  ID: SYT1_HUMAN
DESCRIPTION: RecName: Full=Synaptotagmin-1; AltName: Full=Synaptotagmin I; Short=SytI; AltName: Full=p65;
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 Ca(2+)-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 Ca(2+)-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: Homotetramer (Probable). Interacts with SCAMP5, STON2, SV2A, SV2B, SV2C and RIMS1. Forms a complex with SV2B, syntaxin 1 and SNAP25 (By similarity).
INTERACTION: O00305-2:CACNB4; NbExp=2; IntAct=EBI-524909, EBI-714855; Q9Y6K9:IKBKG; NbExp=3; IntAct=EBI-524909, EBI-81279;
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.
DOMAIN: The first C2 domain mediates Ca(2+)-dependent phospholipid binding.
DOMAIN: The second C2 domain mediates interaction with SV2A and STN2 (By similarity).
SIMILARITY: Belongs to the synaptotagmin family.
SIMILARITY: Contains 2 C2 domains.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
