Structural Organization of the Synaptic Exocytosis Core Complex

Abstract

Syntaxin, vesicle-associated membrane protein (VAMP), and synaptosome-associated protein of 25 kDa (SNAP-25) form a ternary "core complex" central to the process of synaptic vesicle docking and fusion. Several lines of evidence support the hypothesis that the proteins assemble in a coiled-coil structure, but the alignment of alpha helices in this coil and the overall conformation of the coil are unknown. We employ the technique of fluorescence resonance energy transfer (FRET) to investigate the alignment between syntaxin and VAMP. With the acceptor probe coupled to the amino-terminal end of the VAMP coiled-coil domain, the donor probe fluorescence is quenched to a greater extent when it is on the amino-terminal end of the syntaxin H3 domain than when it is on the carboxy-terminal end. The data indicate that syntaxin and VAMP bind primarily in a parallel arrangement and suggest a coiled-coil structure that is bent rather than fully extended. We propose a model in which binding of SNAP receptor (SNARE) protein coiled-coil domains helps drive vesicle fusion.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
