Cardiac myosin binding protein-C phosphorylation accelerates β-cardiac myosin detachment rate in mouse myocardium

American Journal of Physiology-Heart and Circulatory Physiology, 2021
Length perturbation analysis was used to demonstrate that β-cardiac myosin characteristic rates of detachment and recruitment in the intact myofilament lattice are accelerated by Pi, phosphorylation of cMyBP-C, and the absence of cMyBP-C. The results suggest that cMyBP-C normally slows myosin detachment, including Pi-dependent detachment, and that ...

Myosin from cardiac muscle

Biochimica et Biophysica Acta, 1951
Abstract Myosin from cardiac muscle was prepared which seems to be free from contamination by F-actin. The electrophoretic mobility and sedimentation constant are the same as for crystallized myosin from skeletal muscle, but the sedimentation constant has another concentration dependence.

Biochemical characteristics of human cardiac myosin

Journal of Molecular and Cellular Cardiology, 1977
Abstract Myosin was purified from the left ventricles of eight patients. Samples of the ventricle were obtained immediately after the death of three patients whereas the rest were obtained from 2 1 2 to 20 h after the death. Human cardiac myosin, like the cardiac myosin from other mammalian species has only two light chains. The corresponding

β-Adrenergic regulation of cardiac myosin

Canadian Journal of Physiology and Pharmacology, 1987
Calcium-independent regulation of the contractile proteins of cardiac muscle has been studied using hyperpermeable cells from rat ventricles and sections of quickly frozen rat hearts. These preparations have been used to study maximum calcium-activated force, myosin ATPase activity, and the maximum velocity of unloaded shortening.

Cardiac Myosin Light Chains

Laboratory Medicine, 1992
The detection of circulating levels of cardiac myosin light chains (MLCs) recently has been proposed as a new biochemical marker of myocardial damage. In patients with unstable angina and acute myocardial infarction, measurement of MLCs seems to provide diagnostic information that differs from that obtained by determination of traditional cardiac ...
