THREE DIMENSIONAL STRUCTURE OF THE N-TERMINAL DOMAIN OF SYNTAXIN 1ATHREE DIMENSIONAL STRUCTURE OF THE N-TERMINAL DOMAIN OF SYNTAXIN 1A
Structural highlights
Function[STX1A_RAT] Potentially involved in docking of synaptic vesicles at presynaptic active zones. May play a critical role in neurotransmitter exocytosis. May mediate Ca(2+)-regulation of exocytosis acrosomal reaction in sperm. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedSyntaxin 1A plays a central role in neurotransmitter release through multiple protein-protein interactions. We have used NMR spectroscopy to identify an autonomously folded N-terminal domain in syntaxin 1A and to elucidate its three-dimensional structure. This 120-residue N-terminal domain is conserved in plasma membrane syntaxins but not in other syntaxins, indicating a specific role in exocytosis. The domain contains three long alpha helices that form an up-and-down bundle with a left-handed twist. A striking residue conservation is observed throughout a long groove that is likely to provide a specific surface for protein-protein interactions. A highly acidic region binds to the C2A domain of synaptotagmin I in a Ca2+-dependent interaction that may serve as an electrostatic switch in neurotransmitter release. Three-dimensional structure of an evolutionarily conserved N-terminal domain of syntaxin 1A.,Fernandez I, Ubach J, Dulubova I, Zhang X, Sudhof TC, Rizo J Cell. 1998 Sep 18;94(6):841-9.
