Sarcolipin is a Conformation-Dependent Regulator of the Sarcoplasmic Reticulum Calcium Pump SERCA
Muscle relaxation is enabled by the sarco-endoplasmic reticulum Ca2+-ATPase (SERCA), which removes calcium from the cytosol and returns it to the lumen of the sarcoplasmic reticulum. During transport, SERCA adopts a variety of conformational states which differ in their structure and affinity for substrates. The transi...
