13. One-Step reverse transcriptase real time PCR for the detection SYT-SSX transcript is feasible as an aid in confirming the diagnosis of synovial sarcoma. PMID: 27126659
14. 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+). PMID: 26202220
15. 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. PMID: 25705886
16. Data suggest that calcium-dependent phosphatidylinositol 4,5-diphosphate- (PI(4,5)P2-) binding proteins (such as SYT1, PRKCA [protein kinase C alpha], and ANXA2 [annexin A2]) interactions with membrane microdomains are tightly regulated. [REVIEW] PMID: 25233429

19. Structural insights into the Ca2+ and PI(4,5)P2 binding modes of the C2 domains of rabphilin 3A and synaptotagmin 1. PMID: 24302762
20. synaptotagmin-1 is involved in a rapid vesicular Ca(2) sequestration through a Ca(2)/H antiport PMID: 23607712
21. PRIP inhibits regulated exocytosis through the interaction of its C2 domain with syntaxin 1 and SNAP-25, potentially competing with accessory proteins such as synaptotagmin I and by directly inhibiting trans-SNARE complex formation PMID: 23341457
22. Characterization of negative coupling interaction between the C2 domains of Syt I. PMID: 23071627
23. The mechanistic basis for C2A domain of synaptotagmin I's response to Ca(2+) and cellular function stems from marginal stability and ligand-induced redistributions of protein conformers. PMID: 22853901
24. The membrane dissociation of SYT7 C2A domain but not SYT1 C2A domain is slowed by Na(2)SO(4) and trehalose, solutes that enhance the hydrophobic effect. PMID: 22966849
25. Together with synaptotagmin 1, complexin synchronizes and stimulates rapid fusion of accumulated docked vesicles in response to physiological Ca(2+) concentrations. PMID: 22705946
26. The calcium binding site to the C2A domain of SYT1 has been identified; this SYT1 domain activates exocytosis of secretory vesicles during neurotransmitter release. PMID: 22475172
