Introduction: The molecular basis of exocytosis of secretory insulin-containing granules (SGs) during biphasic glucose-stimulated insulin secretion (GSIS) of pancreatic β-cells remains unclear. Syntaxins (Syns) Syn-1A and Syn-4 are t-SNARE proteins situated on the plasma membrane that have been well studied to mediate insulin exocytosis. However, Syn-3, peculiarly more abundant in insulin SGs, has unclear function in GSIS.Methods/Designs: Confocal m...
