Relevance

RanGAP1 is a GTPase activator for the nuclear Ras-related regulatory protein Ran, converting it to the putatively inactive GDP-bound state.
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.

 Western blot - RanGAP1 antibody (ab4784)
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.
