CtBP1-S/BARS is required for fission of endomembrane compartments including the Golgi. Here the authors show that CtBP1-S/BARS activates a trans-Golgi lysophosphatidic acid acyltransferase that catalyses the production of phosphatidic acid and is required for fission of the post-Golgi carrier membrane.
