Function

[NIC96_YEAST] Functions as a component of the nuclear pore complex (NPC). 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. It is involved in nuclear GSP1 import.^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7] ^[8] ^[9] ^[10] ^[11]

Publication Abstract from PubMed

Nic96 is a conserved nucleoporin that recruits the Nsp1-Nup49-Nup57 complex, a module with Phe-Gly (FG) repeats, to the central transport channel of the nuclear pore complex (NPC). Nic96 binds the Nsp1 complex via its N domain and assembles into the NPC framework via its central and C domain. Here, we report the crystal structure of a large structural nucleoporin, Nic96 without its N domain (Nic96DeltaN). Nic96DeltaN is composed of three domains and is a straight molecule that--although almost entirely helical--exhibits strong deviations from the predicted alpha-solenoid fold. The missing N domain projects midway from the Nic96 molecule, indicating how the Nsp1 complex might be located with respect to the rod-like Nic96. Notably, Nic96DeltaN binds in vitro to FG repeats of the Nsp1 complex. These data suggest a model of how Nic96 could organize a transport module with coiled-coil domains and FG repeats in the central pore channel.
