Disease relevance of Nuclear Pore

 

High impact information on Nuclear Pore

  • Known O-GlcNAcylated proteins include cytoskeletal proteins and their regulatory proteins; viral proteins; nuclear-pore, heat-shock, tumor-suppressor, and nuclearoncogene proteins; RNA polymerase II catalytic subunit; and a multitude of transcription factors [6].
  • Biochemical analyses show that Sus1 interacts with SAGA, a large intranuclear histone acetylase complex involved in transcription initiation, and with the Sac3-Thp1 complex, which functions in mRNA export with specific nuclear pore proteins at the nuclear basket [7].
  • Sus1 is a nuclear protein with a concentration at the nuclear pores [7].
  • Genetic studies, immunolocalization, live imaging, and chromatin immunoprecipitation experiments show that these transport proteins block spreading of heterochromatin by physical tethering of the HML locus to the Nup2p receptor of the nuclear pore complex [8].
  • Transport receptors of the Importin beta family shuttle between the nucleus and cytoplasm and mediate transport of macromolecules through nuclear pore complexes [9].
 

Chemical compound and disease context of Nuclear Pore

  • These results are consistent with a model in which Rch1 or another member of the karyopherin-alpha family, through the recognition of the MA NLS, participates in docking the HIV-1 nucleoprotein complex at the nuclear pore [10].
  • An Ad2 capsid component, the penton base, expressed as recombinant protein, was found to be capable of affecting the entire entry pathway of adenovirion in HeLa cells, i.e., cell attachment, endocytosis, vesicular escape, intracytoplasmic movement, and translocation through the nuclear pore complex [11].
  • The temporal and spatial changes of intracellular free calcium ([Ca2+]i) within the cytosol and nucleis of C6 glioma cells have been investigated with laser confocal scanning microscopy to evaluate the current view that Ca2+ ions pass freely through nuclear pores by diffusion [12].
  • The numbers of nuclear pore complexes and tight junctions were quantified in the seminal vesicle epithelial cells of castrated and castrated-plus-androgen-treated male rats, which received subcutaneous pellets of testosterone propionate (1 mg/kg body weight) for 1 week [13].
  • This study was aimed at determining whether hyperoxaluria induces the expression of nuclear pore complex oxalate binding protein p62 which has the transport function [14].

Anatomical context of Nuclear Pore

 

Associations of Nuclear Pore with chemical compounds

  • Biochemically altered nuclear pores specifically lacking the N-acetylglucosamine-bearing pore proteins were constructed in a nuclear assembly extract in order to assign function to these proteins [25].
  • NEs incorporating nuclear pores were assembled around beads coated with the guanosine triphosphatase Ran, forming pseudo-nuclei that actively imported nuclear proteins [26].
  • In this study, we show that all of these autoantibodies are directed against a 210-kD integral membrane glycoprotein of the nuclear pore [22].
  • However, the O-linked GlcNAc moieties are only part of the epitopes recognized, since O-GlcNAc-containing limit pronase fragments of nuclear pore complex proteins cannot be immunoprecipitated by these antibodies [27].
  • Immunoferritin labeling of Triton-treated rat liver nuclei demonstrates that gp 190 occurs exclusively in the nuclear pore complex, in the regions of the cytoplasmic (and possibly nucleoplasmic) pore complex annuli [28].
 

Gene context of Nuclear Pore

  • The NUP1 gene encodes an essential component of the yeast nuclear pore complex [29].
  • Here we show that nuclear-pore-complex extensions formed by the conserved TPR homologues Mlp1 and Mlp2 are responsible for the structural and functional organization of perinuclear chromatin [30].
  • Yra1p interacts directly with the mRNA transport factor Mex67p/Mtr2p, which is associated with the nuclear pore [31].
  • Rip1p is a 42-kD protein associated with nuclear pore complexes and contains nucleoporin-like repeat sequences [32].
  • The export of SSA4 mRNA following stress required functional nuclear pore complexes, as SSA4 mRNA accumulated in nuclei following heat shock of cells containing temperature-sensitive nucleoporins [33].
