NPC components, collectively referred to as nucleoporins (NUPs), can play the role of both NPC structural components and of docking or interaction partners for transiently associated nuclear transport factors. NIC96, which is localized to the core of the NPC and the distal ring of the nuclear basket, is required for de novo assembly of NPCs.

| - | The nuclear pore complex (NPC) is an elaborate protein machine that mediates macromolecular transport across the nuclear envelope in all eukaryotes. The NPC is formed by nucleoporins that assemble in multiple copies around an 8-fold symmetry axis. Homology modeling suggests that most architectural nucleoporins are composed of simple beta-propeller and alpha-helical repeat domains. Here we present the crystal structure of Nic96, the Nup93 homolog in Saccharomyces cerevisiae, one of the major components of the NPC. This is the first structure of an alpha-helical nucleoporin domain. The protein folds into an elongated, mostly alpha-helical structure. Characteristically, non-canonical architectural features define the Nic96 structure. Sequence conservation among Nup93 homologs across all eukaryotes strongly suggests that the distinct topology is evolutionarily well maintained. We propose that the unique Nic96/Nup93 fold has a conserved function in all eukaryotes. | ||
