Identification of ptpro as a novel target gene of Wnt signaling and its potential role as a receptor for Wnt.

摘要
Wnt/β-catenin signaling plays critical roles in embryonic development and tissue homeostasis in adults by controlling the expression of target genes. We found that expression of ptpro, which encodes a protein tyrosine phosphatase receptor type O (PTPRO), was induced by Wnt/β-catenin signaling in a T cell factor/lymphoid enhancer factor dependent manner. Biochemical assays found that PTPRO interacted with Wnt via its extracellular domain. In addition, ectopic expression of this extracellular domain inhibited Wnt-mediated reporter activity. These results suggest that ptpro is a target gene of Wnt/β-catenin signaling and that PTPRO may function as a novel receptor for Wnt.
