Animal cells coordinate lipid homeostasis by end-product feedback regulation of transcription. The control occurs through the proteolytic release of transcriptionally active sterol regulatory element binding proteins (SREBPs) from intracellular membranes. This feedback system has unexpected features that are found in all cells. Here, we consider recently discovered components of the regulatory machinery that govern SREBP processing, as well as studies in Drosophila that indicate an ancient role for the SREBP pathway in integrating membrane composition and lipid biosynthesis.
