'''Syntaxin-binding protein'''s (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<ref>PMID:21193638</ref>. '''STXBP2''' binds SNARE proteins. | '''Syntaxin-binding protein'''s (STXBP) are involved in the regulation of synaptic vesicle docking and fusion.
