Phosphatidylinositol-4-phosphate (PI(4)P) is an important regulator of Golgi function. Metabolic regulation of Golgi PI(4)P requires the lipid phosphatase Sac1 that translocates between endoplasmic reticulum (ER) and Golgi membranes. Localization of Sac1 responds to changes in glucose levels, yet the upstream signaling pathways that regulate Sac1 traffic are unknown. Here, we report that mitogen-activated protein kinase (MAPK) Hog1 transmits glucose signals to the Golgi and regulates localizatio ...[more]
