Report the ubiquitin-bound structure of Rpn11 from S. cerevisiae and the mechanisms for mechanochemical coupling of substrate degradation and deubiquitination.
Title: An AAA Motor-Driven Mechanical Switch in Rpn11 Controls Deubiquitination at the 26S Proteasome.
A key role for rpn11 in 26S proteasome
Title: Base-CP proteasome can serve as a platform for stepwise lid formation.
Fluorescently labeled tetra-Ub chains revealed endo-chain preference for Ubp6 acting on Lys(48) and random action for Rpn11.
Title: Disassembly of Lys11 and mixed linkage polyubiquitin conjugates provides insights into function of proteasomal deubiquitinases Rpn11 and Ubp6.
Overall, this work demonstrates that the co-opted Rpn11p, which is involved in the assembly of the functional proteasome, also functions in the proper assembly of the tombusvirus viral replicase complex.
Title: The proteasomal Rpn11 metalloprotease suppresses tombusvirus RNA recombination and promotes viral replication via facilitating assembly of the viral replicase complex.
Rpn11-Rpn8 interaction occurs via two distinct interfaces; Rpn11 lacks a conserved surface to bind the ubiquitin Ile44 patch
Title: Structure of the Rpn11-Rpn8 dimer reveals mechanisms of substrate deubiquitination during proteasomal degradation.
The Rpn11 active site at the entrance to the ATPase ring pore is likely to prevent erroneous deubiquitylation of folded proteins.
Title: Crystal structure of the proteasomal deubiquitylation module Rpn8-Rpn11.
Data show that the availability of Rpn11 is important for maintaining adequate levels of intact proteasomes, as its depletion caused growth and proteolytic defects in rpn3.
Title: A proteasome assembly defect in rpn3 mutants is associated with Rpn11 instability and increased sensitivity to stress.
The authors analyzed the rpn11-m1 phenotypes and found that overexpression of Cdc14 suppresses all the rpn11-m1 defects, including the mitochondrial ones.
Title: Analysis of the rpn11-m1 proteasomal mutant reveals connection between cell cycle and mitochondrial biogenesis.
It is conceivable that Rpn10/Rpn11 interaction couples proteasome assembly to substrate binding.
