ER-associated protein degradation initiates by retrotranslocation from the ER quality control compartment

Chaitanya Patel, Navit Ogen‐Shtern, Haddas Saad…·Gerardo Zelmar Lederkremer

The paper detects early ERAD initiation events using a BAP-BirA system and shows substrates engage retrotranslocation machinery while remaining membrane-associated.

Oligosaccharyltransferase is involved in targeting to ER-associated degradation

Marina Shenkman, Navit Ogen‐Shtern, Chaitanya Patel…·Gerardo Zelmar Lederkremer

The paper identifies oligosaccharyltransferase (OST) subunits as key interactors in ER-associated degradation (ERAD), suggesting a role in late stages of quality control beyond N-glycosylation.
