Protein Structure
UniProt Annotation
Function Positively regulates a late step in synaptic vesicle exocytosis. Organizes the SNAREs into a cross-linked zigzag topology that, when interposed between the vesicle and plasma membranes, is incompatible with fusion, thereby preventing SNAREs from releasing neurotransmitters until an action potential arrives at the synapse. Also involved in glucose-induced secretion of insulin by pancreatic beta-cells. Essential for motor behavior. {ECO:0000269PubMed:15126625, ECO:0000269PubMed:16000319}.
Subcellular Localization Cytoplasm, cytosol {ECO:0000269PubMed:15126625, ECO:0000269PubMed:7635198}. Note=Enriched at synaptic-releasing sites in mature neurons.
Disease Associations
Tissue Specificity Nervous system, and pancreatic islet cells. Present in many brain regions, including hippocampus and cerebellum. In the retina, present at conventional amacrine cell synapses (at protein level). {ECO:0000269PubMed:15126625, ECO:0000269PubMed:15911881, ECO:0000269PubMed:7635198}.
