Label-free proteomics of immuno-purified SYP61-trans-Golgi Network compartment in control condition and upon sphingolipid acyl-chain length reduction by metazachlor.
Ontology highlight
ABSTRACT: 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.
