|Reactivity||Human, Mouse, Rat|
|Calculated MW||47399 Da|
|Positive Control||Rat kidney tissue lysate|
|Application & Usage||The antibody can be used in Western Blot analysis (1-4 µg/ml). However, the optimal concentrations should be determined individually. Blocking peptide is available separately.|
|Other Names||Synaptotagmin-1, Synaptotagmin I, SytI, p65, Syt1|
|Formulation||100 µg (0.5 mg/ml) affinity purified rabbit anti- Synaptotagmin polyclonal antibody in phosphate buffered saline (PBS), pH 7.2, containing 30% glycerol, 0.5% BSA, 5 mM EDTA and 0.01% thimerosal.|
|Handling||The antibody solution should be gently mixed before use.|
|Reconstitution & Storage||-20 °C|
|Precautions||Synaptotagmin Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|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. Plays a role in dendrite formation by melanocytes.|
|Cellular Location||Cytoplasmic vesicle, secretory vesicle membrane; Single-pass membrane protein. 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|
|Tissue Location||Predominantly expressed in rostral, phylogenetically younger brain regions, and in some endocrine tissues|

The synaptotagmins are integral membrane proteins of synaptic vesicles tho µght to serve as Ca (2+) sensors in the process of vesicular trafficking and exocytosis. Calcium binding to synaptotagmin participates in triggering neurotransmitter release at the synapse. The first C2 domain mediates Ca(2+)-dependent phospholipid binding. The second C2 domain mediates interaction with Stonin 2. Synaptotagmin 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.
