Shinoda, Ahmed, Ramachandran, Bharat, Brockelt, Altas, Dean: BDNF enhances spontaneous and activity-dependent neurotransmitter release at excitatory terminals but not at inhibitory terminals in hippocampal neurons. in Frontiers in synaptic neuroscience 2014
The present study replicates previously suggested association of the SYT1-rs2251214 SNP with ADHD in adults.
The MD simulations revealed that all peptides induced significant Syt1 rigidity by binding in the cleft of the C2A-C2B interface. The consequence of this binding event is the suppression of the protein motion associated with conformational change of Syt1 from the closed form to the open form.
Although both otoferlin (show OTOF Antibodies) and synaptotagmin bind membrane fusion SNARE (show NAPA Antibodies) proteins, only otoferlin (show OTOF Antibodies) interacts with the L-type calcium channel Cav1.3 (show CACNA1D Antibodies).
Circular oligomerization is an intrinsic property of SYT1.
that reduction in the synaptotagmin 1 level and presenilin 1 (show PSEN1 Antibodies)-synaptotagmin 1 interactions in AD brain may present molecular underpinning of the pathogenic presenilin 1 (show PSEN1 Antibodies) conformation
findings show extended Synaptotagmi1 (E-Syt1 (show ESYT1 Antibodies)), along with related E-Syt3 (show ESYT3 Antibodies), negatively modulates viral release into the extracellular milieu, cell-to-cell viral spread and viral entry, processes that implicate membrane fusion events; , these E-Syt (show SS18 Antibodies) proteins impacted formation of virus-induced syncytia; findings hint at the modulation of the viral fusion machinery by the E-Syt (show SS18 Antibodies) family of proteins
Using electron microscopy combined with targeted mutations, the authors show that under physiologically relevant conditions, both the Syt1 ring assembly and its rapid disruption by Ca(2+) involve the well-established functional surfaces on the C2B domain that are important for synaptic transmission.
This study found that the CSF (show CSF2 Antibodies) levels of synaptotagmin-1 were consistently elevated in patients with dementia due to Alzheimer's disease.
SYT (show SS18 Antibodies)-SSX (show SSX2 Antibodies) fusion is associated with synovial sarcoma.
the extended synaptotagmins (E-Syts), endoplasmic reticulum (ER) proteins that function as PtdIns(4,5)P2- and Ca(2 (show CA2 Antibodies)+)-regulated tethers to the Pplasma membrane.
This study uncovered essential residues within Synaptotagmin that suggest a structural basis for several activities required for fusion, including a C2B domain surface implicated in SNARE (show NAPA Antibodies) complex interaction that is required for rapid synchronization and Ca(2 (show CA2 Antibodies)+) cooperativity of vesicle release.
tethering of Syt1 to synaptic vesicles in vivo is a prerequisite for its role in facilitating fast synchronous synaptic vesicle release and suppressing asynchronous and spontaneous fusion
synaptic transmission can be regulated by Syt1 multimerization and that both C2 domains of Syt1 are uniquely required for modulating Ca(2 (show CA2 Antibodies)+)-independent spontaneous fusion and Ca(2 (show CA2 Antibodies)+)-dependent synchronous release.
effect of APP (show APP Antibodies) gene on synaptotagmin 1 mRNA level
The major function of Ca2+ binding to synaptotagmin's C2A domain is to neutralize the negative charge of the pocket, thereby unleashing the fusion-stimulating activity of synaptotagmin.
this study provided direct support for the hypothesis that plasma membrane penetration, specifically by the C(2)B domain of synaptotagmin, is the critical effector interaction for coupling Ca(2 (show CA2 Antibodies)+) binding with vesicle fusion
Results suggest that the tandem C2 domains of Syt 1 play independent roles in neurotransmission.
The C(2)B Ca(2+)-binding motif of synaptotagmin is required for synaptic transmission in vivo
Synaptotagmins I and IV promote transmitter release independently of Ca(2 (show CA2 Antibodies)+) binding in the C(2)A domain
Data show that synaptotagmin I is required for a post-docking step during vesicle fusion but does not function to stabilize the docked vesicle state.
Study showed postsynaptic localization of synaptotagmin 1, at concentrations moderately lower than, but comparable to presynaptic concentrations. It is present in significant concentrations at the postsynaptic density, pointing to the likelihood of insertion of glutamate (show GRIN1 Antibodies) receptors directly into the synaptic plasma membrane. Synaptotagmin 1 is reduced in postsynaptic spines after eight weeks of kainite-induced epilepsy.
Authors propose that the strong reduction of Syt2 (show SYT2 Antibodies) and SV2B (show SV2B Antibodies) are key factors of the functional synaptic alteration and that the physiological downregulation of Syt1 plays a determinant role in muscle vulnerability in SMA (show SMN1 Antibodies).
The function of synaptotagmin-1 (syt-1):soluble NSF attachment protein (show NAPG Antibodies) receptor (SNARE (show VTI1B Antibodies)) interactions during neurotransmission remains unclear.
we identify Syt2 (show SYT2 Antibodies) as a functionally important Ca(2 (show CA2 Antibodies)+) sensor at fast-releasing inhibitory synapses, and show that Syt1 and Syt2 (show SYT2 Antibodies) can redundantly control transmitter release at specific brain synapses
results suggest that postsynaptic Syt1 and Syt7 (show SYT7 Antibodies) act as redundant Ca(2 (show CA2 Antibodies)+)-sensors for Ca(2 (show CA2 Antibodies)+)-dependent exocytosis of AMPA (show GRIA3 Antibodies) receptors during long-term potentiation, and thereby delineate a simple mechanism for the recruitment of AMPA (show GRIA3 Antibodies) receptors that mediates LTP (show SCP2 Antibodies)
demonstrates a developmental Syt1-Syt2 (show SYT2 Antibodies) isoform switch at an identified synapse, a mechanism that could fine-tune the speed, reliability, and plasticity of transmitter release at fast releasing CNS synapses.
the combined inactivation of all 3 E-Syt (show SS18 Antibodies) genes has no effect on mouse viability or fertility.
We conclude that synaptotagmin-1 phosphorylation is an essential step in PKC (show PKC Antibodies)-dependent potentiation of synaptic transmission, acting downstream of the two other essential DAG/PKC (show PKC Antibodies) substrates, Munc13-1 (show UNC13A Antibodies) and Munc18-1 (show STXBP1 Antibodies).
data show that hepatic Syt1 expression is influenced by diet and hormonal milieu
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-1 participates in triggering neurotransmitter release at the synapse (Fernandez-Chacon et al., 2001
