GSP1 Protein, S. cerevisiae, Recombinant (His)

GTP-binding protein involved in nucleocytoplasmic transport. Required for the import of protein into the nucleus and also for RNA export. Essential for cell viability. By analogy with Ras, Ran may be activated when GTP is exchanged for bound GDP by RCC1 and inactivated when GTP is hydrolyzed by Ran upon activation by RanGAP1. GSP1 Protein, S. cerevisiae, Recombinant (His) is expressed in yeast with N-6xHis tag. The predicted molecular weight is 26.7 kDa and the accession number is P32835.
