| Biochem/physiol Actions: | WT-1, the product of Wilms’ tumor suppressor gene Wt1, is a nuclear protein with structural motifs characteristic of transcription factors, including four C-terminal zinc fingers. While different pre-mRNA processing could result in 16 isoforms of the protein, the inclusion or exclusion of exon 5 and three amino acids (KTS) between zinc fingers 3 and 4 largely affects the activity of the WT1 protein. Such a complex post-transcriptional regulation, particularly in splicing, may represent a major regulatory mechanism for tumorigenesis of the Wilms’ tumor. With the inclusion of exon 5, WT1 (KTS+) binds to both DNA and RNA and is RNase but not DNase sensitive. This form also co-localizes with splicing factors in a speckled nuclear particle, suggesting that the WT1 protein may function as both a transcription factor and a splicing regulator. |
