Arabidopsis endomembrane enrichments: Affinity enrichment of RABF1/ARA6-RFP


ABSTRACT: Our aim was to dissect subcellular trafficking routes by enriching for partially overlapping subpopulations of endosomal proteomes associated with endomembrane markers. We selected RABD2a/ARA5, RABF2b/ARA7, RABF1/ARA6, and RABG3f as markers for combinations of the Golgi, trans-Golgi Network (TGN), Early Endosomes (EE), secretory vesicles, Late Endosomes (LE), Multivesicular Bodies (MVB) compartments and tonoplast. As comparisons we used Golgi transport 1 (GOT1), which localises to the Golgi, Clathrin Light Chain 2 (CLC2) labelling Clathrin-coated vesicles and pits and the Vesicle Associated Membrane Protein 711 (VAMP711) present at the tonoplast. We developed an easy-to-use method by refining published protocols based on affinity purification of fluorescent fusion constructs to these seven subcellular marker proteins in Arabidopsis thaliana seedlings.

The cell's endomembranes comprise an intricate, highly dynamic and well-organized system. In plants, the proteins that regulate function of the various endomembrane compartments and their cargo remain largely unknown. Our aim was to dissect subcellular trafficking routes by enriching for partially overlapping subpopulations of endosomal proteomes associated with endomembrane markers. We selected RABD2a/ARA5, RABF2b/ARA7, RABF1/ARA6, and RABG3f as markers for combinations of the Golgi, trans-Golg  ...[more]
