The lipid content of the plasma membrane is dynamically regulated to maintain cellular homeostasis, but the molecular links between membrane stress and sphingolipid synthesis have remained elusive. Walther, Loewith and colleagues report that membrane stretching causes redistribution of Slm proteins, which then promote sphingolipid synthesis through activation of the TORC2–Ypk signalling pathway.
