Maintaining proteome integrity is essential for long-term viability of all organisms and is
overseen by intrinsic quality control mechanisms. The secretory pathway of eukaryotes …

Misfolded, potentially toxic proteins in the lumen and membrane of the endoplasmic
reticulum (ER) are eliminated by proteasomes in the cytosol through ER-associated …

Endoplasmic reticulum (ER)-associated degradation (ERAD) and the unfolded protein
response (UPR) are two key quality-control machineries in the cell. ERAD is responsible for …

Protein folding is inherently error prone, especially in the endoplasmic reticulum (ER). Even
with an elaborate network of molecular chaperones and protein folding facilitators …

Ubiquitin E3 ligases control every aspect of eukaryotic biology by promoting protein
ubiquitination and degradation. At the end of a three-enzyme cascade, ubiquitin ligases …

The endoplasmic reticulum (ER) is a large, dynamic, and multifunctional organelle. ER
protein homeostasis is essential for the coordination of its diverse functions and depends on …

Misfolded proteins of the endoplasmic reticulum (ER) are discarded by a conserved process,
called ER-associated protein degradation (ERAD). ERAD substrates are retro-translocated …

INTRODUCTION Protein homeostasis in the endoplasmic reticulum (ER) is maintained by a
quality control system. When a newly synthesized ER protein misfolds, it is ultimately …

Summary The Cdc48 ATPase and its cofactors Ufd1/Npl4 (UN) extract polyubiquitinated
proteins from membranes or macromolecular complexes, but how they perform these …

Advances over the past 25 years have revealed much about how the structural properties of
membranes and associated proteins are linked to the thermodynamics and kinetics of …
