Calcium is involved in many physiological processes such as programmed cell death, fertilization, gene transcription, secretion (including neurotransmitter secretion) etc. For example, the SERCA pump is mainly found in skeletal muscle cells and cardiac cells. It is involved in the relaxation of skeletal muscle cells. Those cells contain a special endoplasmic reticulum called the sarcoplasmic reticulum which is the place of calcium storage. After contraction, calcium ions are transported from the cytoplasm into the sarcoplasmic reticulum through the SERCA pump. This causes the relaxation of the muscle cells because the cytosolic concentration of calcium decreases. The SERCA pump works together with the PMCA pump to export calcium ions from the cytosol and to set the resting level of the cytosolic calcium concentration.
