Syntaxin 1 is a small integral membrane protein that is abundantly expressed in neurons and neuroendocrine cells and thought to be implicated in the regulation of synaptic neurotransmitter release. Syntaxin 1 interacts with several other proteins important for synaptic function (SNAP 25, Munc 18). Syntaxin 1 is the main target of one of the Botulinum neurotoxins (BoNT/C1) which, however, cannot cleave the protein when complexed with its partner proteins in the fusion complex. Syntaxin 1 is an essential component of the neurotransmitter release machinery, and regulation of Syntaxin 1 expression levels is thought to contribute to the mechanism underlying learning and memory.
