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

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
