Phospholamban cardiomyopathy
WebJan 1, 2001 · Phospholamban was originally implicated in the regulation of calcium transport across the cardiac sarcoplasmic reticulum by the correlation of cAMP-induced stimulation of calcium transport by the Ca 2+ -ATPase, with the predominant phosphorylation of PLB by the cAMP-dependent protein kinase ( 110 125 213 215 ). WebNov 9, 2024 · Phospholamban (PLN) cardiomyopathy is a specific subtype of hereditary cardiomyopathy caused by PLN p. (Arg14del), a pathogenic variant in the gene encoding PLN, which is a protein with a central role in calcium homeostasis in cardiac tissue. This protein ensures proper contraction and relaxation of the human heart.
