An In Vitro Assay of Trans -SNARE Complex Formation During Yeast Vacuole Fusion Using Epitope Tag-Free SNAREs
2019
: SNARE complexes assembled between fusing membranes (in trans) are the core machinery driving lipid bilayer merger. Thus, an assay monitoring the formation of these trans-SNARE complexes is essential for SNARE-mediated membrane fusion studies. Homotypic yeast vacuole fusion is an important model system for such studies. Although several assays measuring trans-SNARE complex formation are available to study yeast vacuole fusion, most use SNAREs conjugated with epitope tags, which may affect the function of SNAREs or even the formation of trans-SNARE complexes. Here, I describe an assay for trans-SNARE complex formation during yeast vacuole fusion that does not require epitope-tagged SNAREs.
