    PHYSICAL PROPERTIES
    STRUCTURE
    motifs/domains
  • a minimal CTE binding domain with a RNP-type RNA binding domain (RBD) and four leucine-rich repeats
  • a nucleoporin binding domain with a NTF2-like domain
  • an ubiquitin-associated (UBA) domain that helps in coordinating transcription elongation and nuclear export by interacting both with ubiquitin conjugates and specific targets, such as THOC1, a component of the THO complex
  • HOMOLOGY
    Homologene
    FAMILY
  • NXF family
  • CATEGORY transport carrier
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,nucleus,nucleoplasm,nuclear bodies,nuclear speckles
    text at both the nucleoplasmic and cytoplasmic faces
    of the nuclear pore complex; shuttles between the nucleus and
    the cytoplasm
    basic FUNCTION
  • involved 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
  • NXF1/NXT1 heterodimer enhances nucleoporin binding and induces the formation of a NXF1/NXT1/nucleoporin ternary complex that is likely to be a key intermediate in the process of nuclear mRNA export

    PATHWAY
    metabolism
    signaling
    a component
  • heterodimerizing with NXT1
  • part of NXF1 export pathway
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interaction with THOC1 is required for NXF1-UBA domain to bind polyubiquitin, possibly by inducing an H4-dependent conformational change
  • interaction of RBM15B and RBM15 with NXF1 via their C-terminal regions
  • association with THRAP3
  • TPR plays an important role in quality control of mRNA trafficked on the NXF1 pathway
  • U2AF2 protein facilitates RNA nuclear export by facilitating the formation of a messenger ribonucleoprotein export complex that contains both the NXF1 receptor and the RNA substrate
  • SUN1 functions in mammalian mRNA export through the NXF1-dependent pathway, and this interaction SUN1-NXF1is at least partly regulated by a protein kinase C (PKC)
