RL Submitted (NOV-2023) to UniProtKB.
CC -!- FUNCTION: May have a regulatory role in the membrane interactions
CC during trafficking of synaptic vesicles at the active zone of the
CC synapse. It binds acidic phospholipids with a specificity that requires
CC the presence of both an acidic head group and a diacyl backbone.
CC {ECO:0000256|RuleBase:RU367154}.
CC -!- COFACTOR:
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108;
CC Evidence={ECO:0000256|RuleBase:RU367154};
CC Note=Binds 3 Ca(2+) ions per subunit. The ions are bound to the C2
CC domains. {ECO:0000256|RuleBase:RU367154};
CC -!- SUBCELLULAR LOCATION: Cytoplasmic vesicle, secretory vesicle, synaptic
CC vesicle membrane {ECO:0000256|RuleBase:RU367154}; Single-pass membrane
CC protein {ECO:0000256|RuleBase:RU367154}.
CC -!- SIMILARITY: Belongs to the synaptotagmin family.
CC {ECO:0000256|ARBA:ARBA00006996, ECO:0000256|RuleBase:RU367154}.
