  • 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.

Application Abreviews Notes
WB Use a concentration of 0.1 - 0.5 µg/ml. Detects a band of approximately 70 kDa.Can be blocked with Human RanGAP1 peptide (ab22867).

Detects a band of approximately 70 kDa in human brain lysates and 3T3 lysates (predicted MW of 68kDa according to NP_002874).

ICC/IF 1/500.

Target

  • FunctionGTPase activator for the nuclear Ras-related regulatory protein Ran, converting it to the putatively inactive GDP-bound state.
  • Tissue specificityHighly expressed in brain, thymus and testis.
  • Sequence similaritiesBelongs 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 localizationCytoplasm. 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.

  • ab2081 at a concentration of 0.2µg/ml staining approximately 70kda RanGAP1 in 3T3 whole cell lysate (RIPA buffer, 35µg total protein per lane) by Western blot (ECL). Primary incubation = 1 hour.
  • ab2081 (1/500) detecting RanGap1 in mitotic and interphase Hela cells (green). Dapi was used as counterstain in order to highlight the nucleus (blue) and cells were fixed both in Methanol (-20 °C/ 6 mins, followed by 3 washes in PBS) or Paraformaldehyde (3,7% PFA /10 min at room temperature, 0,1% Triton/PBS 5 min, glycine 5 min, followed by 3 washes in PBS); This antibody also gave good results in NIH-3T3 cells under both the above mentioned fixation procedures (data not shown).
