wt1 proteins

Summary

Summary: Isoforms encoded by the WT1 Wilms tumor suppressor gene (GENES, WILMS TUMOR) and produced by alternative splicings. They are zinc finger-containing transcription factors involved in both transactivation and repression, and are critical for normal development and function of the urogenital tract.
