WebThe phospholamban (PLN) protein plays an important role in the calcium balance of the heart muscle cells. Heart disease is caused by a loss of cardiomyocytes (heart muscle cells), usually because of a heart attack or weakening of the cardiac muscle cells.

WebAs knowledge of the precise mechanisms governing cardiac hypertrophy and heart failure development increases, the availability of new therapeutic alternatives also grows. ... Ferrandi M, Barassi P, Tadini-Buoninsegni F, et al. Istaroxime stimulates SERCA2a and accelerates calcium cycling in heart failure by relieving phospholamban inhibition. WebIn cardiac muscle phosphoproteins as phospholamban and troponin I are thought to be of importance for regulation of contractility. The in vitro phosphorylation of phospholamban, a protein intrinsic to membranes of sarcoplasmic reticulum, increases the uptake of calcium ions by the sarcoplasmic reticulum (Tada et al. 1975). great meadows nj police department
