Summary: The endoplasmic reticulum (ER) stress response. also known as the unfolded protein response (UPR). is a complex cellular response to ER protein misfolding that involves transcriptional regulatory branches and a PERK-mediated translational regulatory branch. Here we revealed that amino acid biosynthesis regulation is coupled to protein synthesis demands during ER stress. https://parisnaturalfoodes.shop/product-category/brow-pencil-blonde-1605/
