Description
Participates in the regulation of synaptic vesicle docking and fusion through interaction with GTP-binding proteins (PubMed: 21689256). Essential for neurotransmission and binds syntaxin, a component of the synaptic vesicle fusion machinery probably in a 1:1 ratio. Can interact with syntaxins 1, 2, and 3 but not syntaxin 4. May play a role in determining the specificity of intracellular fusion reactions
