Outline of Final Research Achievements

We had identified several molecules as a target protein of metastasis suppressor protein Nm23-H1. To clear the mechanism of how cancer cells were obtained ability of migration, we investigated the relationship between Nm23-H1 and candidate of binding proteins which we identified previously. ①Asef2 was identified as a target protein of Nm23-H1, which was stimulated by adenomatous polyposis coli. The GEF activity of Asef was enhanced in scirrhous type gastric carcinoma cell lines and then led to high migration activities, however exogenous Nm23-H1 again suppressed GEF activity. ②G3BP1, 2a and 2b (G3BPs) that are associated with breast cancer and pancreatic cancer, were also bound to Nm23-H1, but there was a difference in the binding strength. Each G3BP molecules have different functions. G3BP1 is known to associate with stress granules formation. Co-transfected cells of G3BPs and Nm23-H1 showed co-localization in the cytoplasm as punctate signals and in all cases.
