| Outline of Final Research Achievements |
We found that the intracellular localization of SHP2, a key cellular target of the Helicobacter pylori CagA oncoprotein, is regulated by binding with the Hippo signal effectors, TAZ and YAP. We also found that parafibromin, a newly identified SHP2 substrate, acts as a transcriptional scaffold that integrates multiple distinct morphogen signals and converts them into adequate transcriptional outputs.
We identified SHP1 as a phosphatase that dephosphorylates CagA on the EPIYA motifs and thereby neutralizes the oncogenic potential of CagA. Meanwhile Pragmin, a human EPIYA-containing protein, was found to interact with and thereby catalytically activate Csk. H. pylori CagA may additionally promote neoplastic transformation of cells by perturbing the Pragmin-Csk signaling axis.
