Target

  • FunctionInvolved in the nuclear export of mRNA species bearing retroviral constitutive transport elements (CTE) and in the export of mRNA from the nucleus to the cytoplasm. The NXF1-NXT1 heterodimer is involved in the export of HSP70 mRNA in conjunction with THOC4 and THOC5.
  • Tissue specificityExpressed ubiquitously.
  • Sequence similaritiesBelongs to the NXF family.
    Contains 4 LRR (leucine-rich) repeats.
    Contains 1 NTF2 domain.
    Contains 1 RRM (RNA recognition motif) domain.
    Contains 1 TAP-C domain.
  • DomainThe minimal CTE binding domain consists of an RNP-type RNA binding domain (RBD) and leucine-rich repeats.
    The nucleoporin binding domain consists of a NTF2 domain (also called NTF2-like domain) and a TAP-C domain (also called UBA-like domain). It has 2 nucleoporin-FG-repeats binding sites (one in the NTF2 and the other in the TAP-C domain) which contribute to nucleoporin association and act synergistically to export cellular mRNAs.
    The NTF2 domain is functional only in the presence of NXT1 and is essential for the export of mRNA from the nucleus.
    The TAP-C domain mediates direct interactions with nucleoporin-FG-repeats and is necessary and sufficient for localization of NXF1 to the nuclear rim. The conserved loop 594-NWD-596 of the TAP-C domain has a critical role in the interaction with nucleoporins.
    The leucine-rich repeats are essential for the export of mRNA from the nucleus.
    The RNA-binding domain is a non-canonical RNP-type domain.
  • Cellular localizationNucleus > nucleoplasm. Nucleus speckle. Cytoplasm. Localized predominantly in the nucleoplasm and at both the nucleoplasmic and cytoplasmic faces of the nuclear pore complex. Shuttles between the nucleus and the cytoplasm. Travels to the cytoplasm as part of the exon junction complex (EJC) bound to mRNA.

  • Anti-NXF1 antibody [53H8] (ab50609) at 0.5 µg/ml + Hela nuclear cell extract at 200 µg/ml

    Predicted band size : 70 kDa
    Observed band size : 62 kDa (why is the actual band size different from the predicted?)
  • ab50609 staining NXF1 in HeLa cells by Immunocytochemistry/ Immunofluorescence. Cells were fixed in paraformaldehyde and permeabilized in 0.1% Triton X-100. The primary antibody was diluted 1/1000 in 3% BSA in PBS and incubated with the sample for 1 hour at 25°C. The secondary antibody was Alexa Fluor® 568-conjugated goat anti-mouse polyclonal, diluted 1/1000. DAPI was used for nuclear counterstain.
