Zusammenfassung

Englisch

In this work, I have thoroughly characterized a novel complex containing syntaxin1a (1-288), SNAP25a and Munc18-1 and established it as an efficient acceptor complex for synaptobrevin-binding, using several biochemical and biophysical techniques. The use of all full-length proteins provide tremendous strength to the study, giving it a ‘near-native’ scenario for the behaviors of the proteins being discussed. In addition to understanding the functional importance of this complex, I also attained its structural overview using chemical crosslinking assays. And, finally, by testing the resistance of this complex to disassembly by NSF-αSNAP, I could establish that the syntaxin1a/SNAP25a/Munc18-1 complex can allow SNARE-assembly to proceed in an NSF-αSNAP-resistant manner.
Keywords: SNAREs, Munc18, synaptic vesicle exocytosis
