Overview of Calcium Storage and Release

Overview of Calcium Storage and Release

Calcium ions are important for cellular signaling. To maintain the $Ca^{2+}$ concentration in the cytoplasm, calcium ions are pumped from the cytosol to the extracellular space and into the endoplasmic reticulum and sometimes into the mitochondria. Cell signaling occurs when the cell is stimulated to release calcium from intracellular stores.
