Structure of the Rpn11-Rpn8 dimer reveals mechanisms of substrate deubiquitination during proteasomal degradation
2014
Rpn11, the only essential deubiquitinase (DUB) of the 26S proteasome, sits at the top of the substrate entry pathway and facilitates substrate degradation through cotranslocational deubiquitination. The structure of the Rpn11–Rpn8 complex, together with functional assays, offers insight into Rpn11's promiscuous DUB activity during proteasomal degradation.
