The Usp28 deubiquitinase antagonizes Fbw7-mediated turnover of multiple oncoproteins, including Myc, Jun, and Notch, and promotes tumorigenesis in the intestine. Our recent study reveals that Usp28 also counteracts autocatalytic ubiquitination of Fbw7, suggesting a complex role for Usp28 in the regulation of Fbw7 activity and tumor development.
泛素特异性蛋白酶28（Usp28）去泛素化酶可对抗Fbw7介导的多种癌蛋白（包括Myc、Jun和Notch）的周转，并促进肠道肿瘤发生。我们最近的研究表明，Usp28还可抵消Fbw7的自催化泛素化作用，提示Usp28在Fbw7活性调节和肿瘤发展中发挥复杂作用。
