Function
NU120_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. NUP120 is involved in nuclear poly(A)+ RNA and pre-ribosome export, in GSP1 nuclear import, in NPC assembly and distribution, as well as in nuclear envelope organization.[1] [2] [3] [4] [5]

Publication Abstract from PubMed
Nucleocytoplasmic transport is mediated by nuclear pore complexes (NPCs), enormous protein assemblies residing in circular openings in the nuclear envelope. The NPC is modular, with transient and stable components. The stable core is essentially built from two multiprotein complexes, the Y-shaped heptameric Nup84 complex and the Nic96 complex, arranged around an eightfold axis. We present the crystal structure of Nup120(1-757), one of the two short arms of the Y-shaped Nup84 complex. The protein adopts a compact oval shape built around a novel bipartite alpha-helical domain intimately integrated with a beta-propeller domain. The domain arrangement is substantially different from the Nup85*Seh1 complex, which forms the other short arm of the Y. With the data presented here, we establish that all three branches of the Y-shaped Nup84 complex are tightly connected by helical interactions and that the beta-propellers likely form interaction site(s) to neighboring complexes.
The structure of the scaffold nucleoporin Nup120 reveals a new and unexpected domain architecture.,Leksa NC, Brohawn SG, Schwartz TU Structure. 2009 Aug 12;17(8):1082-91. Epub 2009 Jul 2. PMID:19576787[6]
