  • 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.
  • Sequence similarities
    Belongs to the synaptotagmin family.
    Contains 2 C2 domains.
  • Domain
    The first C2 domain mediates Ca(2+)-dependent phospholipid binding.
    The second C2 domain mediates interaction with SV2A and STN2.
  • Cellular localization
    Cytoplasmic vesicle > secretory vesicle > synaptic vesicle membrane. Cytoplasmic vesicle > secretory vesicle > chromaffin granule membrane. Cytoplasm. Synaptic vesicles and chromaffin granules.

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 47 kDa
    Observed band size: 60 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 48 kDa, 50 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 30 seconds

    The predicted molecular weight of Synaptotagmin 1 is 47 kDa (SwissProt), however we expect to observe a banding pattern at 60 kDa. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.
