Terminally misfolded proteins, recognized by chaperones on the endoplasmic reticulum (ER), are transported to depots for ubiquitinylation and proteasomal degradation by the ER-associated protein degradation (ERAD) pathway. Eeyarestatin 1 is an inhibitor of the ERAD pathway, blocking the degradation of misfolded proteins at a dose of 8 µM.{15691} It associates with the p97-associated deubiquitinylating complex in cells, preventing deubiquitinylation of substrates by ataxin-3.{27313,27314} Eeyarestatin 1, at 4 µM, interferes with both retrograde and anterograde trafficking of proteins, including certain toxins, and potentially, viruses.{27315}
