Study results provide evidence that phosphatidylinositol 4,5-bisphosphate modulates the activity of essential signaling effectors in response to cold and that Pho85 is a central regulator of lipid homeostasis in yeast Saccharomyces cerevisiae. Its activity connects different lipid biosynthesis pathways to endow yeast cells with the optimal lipid profile to face with thermal stress.
Title: Pho85 and PI(4,5)P(2) regulate different lipid metabolic pathways in response to cold.
Pho85/CDK5 provides protection against hyperosmotic stress and acts before long-term adaptation provided by Hog1. This protection requires the vacuolar/endolysosomal signaling lipid PI3,5P2 We show that Pho85/CDK5 directly phosphorylates and positively regulates the PI3P-5 kinase Fab1/PIKfyve complex and provide evidence that this regulation is conserved in mammalian cells.
