An extended conformation for K48 ubiquitin chains revealed by the hRpn2: Rpn13: K48-diubiquitin structure

X Lu, DL Ebelle, H Matsuo, KJ Walters - Structure, 2020 - cell.com
Rpn13/Adrm1 is recruited to the proteasome by PSMD1/Rpn2, where it serves as a
substrate receptor that binds preferentially to K48-linked ubiquitin chains, an established …
