Protein Structure
UniProt Annotation
Function May be involved in Ca(2+)-dependent exocytosis of secretory vesicles through Ca(2+) and phospholipid binding to the C2 domain or may serve as Ca(2+) sensors in the process of vesicular trafficking and exocytosis.
Subcellular Localization Cytoplasmic vesicle, secretory vesicle, synaptic vesicle membrane; Single-pass membrane protein.
Disease Associations
Tissue Specificity Expressed in brain. Within brain, expression is highest in hippocampus, with substantial levels also detected in amygdala and thalamus.
