Pathogenesis Associated with a Restrictive Cardiomyopathy Mutant in Cardiac Troponin T is Due to Reduced Protein Stability and Greatly Increased Myofilament Ca(2+) Sensitivity

BACKGROUND: Dilated and hypertrophic cardiomyopathy mutations in troponin can blunt effects of protein kinase A (PKA) phosphorylation of cardiac troponin I (cTnI), decreasing myofilament Ca(2+)-sensitivity; however this effect has never been tested for restrictive cardiomyopathy (RCM) mutants. This...
