      Rationale: Phospholamban (PLN) is an inhibitor of cardiac sarco(endo)plasmic reticulum Ca2+ ATPase. PLN knockout (PLN-KO) enhances sarcoplasmic reticulum Ca2+ load and Ca2+ leak. Conversely, PLN-KO accelerates Ca2+ ...
    • RyR2 serine-2030 PKA site governs Ca2+release termination and Ca2+alternans
