title: ER quality control: a function for sugars in the cytosol.
abstract: Misfolded glycoproteins in the endoplasmic reticulum of a eukaryotic cell are exported to the cytosol, where they are proteolytically degraded by the ubiquitin-proteasome system. A recent study has identified a novel E3 ubiquitin ligase that recognises target glycoproteins via their sugar moieties.
