WebThe Ca 2+ -triggered exocytotic process is regulated by synaptotagmin (Syt), a vesicular Ca 2+ -binding C2 domain protein. Synaptotagmin 1 (Syt1), the most studied major isoform among 16 Syt isoforms, mediates Ca 2+ -triggered synaptic vesicle exocytosis by interacting with the target membranes and SNARE/complexin complex. WebJan 14, 2004 · The nature of the exocytotic fusion pore remains obscure despite investigation into the regulatory mechanisms for exocytosis (Sulzer and Pothos, 2000). The main difficulty has been an inability to directly monitor release from single fusion pores.

Because the reduction of evoked release in csp mutants is counteracted by increased Ca(2+) levels, we suggest that CSP primarily increases the Ca(2+) sensitivity of the exocytotic machinery.
WebDec 12, 2011 · During granule exocytosis and insulin secretion, the elevation of local Zn 2+ concentration ( [Zn 2+ ]) is expected to be highest immediately adjacent to the plasma membrane where ZIMIR is localized. Thus, the fluorescence readout of ZIMIR should be highly sensitive to β cells’ secretory activity. Fig. 1. Design of ZIMIR. http://ccdb.ucsd.edu/browse/cellcomponent/Vesicle
