Syntaxin-binding protein

spinqualitylabelsall models Caption for this structure Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D Function Syntaxin-binding proteins (STXBP) are involved in the regulation of synaptic vesicle docking and fusion. STXBP1 participates in synaptic vesicle fusion via dual roles: as a docking/chaperone protein by binding Syntaxin-1 and as a fusion protein that binds SNARE complexes in a Syntaxin-1 N-peptide-dependent manner. STXBP2 binds SNARE proteins.
