Abstract
Intracellular organelles have specific lipid and protein compositions. Although great progress has been made concerning the mechanisms that govern the transport of proteins between organelles, little information is available about the mechanisms of inter-organellar lipid transport. New work identifies a protein that specifically transports ceramide, a precursor of sphingolipid synthesis, between intracellular organelles.
