Non-vesicular transport of ceramide from endoplasmic reticulum to Golgi membranes is essential for cellular lipid homeostasis. Protein kinase D (PKD) is a serine-threonine kinase that controls vesicle fission at Golgi membranes. Here we highlight the intimate connections between non-vesicular and vesicular transport at the level of the Golgi complex, and suggest that PKD and its substrate CERT, the ceramide transfer protein, play central roles in coordinating these processes by fine-tuning the local membrane lipid composition to maintain Golgi secretory function.
