Wilms Tumor Protein 1 (WT1)

Target
WT1
Molecular classification
Transcription factor, Zinc finger protein, RNA-binding protein
01

Overview

Wilms tumor protein 1 (WT1) is a zinc finger transcription factor crucial for urogenital system development and normal embryonic development. It functions as both a tumor suppressor and an oncogene depending on the cellular context. WT1 regulates genes involved in cell growth, differentiation, apoptosis, and RNA metabolism. Aberrant expression or mutations are implicated in Wilms tumor, Denys–Drash syndrome, and acute myeloid leukemia (AML). WT1 is a significant biomarker for diagnosis and monitoring of AML, and a target for cancer immunotherapies due to its high immunogenicity.
