Syntaxin 1 functions by forming a complex with other SNARE proteins, such as SNAP-25 and VAMP (synaptobrevin), to facilitate the merging of synaptic vesicles with the plasma membrane. This process, known as vesicle fusion, is essential for the release of neurotransmitters into the synaptic cleft. The interaction between Syntaxin 1 and other SNARE proteins is highly specific and regulated, ensuring the precise timing and location of neurotransmitter release.
