The distribution of Moesin (show MSN ELISA Kits) in the nucleus suggests a function in transcription and the depletion of mRNA export factors Nup98 or its interacting partner, Rae1 (show RAE1 ELISA Kits), leads to the nuclear accumulation of Moesin (show MSN ELISA Kits), suggesting that the nuclear function of the protein is linked to mRNA export
Nup98 provides a scaffold for poised genes and mediates Induced enhancer-promoter contacts in genetic transcription.
Nup98 associates and colocalizes with the MBD (show DPEP1 ELISA Kits)-R2/NSL and Trx (show GSR ELISA Kits) complexes. Nup98 regulates transcription of Trx (show GSR ELISA Kits) targets, the Hox (show MSH2 ELISA Kits) genes.
Nup98, a virus-induced gene, was antiviral against a panel of viruses.
Study analyzed genomic interactions of full-length nucleoporins Nup98, Nup50 (show NUP50 ELISA Kits), and Nup62 and found that they predominantly interacted with active genes inside the nucleoplasm, particularly those involved in developmental regulation and the cell cycle.
Nup88 (show NUP88 ELISA Kits) localizes to silent loci, Sec13 (show SEC13 ELISA Kits), Nup98, and a subset of FG-repeat nucleoporins bind to developmentally regulated genes undergoing transcription induction.
We demonstrated that Nup98-TopIIbeta and Nup98-SETBP1 (show SETBP1 ELISA Kits) negatively regulate the XPO1 (show XPO1 ELISA Kits)-mediated protein export. Our results will contribute to the understanding of the molecular mechanism by which the Nup98-fusion proteins induce tumorigenesis.
The age-associated accumulation of somatic mutations that occurs in the Nup98-HOXD13 (show HOXD13 ELISA Kits) (NHD13) mouse model of leukemia progression was significantly elevated by co-expression of a PKR (show EIF2AK2 ELISA Kits) transgene.
Nup50 (show NUP50 ELISA Kits) dynamics are independent of importin alpha, Nup153 (show NUP153 ELISA Kits), and Nup98, even though the latter two proteins also exhibit transcription-dependent mobility.
Data indicate that loss of cyclin-dependent kinase inhibitor p15 (p15Ink4b (show CDKN2B ELISA Kits)) collaborates with oncogene (show RAB1A ELISA Kits) fusion protein Nup98-HoxD13 (show HOXD13 ELISA Kits) transgene in the development of predominantly myeloid neoplasms.
Homeobox (show PRRX1 ELISA Kits) partners create more potent NUP98 fusion oncogenes than do non-homeobox (show PRRX1 ELISA Kits) partners.
findings show that expression of NUP98-HOXD13 (show HOXD13 ELISA Kits) impairs class switch recombination and reduces the antibody-mediated immune response, in addition to its role in leukemia
Mice expressing both the FLT3 (show FLT3 ELISA Kits)/ITD and Nup98-HoxD13 (show HOXD13 ELISA Kits) (NHD13) fusion gene developed acute myeloid leukemia (show BCL11A ELISA Kits) with 100% penetrance
Data show that NUP98-HOXA10HD, a novel, canonical NUP98-Hox (show MSH2 ELISA Kits) fusion, significantly enhances the self-renewal capacity of hematopoietic stem cells.
These results clearly demonstrate that Nup98 functions as a novel shuttling cofactor for Crm1 (show XPO1 ELISA Kits)-mediated nuclear export in conjunction with RanBP3 (show RANBP3 ELISA Kits).
A mouse model of CML blast crisis induced by cooperation between BCR/ABL (show ABL1 ELISA Kits) and NUP98/HOXA9 (show HOXA9 ELISA Kits)
data show that a novel nup98 was identified and it serves a role in nucleocytoplasmic trafficking similar to human NUP98.
Importantly, binding of Nup98 to DHX9 stimulates the ATPase activity of DHX9, and a transcriptional reporter assay suggests Nup98 supports DHX9-stimulated transcription.
The second FG repeat domain of the NUP98 moiety of the NUP98-HOXA9 (show HOXA9 ELISA Kits) fusion protein is important for its cell immortalization and leukemogenesis activities. NUP98-HOXA9 (show HOXA9 ELISA Kits) interacts with mixed lineage leukemia (MLL (show MLL ELISA Kits)) via this FG repeat domain and that, in MLL (show MLL ELISA Kits)-null mice, NUP98-HOXA9 (show HOXA9 ELISA Kits)-induced cell immortalization and leukemogenesis are severely inhibited.
DYNLT1 (show DYNLT1 ELISA Kits) interacts with nucleoporins and plays a role in the dysregulation of gene expression and induction of hematopoietic cell proliferation by the leukemogenic nucleoporin (show AGFG2 ELISA Kits) fusion, NUP98-HOXA9 (show HOXA9 ELISA Kits)
the mutation order in the NUP98-rearranged pediatric AML (show RUNX1 ELISA Kits) begins with the NUP98 rearrangement leading to epigenetic dysregulations then followed by mutations of critical hematopoietic transcription factors and finally, activation of the FLT3 (show FLT3 ELISA Kits) signaling pathway.
These results provide novel insight into the mechanisms underlying the aberrant capability of NUP98 oncoproteins to interact with APC (show APC ELISA Kits)/C(Cdc20 (show CDC20 ELISA Kits)) and to interfere with its function.
Our results suggest that NA10HD increases the number of gamma-globin-transduced HSCs that engraft, leading to an elevated number of fetal hemoglobin-containing red cells.
NUP98-HOXA9 (show HOXA9 ELISA Kits) ability to induce blood cell expansion is evolutionarily conserved.
The study demonstrated the association of NUP98-IQCG with CRM1, and found that NUP98-IQCG expression inhibits the CRM1-mediated nuclear export of p65 and enhances the transcriptional activity of nuclear factor-kappaB. Moreover, IQCG could be entrapped in the nucleus by NUP98-IQCG, and the fusion protein interacts with calmodulin via the IQ motif in a calcium-independent manner.
The results indicate that highly selective targeting of Nup98-fusion proteins to Hox (show MSH2 ELISA Kits) cluster regions via prebound Crm1 (show XPO1 ELISA Kits) induces the formation of higher order chromatin structures that causes aberrant Hox (show MSH2 ELISA Kits) gene regulation.
Despite the difference in localization, all tested Nup98 chimera provoked morphological alterations in the nuclear envelope (NE), in particular affecting the nuclear lamina and the lamina-associated polypeptide 2alpha.
These data support a model in which Nup98 interacts with microtubules and antagonizes MCAK (show KIF2C ELISA Kits) activity, thus promoting bipolar spindle assembly.
Signal-mediated nuclear import and export proceed through the nuclear pore complex (NPC), which is comprised of approximately 50 unique proteins collectively known as nucleoporins. The 98 kDa nucleoporin is generated through a biogenesis pathway that involves synthesis and proteolytic cleavage of a 186 kDa precursor protein. This cleavage results in the 98 kDa nucleoporin as well as a 96 kDa nucleoporin, both of which are localized to the nucleoplasmic side of the NPC. Rat studies show that the 98 kDa nucleoporin functions as one of several docking site nucleoporins of transport substrates. The human gene has been shown to fuse to several genes following chromosome translocations in acute myelogenous leukemia (AML) and T-cell acute lymphocytic leukemia (T-ALL). This gene is one of several genes located in the imprinted gene domain of 11p15.5, an important tumor-suppressor gene region. Alterations in this region have been associated with the Beckwith-Wiedemann syndrome, Wilms tumor, rhabdomyosarcoma, adrenocortical carcinoma, and lung, ovarian, and breast cancer. Alternative splicing of this gene results in several transcript variants\; however, not all variants have been fully described.
