Phosphorylated PKR contributes the induction of GRP94 under ER stress.

Abstract

Phosphorylated double-stranded RNA-dependent protein kinase (PKR) is thought to play an important role during ER stress induced cell death, but its molecular mechanism of action has not yet been clarified completely. To resolve this issue, we employed a PKR inhibitor together with ER stress inducers (tunicamycin, thapsigargin, and 2-deoxyglucose) and found… (More)
