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://xiuvonvzd3ug2.celticwiki.com/1456136/sins_ar_an_efficient_smart_indoor_navigation_system_based_on_augmented_reality
