PLN Antibody

1. 2 lethal PLN mutations, R9C and R25C, which lead to dilated cardiomyopathy, were studied by biomolecular NMR. R25C enhances phospholmaban dynamics and shifts the conformational equilibrium toward the R state. R9C drives the amphipathic cytoplasmic domain toward the membrane-associate state, enriching the T state. PMID: 29501609
