nups of the first group are very rich in polar clusters in their first zone, while FG Nups of the second and third group have more polar clusters in their second and third zones, respectively.
