GO:1904378:   maintenance of unfolded protein involved in ERAD pathway
Maintaining an endoplasmic reticulum (ER) protein in an unfolded, soluble state that contributes to its degradation by the cytoplasmic proteasome. Maintaining ER-resident proteins in an unfolded yet soluble state condition after their retro-translocation favors their turnover by the cytosolic proteasome.
