Guanosine Triphosphate 88-91 Yrb2p Saccharomyces cerevisiae S288C 56-60 25437554-3 2014 Efficient export of NES-cargoes requires Yrb2p (yeast RanBP3), a primarily nuclear protein containing nucleoporin-like phenylalanine-glycine (FG) repeats and a low-affinity Gsp1p-binding domain (RanBD). phenylalanine-glycine 119-140 Yrb2p Saccharomyces cerevisiae S288C 41-46 16143306-1 2005 A Gtr1p GTPase, the GDP mutant of which suppresses both temperature-sensitive mutants of Saccharomyces cerevisiae RanGEF/Prp20p and RanGAP/Rna1p, was presently found to interact with Yrb2p, the S. cerevisiae homologue of mammalian Ran-binding protein 3. Guanosine Diphosphate 20-23 Yrb2p Saccharomyces cerevisiae S288C 183-188 9395535-9 1997 Yrb2p binding to Gsp1p (yeast Ran) as well as to a novel 150-kDa GTP-binding protein is also detected. Guanosine Triphosphate 65-68 Yrb2p Saccharomyces cerevisiae S288C 0-5 9395535-10 1997 The Ran binding domain of Yrb2p is essential for function and for its association with Prp20p and the GTP-binding proteins. Guanosine Triphosphate 102-105 Yrb2p Saccharomyces cerevisiae S288C 26-31 9121474-7 1997 Similar to Yrb1p, Yrb2p bound to GTP-Gsp1p but not to GDP-Gsp1p and enhanced the GTPase-activating activity of Rna1p. Guanosine Triphosphate 33-36 Yrb2p Saccharomyces cerevisiae S288C 18-23 25437554-4 2014 Here, we show that Yrb2p strikingly accelerates the association of Gsp1p-GTP and NES to Xpo1p. Guanosine Triphosphate 73-76 Yrb2p Saccharomyces cerevisiae S288C 19-24 25437554-5 2014 We have solved the crystal structure of the Xpo1p-Yrb2p-Gsp1p-GTP complex, a key assembly intermediate that can bind cargo rapidly. Guanosine Triphosphate 62-65 Yrb2p Saccharomyces cerevisiae S288C 50-55 25437554-6 2014 Although the NES-binding cleft of Xpo1p is closed in this intermediate, our data suggest that preloading of Gsp1p-GTP onto Xpo1p by Yrb2p, conformational flexibility of Xpo1p, and the low affinity of RanBD enable active displacement of Yrb2p RanBD by NES to occur effectively. gsp1p-gtp 108-117 Yrb2p Saccharomyces cerevisiae S288C 132-137 25437554-6 2014 Although the NES-binding cleft of Xpo1p is closed in this intermediate, our data suggest that preloading of Gsp1p-GTP onto Xpo1p by Yrb2p, conformational flexibility of Xpo1p, and the low affinity of RanBD enable active displacement of Yrb2p RanBD by NES to occur effectively. gsp1p-gtp 108-117 Yrb2p Saccharomyces cerevisiae S288C 236-241
