Malonyl-CoA links lipid metabolism to nutrient signalling by directly inhibiting mTORC1

Cells use various metabolic pathways to synthesize the building blocks for growth and proliferation. To ensure balanced growth, these biosynthetic processes must be tightly coordinated. We describe a molecular machinery that senses the cellular capacity to make lipids to regulate other biosynthetic processes — such as protein synthesis — accordingly.
