Updated project metadata. The trans-Golgi Network (TGN) in plants is a main sorting hub for proteins and lipids. The lipid composition at the TGN is instrumental to the polar sorting of the auxin efflux carrier PIN2 from TGN to the apical membrane. Here, we immuno-purified the full and intact TGN using the TGN-resident syntaxin SYP61 to identify and quantify TGN-proteins which abundance at TGN is dependent on the acyl-chain length of very-long chain fatty acids-containing lipids such as sphingolipids.
