Unfolded Protein Response Review. In response to stress eg accumulation of misfolded proteins the ER triggers the unfolded protein response UPR a complex and conserved signalling pathway that is mediated by three ER transmembrane sensor proteins. Mediated by the unfolded protein response UPR a signal transduction pathway that senses the fidelity of protein folding in the ER lumen. A diverse array of cellular stresses can lead to dysfunction of the ER and ultimately to an imbalance between protein-folding capacity and protein-folding load. Recent evidence implicates the participation of adaptive responses to stress within the endoplasmic reticulum ER in the disease process via a pathway known as the unfolded protein response UPR.
