Nup358, a Cytoplasmically Exposed Nucleoporin with Peptide Repeats, Ran-GTP Binding Sites, Zinc Fingers, a Cyclophilin A Homologous Domain, and a Leucine-rich Region

Abstract excerpt

The Ras-related nuclear protein, Ran, has been implicated in nuclear transport. By screening a HeLa cell lambda expression library with Ran-GTP and sequencing overlapping cDNA clones, we have obtained the derived primary structure of a protein with a calculated molecular mass of 358 kDa. Using antibodies raised against an expressed segment of this protein, we obtained punctate nuclear surface staining by...
