  1. 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

  2. synaptic transmission can be regulated by Syt1 multimerization and that both C2 domains of Syt1 are uniquely required for modulating Ca(2 (show CA2 Proteins)+)-independent spontaneous fusion and Ca(2 (show CA2 Proteins)+)-dependent synchronous release.

  3. effect of APP (show APP Proteins) gene on synaptotagmin 1 mRNA level

  4. 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.

  5. 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 Proteins)+) binding with vesicle fusion

  6. Results suggest that the tandem C2 domains of Syt 1 play independent roles in neurotransmission.

  7. The C(2)B Ca(2+)-binding motif of synaptotagmin is required for synaptic transmission in vivo

  8. Synaptotagmins I and IV promote transmitter release independently of Ca(2 (show CA2 Proteins)+) binding in the C(2)A domain

  9. 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.

  10. These results indicate that synaptotagmin is the major Ca(2 (show CA2 Proteins)+) sensor for evoked release and functions to trigger synchronous fusion in response to Ca(2 (show CA2 Proteins)+), while suppressing asynchronous release.

Mouse (Murine) Synaptotagmin I (SYT1) interaction partners

  1. different structural states of syt (show SS18 Proteins) underlie the control of distinct forms of synaptic transmission.

  2. The interaction of Dvl1 (show DVL1 Proteins) with Syt-1, which is regulated by Wnts, modulates neurotransmitter release.

  3. Data (including data from studies in knockout mice) suggest that loss of both Syt1/Syt7 (show SYT7 Proteins) decreases capacity of readily-releasable pool (RRP (show RRBP1 Proteins)) of Ca2 (show CA2 Proteins)+ in synaptic vesicles without altering rate of priming into RRP (show RRBP1 Proteins); Syt1/Syt7 (show SYT7 Proteins) functions appear redundant.

  4. Syt-1 regulates Abeta (show APP Proteins) levels in mouse neurons. Knockdown of endogenous Syt-1 in mouse primary neurons led to a significant reduction in both Abeta40 and Abeta42 generation.

  5. Increased expression of Syt1 in neural stem cells is essential for neurogenesis progression.

  6. This study provides new insights in how the two opposite sides of the C2B domain of Synaptotagmin-1 participate in secretory vesicle fusion, and in more upstream steps, especially vesicle docking.

  7. atomic-resolution crystal structures of Ca(2 (show CA2 Proteins)+)- and Mg(2 (show MCOLN1 Proteins)+)-bound complexes between synaptotagmin-1 and the neuronal SNARE (show VTI1B Proteins) complex

  8. the Ca(2+) dependence of the interaction between PRIP-C2 and Syt1-C2A was attributed to Ca(2+) binding with Syt1-C2A, but not PRIP-C2, using a series of mutants prepared from both C2 domains.

  9. Tissue-specific splicing, posttranslational modification and the variation in expression might suggest a different requirement of SYT1 for the specific function in each organ.

  10. This study reveals fundamental details of how phosphorylation of Thr84 on SV2A (show SV2A Proteins) controls its interaction with synaptotagmin-1 and implicates SV2A (show SV2A Proteins) as a phospho-dependent chaperone

  1. One-Step reverse transcriptase real time PCR for the detection SYT (show SS18 Proteins)-SSX (show SSX2 Proteins) transcript is feasible as an aid in confirming the diagnosis of synovial sarcoma.

  2. membrane tethering by E-Syt1 (ER to PM) and by synaptotagmin (secretory vesicles to PM) undergo a similar regulation by plasma membrane lipids and cytosolic Ca(2 (show CA2 Proteins)+).

  3. A dominant negative de novo SYT1 missense variant(I368T)altered the kinetics of synaptic vesicle endocytosis and caused an early onset dyskinetic movement disorder, severe motor delay, and profound cognitive impairment.

  4. Data suggest that calcium-dependent phosphatidylinositol 4,5-diphosphate- (PI(4,5)P2-) binding proteins (such as SYT1, PRKCA (show PKCa Proteins) [protein kinase C alpha (show PKCa Proteins)], and ANXA2 (show ANXA2 Proteins) [annexin A2 (show ANXA2 Proteins)]) interactions with membrane microdomains are tightly regulated.

  8. synaptotagmin-1 is involved in a rapid vesicular Ca(2 (show CA2 Proteins)) sequestration through a Ca(2 (show CA2 Proteins))/H antiport

  9. PRIP inhibits regulated exocytosis through the interaction of its C2 domain with syntaxin 1 (show STX1A Proteins) and SNAP-25 (show SNAP25 Proteins), potentially competing with accessory proteins such as synaptotagmin I and by directly inhibiting trans-SNARE (show NAPA Proteins) complex formation

Protein Summary

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
