Deubiquitinase FAM/USP9X Interacts with the E3 Ubiquitin Ligase SMURF1 Protein and Protects It from Ligase Activity-dependent Self-degradation
Oncoprotein MDM2 is a ubiquitin ligase E3 for tumor suppressor p53
A split-site E3 ligase mechanism enables ZNFX1 to ubiquitinate and cluster single-stranded RNA into ubiquitin-coated nucleoprotein particles
