Function

Potentially involved in docking of synaptic vesicles at presynaptic active zones. May play a critical role in neurotransmitter exocytosis. May mediate Ca(2+)-regulation of exocytosis acrosomal reaction in sperm. {ECO:0000269PubMed:15774481}.

Subcellular Localization

Cytoplasmic vesicle, secretory vesicle, synaptic vesicle membrane {ECO:0000269PubMed:18760330}; Single- pass type IV membrane protein {ECO:0000269PubMed:18760330}. Cell junction, synapse, synaptosome {ECO:0000269PubMed:18760330}.
