AR15 Trigger Upgrades. 1  The trigger is one of the most crucial elements in achieving the highest level of accuracy from any firearm. Installation of a quality trigger will permit a light pull with little or no creep and overtravel.
The unfolded protein response (UPR) is a cellular stress response related to the endoplasmic reticulum (ER).It is a stress response that has been found to be conserved between all mammalian species, as well as yeast and worm organisms.This article focuses on the mammalian response. The UPR is activated in response to an accumulation of unfolded or misfolded proteins in the lumen of the endoplasmic reticulum.ranslation Attenuation and Cell Cycle Arrest by the PERK Receptor This occurs within minutes to hours of UPR activation to prevent further translational loading of the ER. PERK (protein kinase RNA-like endoplasmic reticulum kinase) activates itself by oligomerization and autophosphorylation of the free luminal domain.
