Scheme of the nuclear pore complex. (a) Cytoplasmic and (b) nucleoplasmic view of the NPC. (c) Illustration of FG-nucleoporin filament in the NPC central channel. (d) Illustration of nucleoporins (Nups) composing a section of the NPC. (e) Vertical section of the NPC: the cytoplasmic ring (CR) is marked in blue, the central ring/spoke ring (SR) is shown in purple, the nucleoplasmic ring (NR) and the nuclear basket filaments are labelled in green. The translocation paths are represented with light blue arrows and the red ones are representative of the secondary channels. Image taken from (Garcia et al. 2016) with permission
