  • General notes


    Ran is a small signaling GTPase that is involved in nucleocytoplasmic transport. Two additional functions of animal Ran in the formation of spindle asters and the reassembly of the nuclear envelope in mitotic cells have been recently reported. In contrast to Ras or Rho, Ran is not associated with membranes. Instead, the spatial sequestering of its accessory proteins, the Ran GTPase-activating protein RanGAP 1 and the nucleotide exchange factor RCC1, appears to define the local concentration of RanGTP vs. RanGDP involved in signaling. Mammalian RanGAP 1 is bound to the nuclear pore by a mechanism involving the attachment of small ubiquitin-related modifier protein (SUMO) to its C terminus and the subsequent binding of the SUMOylated domain to the nucleoporin Nup358.

Target

  • Function
    GTPase activator for the nuclear Ras-related regulatory protein Ran, converting it to the putatively inactive GDP-bound state.
  • Tissue specificity
    Highly expressed in brain, thymus and testis.
  • Sequence similarities
    Belongs to the RNA1 family.
    Contains 6 LRR (leucine-rich) repeats.
  • Post-translational
    modifications
    Phosphorylated occurs before nuclear envelope breakdown and continues throughout mitosis. Phosphorylated by the M-phase kinase cyclin B/Cdk1, in vitro. Differential timimg of dephosphorylation occurs during phases of mitosis. The phosphorylated form remains associated with RANBP2/NUP358 and the SUMO E2-conjugating enzyme, UBC9, on nuclear pore complex (NPC) diassembly and during mitosis.
    Sumoylated with SUMO1. Sumoylation is necessary for targeting to the nuclear envelope (NE), and for association with mitotic spindles and kinetochores during mitosis. Also required for interaction with RANBP2 and is mediated by UBC9.
  • Cellular localization
    Cytoplasm. Nucleus membrane. Chromosome, centromere, kinetochore. Cytoplasm, cytoskeleton, spindle pole. Cytoplasmic during interphase. Targeted to the nuclear rim after sumoylation. During mitosis, associates with mitotic spindles. Association with kinetochores appears soon after nuclear envelope breakdown and persists until late anaphase. Mitotic location also requires sumoylation.

Images

  • ab4784 staining RanGAP1 on skin tissue by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) 

  • ab4784 at a 1/500 dilution staining approximately 90kDa RanGAP 1 in Xenopus egg extract (lane X, 50µg per lane) and HeLa total cell extract (lane Hu, 50µg per lane) by western blot (ECL, 1 minute exposure).

    NB: RanGAP 1 in the above blot is modified by the addition of the SUMO-modifier peptide, so runs at approximately 90 kDa. The smaller band visible in the Xenopus lane at approximately 60 kDa is likely to be a small amount of non-SUMOylated protein.
