Zinc has been considered as a vital constituent of proteins, including enzymes. Mobile reactive zinc (Zn2+) is the key form of zinc involved in signal transductions, which are mainly driven by its binding to proteins or the release of zinc from proteins, possibly via a redox switch. There has been growing evidence of zinc’s critical role in cell signaling, due to its flexible coordination geometry and rapid shifts in protein conformation to perform biological reactions. The importance and... -

The secretion of insulin from pancreatic Ղ-cells is triggered by the influx of Ca2＋ through voltage-dependent Ca2＋ channels. The resulting elevation of intracellular calcium ([Ca2＋]i) triggers additional Ca2＋ release from internal stores. Less well understood are the mechanisms involved in Ca2＋ mobilization from internal stores after activation of Ca2＋ influx. The mobilization process is known as calcium-induced calcium release (CICR). In this study, our goal was to investigate the... -
