The GTP-binding protein Ran/TC4 is required for protein import into the nucleus

open access: closedNature, 1993
Two cytosolic fractions (A and B) from Xenopus oocytes are sufficient to support protein import into the nuclei of digitonin-permeabilized cells. Fraction A recognizes the nuclear localization sequence (NLS) and binds the import substrate to the nuclear envelope, whereas fraction B mediates the subsequent passage of the bound substrate into the nucleus.

Sequence of a plant cDNA from Vicia faba encoding a novel Ran-related GTP-binding protein

open access: closedPlant Molecular Biology, 1994
A clone obtained from a broad bean (Vicia faba) developing cotyledon cDNA library contained the complete coding sequence of a polypeptide with very high homology to the small GTP-binding proteins Ran from human cells and Spi1 from yeast. These proteins belong to the ras superfamily of proteins involved in different basic cellular processes.

Interaction of the Nuclear GTP-Binding Protein Ran with Its Regulatory Proteins RCC1 and RanGAP1

open access: closedBiochemistry, 1995
The guanine nucleotide dissociation and GTPase reactions of Ran, a Ras-related nuclear protein, have been investigated using different fluorescence techniques to determine how these reactions are stimulated by the guanine nucleotide exchange factor RCC1 and the other regulatory protein, RanGAP1 (GTPase-activating protein).

Expression of the Xenopus GTP-binding protein gene Ran during embryogenesis

open access: closedDevelopment Genes and Evolution, 2000
The Ran gene family encodes small GTP binding proteins that are associated with a variety of nuclear processes. We isolated a Xenopus Ran cDNA and analyzed the pattern of expression of this gene during embryogenesis. Ran is expressed maternally and later in the CNS, neural crest, mesenchyme, eyes, and otic vesicles.

Polo-like kinase 1-mediated phosphorylation of the GTP-binding protein Ran is important for bipolar spindle formation

open access: closedBiochemical and Biophysical Research Communications, 2006
Polo-like kinase functions are essential for the establishment of a normal bipolar mitotic spindle, although precisely how Plk1 regulates the spindle is uncertain. In this study, we report that the small GTP/GDP-binding protein Ran is associated with Plk1.

Sequence of a canine cDNA clone encoding a Ran/TC4 GTP-binding protein

open access: closedGene, 1992
We report the isolation and characterization of a canine cDNA encoding a 216-amino acid GTP-binding protein of the Ras superfamily. The protein is almost identical to the human TC4 [Drivas et al., Mol. Cell. Biol. 10 (1990) 1793-1798] and Ran [Bischoff and Ponstingl, Proc. Natl. Acad. Sci.

Conformational States of the Nuclear GTP-Binding Protein Ran and Its Complexes with the Exchange Factor RCC1 and the Effector Protein RanBP1

open access: closedBiochemistry, 1999
It has been shown before by (31)P NMR that Ras bound to the nonhydrolyzable GTP analogue guanosine 5'-O-(beta, gamma-imidotriphosphate) (GppNHp) exists in two conformations which are rapidly interconverting with a rate constant of 3200 s-1 at 30 degrees C [Geyer, M., et al. (1996) Biochemistry 35, 10308-10320].
