Hypertrophic cardiomyopathy (HCM) is primarily caused by mutations in β-cardiac myosin and myosin-binding protein-C (MyBP-C). Changes in the contractile parameters of myosin measured so far do not ...
(September 29, 2005, La Jolla, CA) Scientists from the Burnham Institute for Medical Research and the University of Vermont have captured the first 3-dimensional (3D) atomic-resolution images of the ...
Cell generated force plays essential roles in a wide range of biological processes, such as cell motility, cytokinesis, and tissue morphogenesis. In a study published in Nature Communications, a ...
Sarcomeres are small repeating subunits of myofibrils, the long cylinders that bundle together to make the muscle fibres. Inside the sarcomeres, filaments of the proteins myosin and actin interact to ...

How your muscles work and why they tire
From the first nerve signal to the final movement, your muscles rely on a complex chain of events involving nerves, proteins, and energy. Actin and myosin filaments slide past each other to create ...
"This process appears to be regulated by myosin-binding protein-C (cMyBP-C), which is a heart muscle protein," study author Kerry McDonald said. "Our study investigated its role in cardiac muscle ...
The novel cardiac myosin inhibitor aficamten improved peak oxygen uptake in symptomatic obstructive hypertrophic cardiomyopathy (HCM), the pivotal SEQUOIA-HCM trial showed. At 24 weeks, the mean ...
Cells use the polymerization of actin alone to create some types of movement, but many other forms of movement require interplay between actin and an enzyme called ...
