<p> Syntaxins A and B are nervous system-specific proteins implicated in the docking of synaptic vesicles with the presynaptic plasma membrane. Syntaxins are a family of receptors for intracellular transport vesicles. Each target membrane may be identified by a specific member of the syntaxin family [<cite idref="PUB00000897"/>].Members of the syntaxin family [<cite idref="PUB00005397"/>, <cite idref="PUB00000891"/>] have a size ranging from30 Kd to 40 Kd; a C-terminal extremity which is highly hydrophobic and anchors the protein on the cytoplasmic surface of cellular membranes; a central, wellconserved region, which seems to be in a coiled-coil conformation.</p> Syntaxin, N-terminal
