An Evolutionarily Conserved Ypk1/SGK1 Kinase Pathway Regulates the Unfolded Protein Response by Modulating the Ire1 Protein Abundance
The unfolded protein response (UPR) is a cellular mechanism that maintains protein homeostasis (proteostasis) under conditions of endoplasmic reticulum (ER) stress. The dual kinase/RNase Ire1 is a conserved regulator of the UPR, mediating the unconventional cytosolic splicing of HAC1 mRNA in yeast and XBP1 mRNA in huma...
