Outline of Final Research Achievements |
We aim to reveal the mechanisms of pathogenesis by elucidating the relationship between a ubiquitin ligase and its substrates. We previously developed a new approach, termed DiPIUS (differential proteomics-based identification of ubiquitylation substrates), to discover substrates of ubiquitin ligases. We revealed that Fbxw7 controls osteoblast and chondrocyte differentiation by targeting OASIS and BBF2H7, basic leucine zipper (bZIP) type transcription factors, for proteasome-mediated degradation. We also showed that DEAD-box RNA helicase DDX24 is a substrate for MDM2. We also showed that Fbxw7 inhibits cancer metastasis in non-cell autonomous manner by targeting Notch for degradation.
