WebbAs extracellular proteins with danger signals are non-self-proteins, these proteins are recognized by the endoplasmic reticulum (ER)-resident molecular chaperones in the non-classical endosome. Recognition by the ER-resident molecular chaperones accelerates ER-associated degradation (ERAD)-dependent processing of exogenous proteins and … Webb2 dec. 2024 · Chaperones must recognize diverse toxic clients of di erent orders (soluble proteins, biomolecular condensates, organized protein aggregates). It is therefore critical to understand the basis of the selective chaperone recognition to discern the mechanisms of action of chaperones in protein conformational diseases.
