Ezrin: Proteins and Enzymes

Ezrin serves as a tyrosine kinase substrate and is phosphorylated in EGF-stimulated cells. It is a cytoplasmic protein enriched in microvilli and other cell surfaces. Ezrin has an actin-binding capacity and is expressed in epithelial cells but not in mesenchymal cells. It is also expressed by certain epithelial tumors, such as renal cell adenocarcinomas.
