'''Syntaxin''' (Stx) are membrane-integrated proteins that are instrumental in exocytosis of vesicles. Stx-1 is essential for the formation of the SNARE complex involved in the fusion machinery in the brain. Stx-1 forms a 4-helical bundle complex with proteins SNAP-25 and VAMP2 which drives fusion of vesicles with the plasma membrane<ref>PMID:26903802</ref>. The coiled-coil bundle structure is formed by the interactions of the complex SNARE motifs<ref>PMID:24218570</ref>. | '''Syntaxin''' (Stx) are membrane-integrated proteins that are instrumental in exocytosis of vesicles.
