| Outline of Final Research Achievements |
Angiogenesis, the formation of new blood vessels, is related to not only development but a variety of diseases like tumor growth/metastasis. Anti-angiogenic drugs are successfully used for cancer therapy. In this study, we identified a novel angiogenic factor, the CUL3/ANKFY1 ubiquitin E3 ligase complex, which determines the cell surface level of integrin, an essential adhesion molecule for angiogenesis. CUL3/ANKFY1 regulated recycling of integrin from endosomes to the plasma membrane in human endothelial cells. The CUL3/ANKFY1 complex might be an attractive protein complex to develop novel anti-angiogenic drugs.
