Abstract

The endoplasmic reticulum (ER) and its specialized subcompartments such as the sarcoplasmic reticulum, is the main dynamic Ca2+ storage compartment of the cell. Key cellular functions are regulated, either directly or indirectly, by the free Ca2+ concentration in the ER. This article discusses the properties of Ca2+ storage in the ER and considers the functions that appear to be regulated by the Ca2+ stores within the ER, both in and around the ER and at a distance from it.

      The ER also stores calcium ions (Ca2+) and maintains intracellular Ca2+ homeostasis. Sarco/ER Ca2+-ATPase (SERCA) plays an essential role in this homeostasis by actively transporting Ca2+ from the cytosol to the SR/ER, and by generating an ∼10,000-fold Ca2+ concentration gradient across the membrane.3 Against this huge concentration gradient, SERCA pumps Ca2+ into the ER/SR lumen via large structural rearrangements driven by the hydrolysis of adenosine triphosphatase (ATP) as an external energy source.4,5
