abstract：:Zinc (Zn2+) is the most abundant trace element in cells and is essential for a vast number of catalytic, structural, and regulatory processes. Mounting evidence indicates that like calcium (Ca2+), intracellular Zn2+ pools are redistributed for specific cellular functions. This occurs through the regulation of 24 Zn2+ ...
