Phospholamban cardiomyopathie
WebFeb 28, 2003 · Phospholamban (PLN), an abundant, 52–amino acid transmembrane SR phosphoprotein ( 4 ), regulates the Ca 2+ ATPase SERCA2a. SERCA2a activity is decreased in human heart failure ( 5, 6 ), but whether this is a primary or secondary process that reflects changes in SERCA2a, PLN, and/or other molecules is unknown.
