Regulation of p120-catenin nucleocytoplasmic shuttling activity.
P120-catenin is the prototypic member of a subfamily of Armadillo repeat domain (Arm domain) proteins involved in cell-cell adhesion. Interestingly, all members of the p120 subfamily have also been observed in the nucleus, suggesting that they have additional roles that have yet to be determined. Here, we have developed a novel model system for studying the nucleocytoplasmic shuttling capabilit...

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 کاملNucleocytoplasmic shuttling of SOX14A and SOX14B transcription factors
The nucleocytoplasmic shuttling of SOX transcription factors play a crucial role in the regulation of SOX protein functions during development. In this study, we have demonstrated two nuclear localization signals in the HMG box of Eriocheir sinensis SOX14A and SOX14B. These two conserved nuclear localization signals mediate nuclear transport. The N-termini nuclear localization signal mediates t...
متن کاملNucleocytoplasmic Shuttling of Endocytic Proteins
Many cellular processes rely on the ordered assembly of macromolecular structures. Here, we uncover an unexpected link between two such processes, endocytosis and transcription. Many endocytic proteins, including eps15, epsin1, the clathrin assembly lymphoid myeloid leukemia (CALM), and alpha-adaptin, accumulate in the nucleus when nuclear export is inhibited. Endocytosis and nucleocytoplasmic ...
