Merck, E1286-10MG, Eeyarestatin I

Biochem/physiol Actions
Eeyarestatin I is a potent inhibitor of endoplasmic reticulum associated protein degradation (ERAD). Specifically targets the p97-associated deubiquinating process (PAD) and inhibits ataxin-3 (atx3)-dependent deubiquitination.
Eeyarestatin I is a potent inhibitor of endoplasmic reticulum associated protein degradation (ERAD). Specifically targets the p97-associated deubiquinating process (PAD) and inhibits ataxin-3 (atx3)-dependent deubiquitination. Also inhibits Sec61-mediated protein translocation at the ER. Displays cytotoxic activity preferentially against cancer cells; induces cell death via the proapoptotic protein NOXA.
Eeyarestatin I or Eer1 promotes transcriptional activation of the pro-apoptotic protein NOXA by inducing activation of the NOXA transcription factors ATF3 and ATF4 and by inhibiting the degradation of histone H2A by blocking its ubiquitination.
