A Single Molecular Study Of The Regulation Of Snare-Mediated Membrane Fusion, Jaekyun Song
Graduate Theses and Dissertations
The presynaptic membrane fusion is mediated by a protein set called SNARE (Soluble NSF Attachment protein REceptor) proteins. SNARE proteins form a ternary SNARE-complex that comprises minimal machinery for membrane fusion; the complex consists of three SNARE proteins: Syntaxin 1, SNAP-25 and Vamp 2, also called Synaptobrevin 2. The SNARE complex is a four-helix coiled coil with four SNARE motifs; two come from SNARE-25 and one each from Syntaxin 1 and Vamp 2. It is believed that a regulatory protein Complexin binds tightly to the SNARE complex and stabilizes the complex, preventing it from driving toward fusion. However, the detailed ...
