Calcium sensor that participates in triggering neurotransmitter release at the synapse. 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. Plays a role in dendrite formation by melanocytes. ; (Microbial infection) Receptor for C.botulinum neurotoxin type B (BoNT/B, botB) ; interaction is improved in the presence of gangliosides. BoNT/B toxin binds to the membrane proximal vesicular domain of Syt1 (residues 32-51) . ; (Microbial infection) Receptor for C.botulinum neurotoxin type G (BoNT/G, botG) ; unlike the case with BoNT/B, interaction is not improved in the presence of gangliosides. BoNT/G toxin binds to the vesicular domain of Syt1 (residues 32-53) .

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
