"This protein is found as a pentamer and is a major substrate for the cAMP-dependent protein kinase (PKA) in cardiac muscle. In the unphosphorylated state, phospholamban is an inhibitor of cardiac muscle sarcoplasmic reticulum Ca -ATPase (SERCA2) which transports calcium from cytosol into the sarcoplasmic reticulum. When phosphorylated (by PKA) - disinhibition of Ca -ATPase of SR leads to faster Ca uptake into the sarcoplasmic reticulum, thereby contributing to … " - Phospholamban cardiomyopathy
