WebAbstract Aims: To investigate whether phospholamban gene (PLN) mutations underlie patients diagnosed with either arrhythmogenic right ventricular cardiomyopathy (ARVC) or idiopathic dilated cardiomyopathy (DCM). 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 … See more Phospholamban, also known as PLN or PLB, is a micropeptide protein that in humans is encoded by the PLN gene.
