General annotation (Comments)

Function

May have a regulatory role in the membrane interactions during trafficking of synaptic vesicles at the active zone of the synapse. It binds acidic phospholipids with a specificity that requires the presence of both an acidic head group and a diacyl backbone. A Ca2+-dependent interaction between synaptotagmin and putative receptors for activated protein kinase C has also been reported. It can bind to at least three additional proteins in a Ca2+-independent manner; these are neurexins, syntaxin and AP2.

Cofactor

Binds 3 calcium ions per subunit. The ions are bound to the C2 domains By similarity.

Subunit structure

Homotetramer Probable. Interacts with SCAMP5, STN2, SV2A, SV2B, SV2C and RIMS1 By similarity. Forms a complex with SV2B, syntaxin 1 and SNAP25.

Subcellular location

Cytoplasmic vesiclesecretory vesiclesynaptic vesicle membrane; Single-pass membrane protein. Cytoplasmic vesiclesecretory vesiclechromaffin granule membrane; Single-pass membrane protein. Cytoplasm. Note: Synaptic vesicles and chromaffin granules.

Domain

The first C2 domain mediates Ca2+-dependent phospholipid binding.

The second C2 domain mediates interaction with SV2A and STN2 By similarity.

Sequence similarities

Belongs to the synaptotagmin family.

Contains 2 C2 domains.
