The nuclear pore complex (NPC) is huge macromolecular assembly (~30 different nucleoporins, ~50 MDa) in the nuclear envelope that transports cargo between the nucleus and cytoplasm. We study the NPC in yeast and apply genetic, biochemical ,cell biological and structural approaches to unravel the structure and function of this gigantic transport machine. Milestones in this research were the cloning of the first nucleoporin (termed Nsp1), the development of genetic screens on the basis of synthetic lethality to genetically dissect the NPC, the biochemical analysis of the NPC by using powerful affinity-purification methods for nucleoporins and NPC modules, the reconstitution of a seven-subunit containing NPC module and the discovery of a novel structural principle to generate higher order structures within the NPC scaffold with the identification of the dynein light chain as a molecular glue. Future studies involve the structural and functional analysis of the nuclear pore complex including reconstitution of NPC modules into the higher order NPC structure.
