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.
