Abstract

Proteins that fail to fold correctly in the endoplasmic reticulum (ER) are retrotranslocated back into the cytosol where they become ubiquitinated and are eventually degraded by the proteasome. This process is called ER-associated protein degradation (ERAD). Recent research revealed that the ER-membrane protein Hrd1, an E3 ubiquitin ligase, forms a minimal system to translocate misfolded proteins across the membrane of the ER.
