(1991) stated that phospholamban is a major substrate for the cAMP-dependent protein kinase in cardiac muscle. Phospholamban is an inhibitor of cardiac muscle sarcoplasmic reticulum Ca (2+)-ATPase (SERCA2a; see 108740) in the unphosphorylated state, but inhibition is relieved upon phosphorylation of the protein.
