The synaptotagmins are integral membrane proteins of synaptic vesicles thought to serve as Ca(2+) sensors in the process of vesicular trafficking and exocytosis. Calcium binding to synaptotagmin I participates in triggering neurotransmitter release at the synapse Gustavsson N, et al. Proc Natl Acad Sci U S A. 2008 Mar 11; 105(10):3992-7. Cnops L, et al.

Host
Rabbit
Immunogen
Peptide sequence around phosphorylation site of serine 309 (G-L-S(p)-D-P) derived from Human Synaptotagmin 1.
Involvement In Disease
A SYT1 rare mutation has been found in a child with a severe neuro-developmental disorder. The individual harboring this variant shows early onset dyskinetic movement disorder, severe motor delay and profound cognitive impairment, suggesting that SYT1 may play a role in the pathogenesis of this neuro-developmental disorder.

Species
Homo Sapiens (Human)
Specificity
The antibody detects endogenous level of Synaptotagmin 1 only when phosphorylated at serine 309.
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

Purification
Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy usi
