Summary
Eeyarestatin I, a potent endoplasmic reticulum-associated protein degradation (ERAD) inhibitor, is a potent protein translocation inhibitor. Eeyarestatin I inhibits Sec61 translocon. Eeyarestatin I targets the p97-associated deubiquitinating process (PAD) and inhibits atx3-dependent deubiquitination. Eeyarestatin I interferes at a step prior to proteasomal degradation. Eeyarestatin I induces cell death via the proapoptotic protein NOXA and has anticancer effects [1] [2] [3] [4] [5] .
In Vitro
Eeyarestatin I (2.5-40 μM; 48 hours; A549 and H358 cells) treatment causes a dose-dependent cell death of both A549 and H358 cells
[1]
.
Eeyarestatin I (2.5-40 μM; 48 hours; A549 and H358 cells) treatment increases endoplasmic reticulum (ER) stress markers including Bip and CHOP as low as 20 μM. Eeyarestatin I treatment shows a dose dependent ubiquitination of key proteins including PERK and IRE1α
[1]
.
Eeyarestatin I (20 μM; 48 hours; A549 and H358 cells) treatment induces cell migration and cell invasion
[1]
.
Eeyarestatin 1 prevents the transfer of nascent proteins from the membrane-targeting complex to the ER translocation machinery, most probably by inactivating the Sec61 complex
[2]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
