Deubiquitinase FAM/USP9X interacts with the E3 ubiquitin ligase SMURF1 protein and protects it from ligase activity-dependent self-degradation

Xie, Yang and Avello, Monika and Feng, Yan and Schirle, Markus and Bric-Furlong, Eva and Wilson, Christopher and Nathans, Robin and Zhang, Jing and Kirschner, Marc W and Huang, Shih-Min and Cong, Feng (2013) Deubiquitinase FAM/USP9X interacts with the E3 ubiquitin ligase SMURF1 protein and protects it from ligase activity-dependent self-degradation. Journal of Biological Chemistry, 288 (5). pp. 2976-2985. ISSN 0021-9258

Abstract

Background: SMURF1 ubiquitin ligase controls ubiquitination and stability of diverse cellular protein substrates. Results: Deubiquitinase USP9X interacts with SMURF1 and stabilizes SMURF1 through deubiquitination. Conclusion: USP9X is novel regulator of SMURF1 and is required for SMURF1-dependent cellular physiology. Significance: Association between deubiquitinase and ubiquitin ligase may serve as a common strategy to control the cellular protein dynamics through modulating ubiquitin ligase activity. © 2013 by The American Society for Biochemistry and Molecular Biology, Inc.
