Research Abstract

In the 1st fiscal year ended March 2013, (1) We found a cancer-derived point mutant of parafibromin functionally mimicking the tyrosine-dephosphorylated parafibromin, which promotes the Wnt signaling pathway through forming a complex with beta-catenin. (2) We identified a nuclear tyrosine kinase that can elevate the tyrosine-phosphorylation of parafibromin.
In the 2nd fiscal year ended March 2014, (3) We found that SHP2 physically interacts with transcriptional co-activators YAP and TAZ, components of the cell-density sensing Hippo signaling pathway. We revealed the YAP/TAZ-dependent regulatory mechanism of the nuclear accumulation of SHP2, which promotes the Wnt signaling pathway through tyrosine-dephosphorylation of parafibromin.
