A tri-ionic anchor mechanism drives Ube2N-specific recruitment and K63-chain ubiquitination in TRIM ligases

The E3 ligase TRIM21 targets a broad range of pathogenic proteins using a unique mechanism. Here, the authors combine structural, biochemical and cell biological approaches to elucidate how TRIM21 selectively recruits its canonical E2 partner enzyme Ube2N and catalyzes ubiquitination.
