Myocardial infarction and regulatory myosin light chain.

Abstract

Myosin from cardiac muscle consists of two heavy chains and two pairs of light chain. Regulatory myosin light chain (RMLC) is phosphorylated by a Ca2+ and calmodulin dependent myosin light chain kinase. The impact of experimental myocardial infarction on cardiac RMLC was studied. The left anterior descending coronary artery of rabbits was ligated. Three, 7… (More)
