abstract：:An increasing body of data links endoplasmic reticulum (ER) function to autophagy. Not surprisingly, then, some aberrant proteins in the ER can be destroyed either via ER associated degradation (ERAD), which is proteasome-mediated, or via autophagy. One such substrate is the "Z" variant of the alpha-1 protease inhibit...
