The RanGTP pathway: from nucleo-cytoplasmic transport to spindle assembly and beyond [PDF]
The small GTPase Ran regulates the interaction of transport receptors with a number of cellular cargo proteins. The high affinity binding of the GTP-bound form of Ran to import receptors promotes cargo release, whereas its binding to export receptors ...

A Novel Class of RanGTP Binding Proteins [PDF]
The importin-alpha/beta complex and the GTPase Ran mediate nuclear import of proteins with a classical nuclear localization signal. Although Ran has been implicated also in a variety of other processes, such as cell cycle progression, a direct function ...

The strategy for coupling the RanGTP gradient to nuclear protein export [PDF]
The Ran GTPase plays critical roles in both providing energy for and determining the directionality of nucleocytoplasmic transport. The mechanism that couples the RanGTP gradient to nuclear protein export will determine the rate of and limits to ...

RanGTP and CLASP1 cooperate to position the mitotic spindle [PDF]
Accurate positioning of the mitotic spindle is critical to ensure proper distribution of chromosomes during cell division. The small GTPase Ran, which regulates a variety of processes throughout the cell cycle, including interphase nucleocytoplasmic ...

Samp1, a RanGTP binding transmembrane protein in the inner nuclear membrane [PDF]
Samp1 is a transmembrane protein of the inner nuclear membrane (INM), which interacts with the nuclear lamina and the Linker of Nucleoskeleton and Cytoskeleton (LINC) complex in interphase and during mitosis, it localizes to the mitotic spindle.

Phosphorylation of maskin by Aurora-A is regulated by RanGTP and importin �� [PDF]
Mitotic spindle assembly in Xenopus egg extracts is regulated at least in part by importin ?? and its regulator, the small GTPase, Ran. RanGTP stabilizes microtubules near the chromosomes during spindle assembly by selectively releasing spindle assembly ...

RanGTP-regulated interactions of CRM1 with nucleoporins and a shuttling DEAD-box helicase [PDF]
CRM1 is an export receptor mediating rapid nuclear exit of proteins and RNAs to the cytoplasm. CRM1 export cargoes include proteins with a leucine- rich nuclear export signal (NES) that bind directly to CRM1 in a trimeric complex with RanGTP.

RanGTP is required for meiotic spindle organization and the initiation of embryonic development inDrosophila [PDF]
RanGTP is important for chromosome-dependent spindle assembly in Xenopus extracts. Here we report on experiments to determine the role of the Ran pathway on microtubule dynamics in Drosophila oocytes and embryos.

Identification of Two novel RanGTP-binding proteins belonging to the importin β superfamily. [PDF]
Nucleo-cytoplasmic transport comprises a large number of distinct pathways, many of which are defined by members of the importin β superfamily of nuclear transport receptors.

The interaction of RNA helicase DDX3 with HIV-1 Rev-CRM1-RanGTP complex during the HIV replication cycle. [PDF]
Molecular traffic between the nucleus and the cytoplasm is regulated by the nuclear pore complex (NPC), which acts as a highly selective channel perforating the nuclear envelope in eukaryotic cells.
