Requirement of the p38 mitogen-activated protein kinase signalling pathway for the induction of the 78 kDa glucose-regulated protein/immunoglobulin heavy-chain binding protein by azetidine stress: activating transcription factor 6 as a target for stress-induced phosphorylation.

Abstract excerpt

Malfolded protein formation and perturbance of calcium homoeostasis results in the induction of the endoplasmic reticulum (ER) chaperone protein, namely the 78 kDa glucose-regulated protein (GRP78)/immunoglobulin heavy-chain binding protein. Various ER stress inducers can activate grp78, but signal transduction mechanisms are not well understood. We report in the present study that the induction of endogenous...
