We present experimental results on the translocation of DNA through the NPC of reconstituted nuclei, and discuss the origin of the anomalously slow rate of translocation and the slowing down of entry with time. We then discuss the mystery of protein translocation across the NPC – while small proteins and gold particles go through by passive diffusion, the translocation of large cargoes proceeds only through the formation of even larger cargo-NLS-importin complexes (CIC), that go through the pore without ATP/GTP consumption! We propose a model according to which (a) the NPC is blocked by a protein network (FG Nups) whose open and closed states are separated by a large free energy barrier and (b) the CIC acts as a catalyst that can reduce the barrier and pass through. The results of Brownian dynamics simulations based on this model are presented.
