Spring 2020
Calcium homeostasis is essential and central to a variety of cellular processes from cell life and death pathways to metabolism to muscle contraction. One component that is essential to intracellular calcium regulation is known as the sarco(endo)plasmic reticulum Ca-ATPase, or SERCA. SERCA...

In human cells, oscillations in calcium concentration serve as a mechanism for controlling a variety of physiological processes including muscle contraction and relaxation. The sarcoplasmic reticulum (SR) is a calcium storage organelle in muscle cells that contains a calcium pump (SERCA) required...

When calcium enters the cytosol of a muscle cell from the SR, it initiates muscle contraction, while its removal by the sarco(endo)plasmic reticulum calcium ATPase (SERCA) induces muscle relaxation. SERCA's activity is regulated by Phospholamban (PLN), which can reversibly inhibit its apparent...

Oscillating cytosolic calcium concentrations dictate the contraction-relaxation cycles of muscle cells. Calcium release from the sarcoplasmic reticulum (SR) to the cytosol stimulates muscle contraction, while active transport of calcium back into the SR triggers muscle relaxation. Calcium...
