Transport receptor occupancy in nuclear pore complex mimics

Nuclear pore complexes (NPCs) regulate all molecular transport between the nucleus and the cytoplasm in eukaryotic cells. Intrinsically disordered Phe-Gly nucleoporins (FG-Nups) line the central conduit of NPCs to impart a selective barrier where large proteins are excluded unless bound to a transport receptor (karyopherin; Kap). Here, we...

Towards a bottom-up reconstitution of the nuclear pore complex

At first glance nanopores may appear simple, almost intuitive, to understand given that they are, quite literally, ‘just’ very small pores in a membrane. In fact, one may even wonder why at all we need trained scientists to study such seemingly simple entities. The short answer is that nanopores, as the word suggests, are nanoscale entities and,...
