Structure of LNX1:Ubc13~Ubiquitin Complex Reveals the Role of Additional Motifs for the E3 Ligase Activity of LNX1

LNX1 (ligand of numb protein-X1) is a RING and PDZ domain-containing E3 ubiquitin ligase that ubiquitinates human c-Src kinase. Here, we report the identification and structure of the ubiquitination domain of LNX1, the identification of Ubc13/Ube2V2 as a functional E2 in vitro, and the structural an...
