Endoplasmic reticulum-dependent redox reactions control endoplasmic reticulum-associated degradation and pathogen entry.
SIGNIFICANCE Protein misfolding within the endoplasmic reticulum (ER) is managed by an ER quality control system that retro-translocates aberrant proteins into the cytosol for proteasomal destruction. This process, known as ER-associated degradation, utilizes the action of ER redox enzymes to accommodate the disulfide-bonded nature of misfolded proteins. Strikingly, various pathogenic viruses a...
متن کاملTorsinA participates in endoplasmic reticulum-associated degradation
TorsinA is an AAA+ ATPase located within the lumen of the endoplasmic reticulum and nuclear envelope, with a mutant form causing early onset torsion dystonia (DYT1). Here we report a new function for torsinA in endoplasmic reticulum-associated degradation (ERAD). Retro-translocation and proteosomal degradation of a mutant cystic fibrosis transmembrane conductance regulator (CFTRΔF508) was inhib...
متن کاملSel1L is indispensable for mammalian endoplasmic reticulum-associated degradation, endoplasmic reticulum homeostasis, and survival.
Suppressor/Enhancer of Lin-12-like (Sel1L) is an adaptor protein for the E3 ligase hydroxymethylglutaryl reductase degradation protein 1 (Hrd1) involved in endoplasmic reticulum-associated degradation (ERAD). Sel1L's physiological importance in mammalian ERAD, however, remains to be established. Here, using the inducible Sel1L knockout mouse and cell models, we show that Sel1L is indispensable ...
متن کاملRoles of ubiquitin in endoplasmic reticulum-associated protein degradation (ERAD).
In the secretory pathway, quality control for the correct folding of proteins is largely occurring in the endoplasmic reticulum (ER), at the earliest possible stage and in an environment where early folding intermediates mix with terminally misfolded species. An elaborate cellular mechanism aims at dividing the former from the latter and promotes the selective transport of misfolded species bac...
متن کاملRegulation of Endoplasmic Reticulum-Associated Protein Degradation (ERAD) by Ubiquitin
Quality control of protein folding inside the endoplasmic reticulum (ER) includes chaperone-mediated assistance in folding and the selective targeting of terminally misfolded species to a pathway called ER-associated protein degradation, or simply ERAD. Once selected for ERAD, substrates will be transported (back) into the cytosol, a step called retrotranslocation. Although still ill defined, r...
