The Dynamin-Like Protein Vps1 Stimulates Endosome-To-Golgi Fusion In Vitro, Jared Christopher Smothers
MSU Graduate Theses
Intracellular membrane fusion events can be reconstituted by exploiting isolated organelles from cellular hosts or artificial membranes made of purified phospholipid components. Artificial construction of membranes provides two significant advantages. First, cellular isolation of the endosome-derived vesicles and TGN (trans-Golgi Network) compartments needed for the fusion assay would be extremely challenging. Second, reconstituting the membranes provides the added benefit of controlling size and lipid compositions to functionally mimic the individual membrane architectures and introduce only the purified proteins that are under investigation. For these reasons, I have developed the first simultaneous lipid and content mixing fusion assays that measures the …
