The nuclear pore complex protein Nup88 is overexpressed in tumor cells.
It has been previously shown (J. Schneider et al., Br. J. Cancer, 77: 1015-1020, 1998) that an antibody directed against Candida albicans proteins (C6) recognizes specifically a protein in human ovarian tumors. We have now performed an immunoscreening of a human cDNA library using this antibody and identified the antigen as Nup88, a protein localized preferentially at the nuclear membrane and p...
متن کاملNuclear pore complex proteins in Alzheimer disease.
Ultrastructural studies of neurofibrillary tangles in Alzheimer disease (AD) have demonstrated a close relationship between nuclear pores and the cytoplasmic paired helical filaments comprising the tangles, as well as nuclear irregularity in many tangle-bearing neurons; nuclear pore aggregation has been observed in nearby neurons. These observations prompted examination of the nuclear pore comp...
متن کاملDisruption of the FG nucleoporin NUP98 causes selective changes in nuclear pore complex stoichiometry and function.
The NUP98 gene encodes precursor proteins that generate two nucleoplasmically oriented nucleoporins, NUP98 and NUP96. By using gene targeting, we have selectively disrupted the murine NUP98 protein, leaving intact the expression and localization of NUP96. We show that NUP98 is essential for mouse gastrulation, a developmental stage that is associated with rapid cell proliferation, but dispensab...
متن کاملNuclear pore complex component MOS7/Nup88 is required for innate immunity and nuclear accumulation of defense regulators in Arabidopsis.
Plant immune responses depend on dynamic signaling events across the nuclear envelope through nuclear pores. Nuclear accumulation of certain resistance (R) proteins and downstream signal transducers are critical for their functions, but it is not understood how these processes are controlled. Here, we report the identification, cloning, and analysis of Arabidopsis thaliana modifier of snc1,7 (m...
متن کاملDeguelin represses both the expression of nucleophosmin and some nucleoporins: Nup88 and Nup214 in Jurkat cells.
Since the first report about cytoplasmic nucleophosmin (NPM) in acute myelogenous leukemia with a normal karyotype was announced, the shuttling activity of NPM and its proper subcellular localization have drawn many attentions. Mechanisms that regulate nucleocytoplasmic transport of proteins may provide novel opportunities for drug development. Here we show that, in Jurkat cells, strong fluores...
