The Wilms’ tumour suppressor protein, WT1, undergoes CRM1‐independent nucleocytoplasmic shuttling
2003
The Wilms’ tumour suppressor gene (WT1) encodes a zinc finger-containing nuclear protein essential for kidney and urogenital development. Initially considered a transcription factor, there is mounting evidence that WT1 has a role in post-transcriptional processing. Using the interspecies heterokaryon assay, we have demonstrated that WT1 can undergo nucleocytoplasmic shuttling. We have also mapped the region responsible for nuclear export to residues 182–324. Our data add further complexity to the role of WT1 in trancriptional and post-transcriptional regulation.
