Nucleocytoplasmic Shuttling Factors Including Ran and CRM1 Mediate Nuclear Export of NFAT In Vitro
We have developed a permeabilized cell assay to study the nuclear export of the shuttling transcription factor NFAT, which contains a leucine-rich export signal. The assay uses HeLa cells that are stably transfected with NFAT fused to the green fluorescent protein (GFP). Nuclear export of GFP-NFAT in digitonin-permeabilized cells occurs in a temperature- and ATP-dependent manner and can be quan...
متن کاملCRM1- and Ran-independent nuclear export of β-catenin
Background: Activation of the Wnt pathway induces -catenin to localize Address: Max-Planck-Institute for Developmental Biology, Department of Cell Biology, Tübingen inside the nucleus, where it interacts with transcription factors such as D-72076, Germany. TCF/LEF-1. Regulation of the pathway occurs through a -catenin– degrading complex based on Axin and the tumor suppressor APC. We have Corres...
متن کاملNucleocytoplasmic shuttling by nucleoporins Nup153 and Nup214 and CRM1-dependent nuclear export control the subcellular distribution of latent Stat1
Interferon stimulation of cells leads to the tyrosine phosphorylation of latent Stat1 and subsequent transient accumulation in the nucleus that requires canonical transport factors. However, the mechanisms that control the predominantly cytoplasmic localization in unstimulated cells have not been resolved. We uncovered that constitutive energy- and transport factor-independent nucleocytoplasmic...
متن کاملFacilitated nucleocytoplasmic shuttling of the Ran binding protein RanBP1.
The Ran binding protein RanBP1 is localized to the cytosol of interphase cells. A leucine-rich nuclear export signal (NES) near the C terminus of RanBP1 is essential to maintain this distribution. We now show that RanBP1 accumulates in nuclei of cells treated with the export inhibitor, leptomycin B, and collapse of the nucleocytoplasmic Ran:GTP gradient leads to equilibration of RanBP1 across t...
متن کاملA deep proteomics perspective on CRM1-mediated nuclear export and nucleocytoplasmic partitioning
CRM1 is a highly conserved, RanGTPase-driven exportin that carries proteins and RNPs from the nucleus to the cytoplasm. We now explored the cargo-spectrum of CRM1 in depth and identified surprisingly large numbers, namely >700 export substrates from the yeast S. cerevisiae, ≈1000 from Xenopus oocytes and >1050 from human cells. In addition, we quantified the partitioning of ≈5000 unique protein...
