Entry Information
Comments
| Comment Type | Description |
|---|---|
| Cofactor | Name=Ca(2+); Xref=ChEBI:CHEBI:29108; Evidence= ; Note=Binds 3 Ca(2+) ions per subunit. The ions are bound to the C2 domains. ; |
| Domain | The first C2 domain mediates Ca(2+)-dependent phospholipid binding. |
| Domain | The second C2 domain mediates interaction with Stonin 2 |
| 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. |
| Interaction | P10844:botB (xeno); NbExp=3; IntAct=EBI-458017, EBI-7661991; Q9H4A3:WNK1 (xeno); NbExp=2; IntAct=EBI-458017, EBI-457907; Q9JIH7:Wnk1; NbExp=9; IntAct=EBI-458017, EBI-457953; |
| Similarity | Belongs to the synaptotagmin family |
| Similarity | Contains 2 C2 domains. {ECO:0000255|PROSITE- ProRule:PRU00041}. |
| Subcellular Location | Cytoplasmic vesicle, secretory vesicle, synaptic vesicle membrane; Single-pass membrane protein. Cytoplasmic vesicle, secretory vesicle, chromaffin granule membrane; Single-pass membrane protein. Cytoplasm. Note=Synaptic vesicles and chromaffin granules. |
| Subunit | Homotetramer (Probable). Interacts with SCAMP5 and stonin 2 (By similarity) |
| Tissue Specificity | Predominantly expressed in phylogenetically older brain regions such as the spinal cord, brain stem and cerebellum. |
