The Nup and SUMO E3-ligase Nup358/RanBP2 are the major components of the cytoplasmic filaments of the NPC. In this study, we perform a structure-function analysis of Nup358 and describe its role in nuclear import of specific proteins.
Nup358, a nucleoporin, functions as a key determinant of the …
In the present study, we evaluate changes in the expression levels of several nucleoporins and show that the amount of Nup358/RanBP2 within individual NPCs increases during muscle differentiation in C2C12 cells.
Nucleoporin Nup358 drives the differentiation of myeloid-biased …
2024年6月5日 · We report that Nup358, a nucleoporin linked to several myeloid disorders, is required for the developmental progression of early myeloid progenitors.
The Nup358-RanGAP Complex Is Required for Efficient Importin …
2008年2月27日 · Here, we investigate the roles of the Nup358-RanGAP1 complex and of soluble RanGAP1 in nuclear protein transport, combining in vivo and in vitro approaches. Depletion of Nup358 by RNA interference led to a clear reduction of importin α/β-dependent nuclear import of various reporter proteins.
The nuclear pore component Nup358 promotes transportin-dependent ...
2009年4月15日 · Nup358 (also known as RanBP2), a component of the cytoplasmic filaments of the nuclear pore complex, has been implicated in various nucleocytoplasmic transport pathways. Here, we identify Nup358 as an important factor for transportin-mediated nuclear import.
The Nucleoporin Nup358/RanBP2 Promotes Nuclear Import in a …
In this study, we perform a structure–function analysis of Nup358 and describe its role in nuclear import of specific proteins. In a screen for nuclear proteins that accumulate in the cytoplasm upon Nup358 depletion, we identified proteins that were able to interact with Nup358 in a receptor-independent manner.
Nup358/RanBP2 Attaches to the Nuclear Pore Complex via …
Transmission electron microscopy (TEM) analysis of purified Nup358/RanBP2 revealed a ∼36-nm filamentous structure, and depletion of Nup358 from Xenopus egg extracts caused assembly of NPCs lacking detectable cytoplasmic filaments, indicating Nup358 as a major, and possibly the only, nucleoporin constituent of these filaments (12, 64). No ...
Nup358, a Cytoplasmically Exposed Nucleoporin with Peptide …
Electron microscopy of immunogold-decorated rat liver nuclear envelopes sublocalized the 358-kDa protein at (or near) the tip of the cytoplasmic fibers of the nuclear pore complex (NPC). In agreement with current convention, this protein was therefore termed Nup358 (for nucleoporin of …
Nucleoporin Nup358 drives the differentiation of myeloid-biased ...
We report that Nup358, a nucleoporin linked to several myeloid disorders, is required for the developmental progression of early myeloid progenitors.
Nup358 contains a leucine-rich region, four potential Ran binding sites (i.e. Ran binding protein 1 homologous domains) flanked by nucleoporin-characteristic FXFG or FG repeats, eight zinc finger motifs, and a C-terminal cyclophilin A homologous do-main.
