Protein Structure
UniProt Annotation
Function Calcium sensor which most probably regulates fusion of vesicles with membranes. Binds calcium and phospholipids. May be involved in calcium dependent neurotransmitter release through the interaction with UNC13A. May be involved in calcium-dependent spontaneous release of neurotransmitter in absence of action potentials in neuronal cells. Regulates Ca(2+)-dependent secretory lysosome exocytosis in mast cells. {ECO:0000269PubMed:18354201, ECO:0000269PubMed:9736751, ECO:0000269PubMed:9804756}.
Subcellular Localization Lysosome {ECO:0000250}. Cytoplasmic vesicle, secretory vesicle, synaptic vesicle membrane {ECO:0000305}; Peripheral membrane protein {ECO:0000305}. Cell junction, synapse, synaptosome. Note=Colocalizes to synaptic vesicles.
Disease Associations
Tissue Specificity Predominantly expressed in brain. Also expressed in testis. {ECO:0000269PubMed:7826360, ECO:0000269PubMed:8554557}.
