Outline of Final Research Achievements |
Platelet activation receptor CLEC-2 binds to podoplanin expressed on the surface of several kinds of cancer cells, which facilitates cancer metastasis. Therefore, anti-CLEC-2 drugs are expected to have anti-platelet and anti-metastatic effects. We focused on snake venom rhodocytin as its drug discovery source. In order to verify the binding site of rhodocytin with CLEC-2 and the formation mechanism of the complex, recombinant wild-type and mutant rhodocytin were produced with mammalian cell line. As a result, we found mutant rhodocytin with anti-CLEC-2 effect. In the mouse model, this mutant rhodocytin strongly inhibited podoplanin-dependent cancer metastasis without inducing platelet aggregation.
